Real estate investing means buying property to earn income, appreciation, or both, and for most people it starts with one rental house, not a portfolio. Conventional financing on a single-unit investment property generally requires at least 15% down and a 620 credit score, and lenders in Align’s network usually want 20% – 25% down plus six months of payment reserves for the best pricing. If you’re willing to live in the building, the math changes completely: an owner-occupied 2- to 4-unit property can be financed with 3.5% down through FHA or as little as 5% down through conventional financing.

The appeal is that rental real estate pays you four ways at once, monthly cash flow, long-term appreciation, loan paydown, and tax deductions, but only when the numbers work before you buy, not after. Learn how real estate investing works, which strategies fit which budgets, how investment property loans get underwritten, and how to analyze a market and a property before you commit.

Key takeaways:

• Down payment reality: Most conventional loans on a 1-unit rental require at least 15% down and 2- to 4-unit rentals typically require 25%, but an owner-occupied duplex can be bought with 3.5% down through FHA.
• The two metrics that decide a deal: Cap rate (net operating income ÷ purchase price) grades the property, and cash-on-cash return (annual cash flow ÷ cash invested) grades your deal, most buy-and-hold investors underwrite to a 5% – 8% cap rate and budget 8% – 12% of rent for property management.
• Where to start: With less than $50,000 to invest, house hacking or a REIT usually beats a stand-alone rental, and financing is the first piece to solve, because investment property guidelines vary more from lender to lender than any other loan category.

What is real estate investing?

Real estate investing is buying, holding, or improving property to earn a financial return rather than to live in it, through rent collected, profit on resale, or appreciation over time. The asset can be a single rental house, a share of an apartment building, or shares of a publicly traded trust that owns thousands of properties.

Investors usually sort themselves into two camps. Active investors buy and control property directly: they choose the market, negotiate the purchase, arrange financing, and either manage the tenant relationship themselves or hire it out. Passive investors put money into a vehicle someone else operates, a real estate investment trust, a syndication, or a crowdfunding deal, and accept lower control in exchange for far less work.

Both routes tap the same underlying engine. Housing is a leveraged, income-producing hard asset: you can control a $250,000 property with $50,000 of your own money, collect rent against it every month, and keep the appreciation on the full $250,000. That leverage is the single biggest reason the benefits of investing in real estate compound faster than most people expect, and it’s also why a bad deal hurts more than a bad stock pick. If you’re weighing whether this is for you, start with the practical view of how to become a real estate investor and what the first 12 months actually require.

How do real estate investments make money?

Rental property produces four separate returns, and most beginners only count the first one. Understanding all four is what separates a property that looks like it barely breaks even from one that’s quietly building six figures of net worth.

• Cash flow: What’s left after rent pays the mortgage, taxes, insurance, maintenance, and vacancy. Positive cash flow is the return you can spend, and on a well-bought single-family rental it often runs $150 – $400 a month per door.
• Appreciation: The property’s value rising over time. Real estate appreciation is unpredictable year to year, which is why it should be treated as a bonus rather than the reason you buy.
• Loan paydown: Your tenant retires your mortgage balance for you. On a $165,000 loan, roughly $2,000 of principal disappears in year one and the number climbs every year after.
• Tax deductions: Mortgage interest, property taxes, insurance, repairs, and management fees are deductible against rental income, and the building itself is depreciated over 27.5 years under IRS Publication 527. The tax benefits of real estate investing often turn a modest cash-flow number into a much better after-tax result.

A worked example: a $220,000 rental in Metro Detroit

Say you buy a three-bedroom rental for $220,000 with 25% down. Your cash into the deal is $55,000 down, about $5,000 in closing costs, and $4,000 to make it rent-ready, $64,000 total. The house rents for $2,100 a month, or $25,200 a year. Budget 6% for vacancy ($1,512) and you’re collecting $23,688.

Operating costs run about $8,500 a year if you self-manage: $3,800 in property taxes, $1,500 in insurance, $1,900 in repairs, and $1,300 set aside for the next roof or furnace. That leaves net operating income of $15,188, a 6.9% cap rate. With principal and interest of $1,050 a month, annual cash flow is $2,588, a 4.0% cash-on-cash return, before the $2,000 of loan paydown and any appreciation.

Hire a property manager at 9% of collected rent and that $2,588 drops to roughly $456, or 0.7% cash-on-cash. That single line item is why experienced investors underwrite management costs into the offer price instead of discovering them later. Figures here are hypothetical and for educational purposes only; they aren’t a rate quote or an offer of credit, and your results will depend on your property, your file, and market conditions.

Real estate investing strategies, from beginner to advanced

There are five strategies that account for most residential real estate investing, and they differ mainly in how much capital, time, and risk tolerance each demands. Our investing basics hub covers each one in depth, along with the metrics used to compare them.

• Buy-and-hold: Purchase a property, rent it long-term, and let cash flow, paydown, and appreciation stack. It’s the lowest-drama strategy and the one most portfolios are built on. Start with real estate investment strategies for beginners if this is your first purchase.
• House hacking: Live in one unit of a 2- to 4-unit property and rent the others. Because you occupy the building, you qualify for owner-occupied financing. 3.5% down FHA or 5% down conventional. Instead of the 25% a pure rental would demand. It is by far the cheapest legal on-ramp into rental real estate.
• BRRRR: Buy, rehab, rent, refinance, repeat. You purchase undervalued property, force appreciation through renovation, then pull your capital back out with a cash-out refinance and do it again. It works best for investors comfortable with construction, the same skill set behind investing in fixer-uppers.
• Flipping: Buy, renovate, and resell within months. The upside is fast, but so is the downside: holding costs, permit delays, and a soft resale month can erase a projected profit. Read the honest accounting of flipping houses: risks and rewards before you budget a rehab.
• REITs and passive vehicles: Buy shares in a trust that owns income property. REITs must distribute at least 90% of taxable income to shareholders, which is why they’re used for yield. A guide to real estate investment trusts (REITs) explains how they’re taxed and where they fit alongside direct ownership.

Now that you know the strategies, here’s how to tell a good deal from a bad one.

The four numbers that decide whether a deal works

Every rental analysis reduces to four figures, and a deal that fails two of them should be repriced or passed on. Learn the formulas in prose once and you can underwrite a listing in about five minutes.

Metric	What it measures	How to calculate it	Common target
Net operating income (NOI)	The property’s annual profit before financing	Effective rent minus operating expenses (not the mortgage)	Positive after a full expense budget
Cap rate	Return if you paid cash, grades the property	NOI ÷ purchase price	5% – 8% in most Midwest markets
Cash-on-cash return	Return on the money you actually put in	Annual pre-tax cash flow ÷ total cash invested	6% – 10%
Rent-to-price ratio	Quick screen for whether rent can cover costs	Monthly rent ÷ purchase price	0.8% – 1% (the “1% rule”)

Net operating income is the foundation. Get it wrong and every downstream number is wrong. Cap rates let you compare two properties on equal footing regardless of how each is financed, while cash-on-cash return tells you what your specific down payment and loan terms produce. A useful sanity check: assume roughly 50% of gross rent will be consumed by operating expenses over the long run. Investors who skip that assumption are the ones surprised by year three.

Types of investment property and who each one suits

The property type you choose sets your ceiling on returns and your floor on effort. A single-family rental and a short-term vacation rental are completely different businesses that happen to share a mortgage product. Our investment property types hub breaks down every asset class, including the niche ones.

• Single-family rentals: The easiest to finance, easiest to sell, and easiest to manage, because you have one tenant and one roof. The tradeoff is total vacancy risk, when the tenant leaves, income goes to zero. See the full accounting on the pros and cons of investing in single-family rentals.
• Small multifamily (2 – 4 units): Still financed with residential mortgages, but income is spread across multiple tenants, so one vacancy doesn’t zero out the property. This is the sweet spot for most investors scaling past their first door, start with investing in multi-family properties.
• Short-term rentals: Nightly rates can produce two to three times the gross revenue of a long-term lease on the same house, offset by furnishing costs, higher turnover, platform fees, and local regulation risk. Investing in short-term rentals covers the underwriting differences.
• Commercial and mixed-use: Retail, office, and 5-plus-unit apartment buildings move into commercial underwriting, with different terms, shorter amortization, and depreciation over 39 years instead of 27.5. A primer on commercial real estate investing explains when the jump makes sense.

How to finance an investment property

Investment property loans cost more and ask more of you than a loan on the home you live in: expect a higher down payment, tighter credit standards, six months of reserves per property, and pricing adjustments that push the rate above owner-occupied levels. Because Align is a broker, we compare those adjustments across the whole network instead of accepting one bank’s answer, and investment guidelines vary more between lenders than in any other loan category. Our financing investments hub goes deeper on every option below.

Loan type	Typical down payment	Occupancy required?	Best for
Conventional, 1-unit rental	15% – 25%	No	Standard buy-and-hold purchases
Conventional, 2 – 4 unit rental	25%	No	Small multifamily investors
FHA, owner-occupied 1 – 4 unit	3.5% (580+ score)	Yes, 12 months	House hacking on a small budget
VA, owner-occupied 1 – 4 unit	0%	Yes	Eligible veterans buying a duplex
DSCR loan	20% – 25%	No	Self-employed or portfolio investors

Two underwriting details matter more than most investors realize. First, lenders typically count only 75% of documented market rent as qualifying income. The 25% haircut covers vacancy and upkeep, so a property that cash-flows on paper can still stress your debt-to-income ratio. Second, debt-service coverage ratio (DSCR) loans qualify the property instead of you: lenders in Align’s network generally want rent to cover 1.0 – 1.25 times the payment and skip personal income documentation entirely, which is how many investors keep buying after Fannie Mae’s 10-financed-property ceiling becomes a constraint.

Rates on investment property move with the broader market, so track the weekly average in Freddie Mac’s Primary Mortgage Market Survey rather than any single advertised number. For a full walkthrough of the options, including private money, partnerships, and portfolio lenders, see how to finance a real estate investment, and read buying a home as an investment property if you’re deciding between an owner-occupied and a straight rental purchase.

Financing is also how portfolios grow. A cash-out refinance on a 1-unit rental is generally capped at 75% loan-to-value, and the equity you pull becomes the next down payment. That recycling of capital is the whole point of real estate leverage. When you trade up rather than cash out, 1031 exchanges let you defer capital gains tax if you identify a replacement property within 45 days and close within 180.

How to manage a rental property, or hand it off

Property management is where paper returns meet reality, and it costs either 8% – 12% of collected rent or roughly 4 – 6 hours of your month per property. Neither answer is wrong; what’s wrong is failing to budget for one of them. Our rental property management hub covers the operational side end to end.

• Screening beats everything: A careful tenant screen. Income at roughly three times rent, verified employment, prior landlord references, and a credit and eviction check applied identically to every applicant. Prevents more losses than any other single practice. New landlords should start with becoming a landlord for the legal groundwork.
• Systems, not heroics: Online rent collection, a written maintenance request process, and a standing relationship with a plumber and an HVAC tech turn emergencies into tickets. How to manage a rental property walks through the whole operating routine.
• Scaling changes the job: Somewhere between the third and fifth door, self-management stops being a hobby. Tips for managing multiple rental properties covers the handoff to software or a manager.
• Short-term rentals carry regulatory risk: Cities can restrict or ban nightly rentals with little notice, and an ordinance change can wipe out a business plan overnight. Read navigating short-term rental regulations before you buy in an unfamiliar municipality.

How to analyze a market before you buy

The market decides the ceiling on your returns before you ever look at a specific house, and the three indicators that matter most are job growth, population change, and the ratio of median rent to median price. A property in a shrinking market can be a great deal on paper and a poor investment in practice. Our investor market analysis hub collects the full research toolkit.

• Start with the fundamentals: Employment, wages, and household formation drive rent. A structured real estate market analysis gets you from a vague sense of a city to a defensible rent projection.
• Score markets against each other: Rather than falling in love with one ZIP code, compare several using the same criteria, how to evaluate a real estate market for investment lays out the scorecard.
• Know where you are in the cycle: Expansion, peak, contraction, and recovery each reward different strategies. Real estate market cycles explains what to buy, and what to avoid, in each phase.
• Model the rate risk: Financing costs affect both your payment and your future buyer’s. The impact of interest rates on real estate investing shows how a shift in borrowing costs moves cap rates and values.

How to start investing in real estate: 5 steps

Most first purchases follow the same five steps, and the whole sequence usually takes 60 – 120 days from decision to keys.

1. Define the goal and the budget. Decide whether you want monthly income, long-term appreciation, or a tax shelter, then set a hard cash limit that leaves at least six months of reserves untouched. Tips for new real estate investors covers the common first-year mistakes.
2. Get the financing answer first. Down payment minimums, reserve rules, and rate adjustments determine which properties you can actually buy. Sorting this out before you shop keeps you from writing offers you can’t close.
3. Pick the market, then the property. Choose the metro and the neighborhood on data, then screen listings against your cap rate and cash-on-cash targets.
4. Underwrite and inspect ruthlessly. Verify rents with actual leases, pull two years of tax bills, and get a full inspection. A disciplined real estate due diligence process is what turns an estimate into a decision.
5. Close, stabilize, then repeat. Get the property leased and running smoothly for two or three months before you start hunting the next one.

What Michigan investors should know

Michigan’s property tax system treats investors very differently from owner-occupants, and it’s the single most common budgeting error on out-of-state and first-time rental purchases here.

• Taxes uncap when you buy: Michigan caps annual growth in a property’s taxable value for the current owner, but a transfer of ownership uncaps it to roughly 50% of market value the year after the sale. The seller’s tax bill is not the bill you’ll inherit, underwrite the uncapped number.
• No homestead exemption on rentals: The principal residence exemption exempts an owner-occupied home from up to 18 mills of local school operating tax. A rental doesn’t qualify, so budget the non-homestead rate. On a $220,000 house that gap can run well over $1,000 a year.
• Security deposits are regulated: Michigan law caps a residential security deposit at 1.5 months’ rent and requires you to return it or send an itemized list of damages within 30 days after the tenant moves out.
• Owner-occupancy unlocks state help: MSHDA down payment assistance is limited to owner-occupied primary residences, so it can’t fund a straight rental, but an owner-occupied duplex financed as a primary residence is a legitimate on-ramp for Michigan investors starting with limited cash.

When you eventually sell, Michigan transfer tax runs $8.60 per $1,000 of sale price. $7.50 state plus $1.10 county, and is customarily paid by the seller. Build it into your exit math, not your closing-day surprise.

FAQ: Real estate investing

Here are answers to common questions about real estate investing.

How much money do you need to start investing in real estate?

It depends on the route. A direct rental purchase typically takes 15% – 25% down plus closing costs and reserves, realistically $40,000 – $70,000 on a $220,000 property. House hacking with an FHA loan can cut that to under $15,000. And real estate crowdfunding platforms and REITs let you start with a few hundred dollars, with correspondingly less control.

What counts as good cash flow on a rental property?

Most buy-and-hold investors target $150 – $400 a month per unit after every expense, including vacancy and a capital reserve. The dollar figure matters less than the cash-on-cash return behind it. $200 a month on $30,000 invested is a far better deal than $300 a month on $90,000. Learn the full method for evaluating a property’s cash flow potential before you write an offer.

Can I use an FHA or VA loan to buy an investment property?

Not for a pure rental. Both programs require you to occupy the property as your primary residence, generally for at least 12 months. You can, however, buy a 2- to 4-unit building with FHA at 3.5% down or VA at 0% down, live in one unit, and rent the rest, then keep the loan in place when you move out later. Our guide to buying a multi-family home covers the occupancy rules in detail.

What is the biggest risk in real estate investing?

Overpaying. Leverage magnifies a bad purchase price the same way it magnifies a good one, and unlike stocks you can’t exit a rental in an afternoon. Vacancy, major repairs, and rising insurance costs are survivable if you bought right and kept reserves. Understanding real estate market risk helps you size those reserves realistically.

Do I have to pay tax on rental income every year?

Yes, rental income is taxable, but it’s taxed on net profit after deductible expenses, not gross rent. Depreciation is often the deduction that changes the answer, since it lets you write off the building’s value over 27.5 years without spending a dollar. See how real estate depreciation works, and talk with a CPA about your specific situation.

What is a good cap rate on a rental property?

Most buy-and-hold investors underwrite to a 5% – 8% cap rate, though the number only means something against comparable properties in the same market. Cap rate is net operating income divided by purchase price, so it grades the property independent of your financing. A high cap rate usually signals higher risk, not a bargain. See how cap rates in real estate are calculated.

How much down payment do you need for an investment property?

Most conventional loans require at least 15% down on a 1-unit rental and 25% on a 2- to 4-unit property, plus cash reserves of several months of payments per property. Rates price higher than owner-occupied loans, and guidelines vary more between lenders here than in any other category. Our guide to financing a real estate investment covers the options.

The bottom line on real estate investing

Real estate investing means buying property to earn cash flow, appreciation, loan paydown, and tax benefits at the same time. A conventional loan on a 1-unit rental generally starts at 15% down with a 620 credit score, 2- to 4-unit rentals typically require 25%, and an owner-occupied duplex can be bought with 3.5% down through FHA. Underwrite every deal to a 5% – 8% cap rate and a realistic expense budget, choose your market on job and population data, and decide upfront who manages the property. Do those three things and the fourth, financing, is the piece a broker can shop for you.
