Real estate investing means buying property to produce a return, and that return arrives four ways at once: rental cash flow, appreciation, tenant-funded loan paydown, and tax treatment. Most beginners start with a single rental house or a 2- to 4-unit building, where lenders in Align’s network generally look for 15% – 25% down and price the loan roughly 0.5% – 0.875% above an owner-occupied rate.

The numbers that decide whether a deal works are simple and few: net operating income, cap rate, cash flow, and cash-on-cash return. Learn more about real estate investing basics, including the four numbers every deal is judged on, how to find and vet a property, and how investment properties are financed and taxed.

Key takeaways:

• Four returns at once: Rent, appreciation, loan paydown, and tax treatment stack, which is why a property with modest cash flow can still beat its headline yield.
• The entry cost: Lenders in Align’s network generally want 15% – 25% down on a rental, and Fannie Mae requires six months of reserves, but a 2- to 4-unit building you live in can be financed with as little as 3.5% down through FHA.
• Judge with four numbers: Net operating income, cap rate, cash flow, and cash-on-cash return. If a deal only works on appreciation, it isn’t an investment yet.

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. Unlike a stock portfolio, it pays through four channels at once, and most beginners count only the first.

• Rental cash flow: What’s left after rent covers the mortgage, taxes, insurance, maintenance, and vacancy. The only one of the four you can spend. Most buy-and-hold investors target $150 – $400 per door.
• Appreciation: The property’s value rising over time. Because how real estate appreciation works is unpredictable year to year, treat it as a bonus, not the reason you buy.
• Loan paydown: Your tenant retires your mortgage balance for you, and the equity build accelerates every year you hold.
• Tax treatment: Rental income is taxed on net profit, not gross rent, and the building depreciates on an IRS schedule, ask a tax professional.

The engine underneath all four is borrowed money. You can control a $250,000 property with $62,500 of your own cash and keep the appreciation on the full value, which is what leverage in real estate buys, and why the benefits of investing in real estate compound faster than people expect. It cuts both ways, magnifying a bad purchase price as efficiently as a good one. This guide sits under our Real Estate Investing pillar.

How do you get started as a real estate investor?

Most first deals are a single rental or a 2- to 4-unit building, and you need the down payment plus closing costs plus reserves up front. Fannie Mae requires six months of reserves on investment property transactions, with an additional amount tied to the balances on any other properties you finance.

• Set the strategy first: Monthly income, long-term appreciation, and a tax-advantaged asset are three goals that buy three different properties. Start with investment strategies for beginners.
• Get the financing answer before you shop: Down payment minimums, reserve rules, and pricing adjustments decide which properties you can close on.
• Build a buy box: Price ceiling, markets, property type, minimum rent, acceptable condition. A written buy box lets you say no in ten seconds instead of ten days.
• Run the numbers the same way every time: One spreadsheet, one set of expense assumptions, every property. First-year mechanics are covered in how to become a real estate investor.
• Make offers on math, not feel: Your offer price is an output of the analysis.

The four numbers every deal is judged on

Four figures decide whether a rental works. We’ll run all four on a $250,000 Metro Detroit duplex renting for $1,150 per side.¹

What is net operating income (NOI)?

Net operating income is annual profit before financing, effective rent minus operating expenses, with the mortgage left out. Gross rent is $27,600; take out 6% for vacancy and you collect $25,944. Operating costs, taxes, insurance, repairs, a capital reserve, water and trash, run $10,400, leaving NOI of $15,544. Get net operating income wrong and everything downstream is wrong.

What is a cap rate?

A cap rate is NOI divided by purchase price. The return the property would produce if you paid cash. Our duplex returns $15,544 on $250,000, a 6.2% cap rate, mid-range against the 5% – 8% most Midwest buy-and-hold investors target. It grades the property, not your deal; a high number is compensation for risk, not a bargain. See how cap rates in real estate compare against local sales.

What is cash flow on a rental property?

Cash flow is NOI minus the mortgage payment. Finance the duplex with 25% down and principal and interest near $1,180 a month, and cash flow is $1,384 a year, $115 a month. That’s thin on a respectable cap rate: financing terms, not the building, turned 6.2% into $115. Hire a manager at 9% of rent and the deal goes negative. Budget management, vacancy, and reserves into your cash flow in real estate math before you offer.

What is cash-on-cash return?

Cash-on-cash return is annual pre-tax cash flow divided by the cash you invested, the number that grades your deal, not the property. Our buyer put in $62,500 down, $6,000 in closing costs, and $4,000 of make-ready, $72,500. Against $1,384, that’s a 1.9% cash-on-cash return, well under the 6% – 10% most investors want. A fine cap rate alone never closes a deal. Before offering, learn how to analyze a property’s rental potential.

How to find and vet a real estate deal

The profit in rental real estate is made at purchase, not at sale. You can’t manage your way out of overpaying. Sourcing and screening are your highest-leverage hours.

• Source wider than the MLS: Agent relationships, expired listings, estate sales, and tired-landlord referrals surface property before it is bid up.
• Screen the market first: A great building in a shrinking market is still a poor investment. Job growth, population change, and rent-to-price matter more than any negotiation; our investor market analysis hub covers the research toolkit.
• Underwrite before you tour: Run rent, taxes, insurance, vacancy, repairs, and reserves on paper and kill the deal there. Touring first is how people talk themselves into bad math.
• Do real due diligence: Verify rents against signed leases, pull two years of tax bills, confirm the non-homestead figure, and inspect fully. A disciplined real estate due diligence process turns an estimate into a decision.
• Negotiate on findings, not feelings: Inspection items, deferred maintenance, and below-market leases are all price. Bring documentation and be willing to walk.

Active vs. passive investing strategies

Every strategy below buys the same asset class; what changes is how much time, capital, and risk it consumes. Be honest about the time column.

Strategy	Time required	Capital required	Typical hold
Buy and hold	Low, ongoing	High	5+ years
House flip	High, concentrated	High	3 – 9 months
BRRRR / fixer-upper	High, then low	High, partly recycled	Indefinite
Wholesaling	High, constant	Low	Days to weeks
REIT shares	None	Price of a share	Liquid
Syndication	None after vetting	High, often accredited	3 – 7 years, illiquid
Crowdfunding	None after vetting	Low to moderate	Often illiquid

Two honest warnings belong here. Flipping is a construction business with a resale deadline, not a passive investment. Holding costs, permit delays, and one soft month for buyers can erase a projected profit, so read the real accounting on flipping houses: risks and rewards first. Wholesaling is regulated at the state level and can cross into unlicensed brokerage depending on how the contract is assigned.

On the passive side, REITs give you exposure without tenants or a mortgage, and they pass most of their taxable income through to shareholders, which is why investors buy them for yield. Syndications and crowdfunding sit in between: real ownership, real illiquidity, and a sponsor you didn’t hire. Our rental property management hub covers direct ownership.

How investment properties are financed and taxed

Investment property loans ask more of you than a loan on your own home, and guidelines vary more from lender to lender here than anywhere else. That’s the argument for shopping an investor file across a network: the spread between the best and worst quote on the same file is consistently wider than on a standard purchase. Our financing investments hub covers each option.

Three underwriting rules shape almost every conventional investor file. First, only 75% of documented market rent counts as qualifying income under Fannie Mae’s guidelines. The rest is treated as absorbed by vacancy and maintenance, so a property that cash-flows on paper can still stress your debt-to-income ratio. Second, investment property transactions require six months of reserves, plus an amount calculated against the balances on your other financed properties. Third, conventional financing tops out at 10 financed properties, where portfolio and DSCR lenders take over.

A debt-service coverage ratio (DSCR) loan qualifies the property instead of you: the lender sizes the loan against the rent the building produces and skips personal income documentation. Not every wholesale lender writes them, and terms differ sharply. If you’re refinancing to pull capital for the next purchase, Fannie Mae requires the first mortgage being paid off to be at least 12 months old and one borrower on title six months before disbursement. Track rates through Freddie Mac’s Primary Mortgage Market Survey.

Two tax provisions do most of the work. Real estate depreciation recovers the building’s cost over 27.5 years under IRS Publication 527; land is never depreciable, so the split between land and structure matters. Combined with deductible interest, taxes, insurance, and repairs, the tax benefits for real estate investors can turn a modest cash-flow number into a better after-tax result. And a 1031 like-kind exchange can defer the gain when you trade up instead of selling, if you identify replacement property within 45 days and close within 180 days or your return’s due date, whichever comes first. Talk with a tax professional before relying on either.

What Michigan investors should know

Michigan’s property tax system treats investors differently from owner-occupants, and misreading it is the most common budgeting error on a first rental.

• Non-homestead tax: A rental doesn’t qualify for Michigan’s principal residence exemption, so it’s billed at the non-homestead rate, which includes school operating millage the house next door is exempt from. Underwrite the non-homestead bill, not the seller’s.
• Uncapping at transfer: Michigan limits annual growth in taxable value for the current owner, but a transfer resets it. Ask the local assessor what the bill looks like after a sale.
• Cash-flow markets still exist here: Metro Detroit, Flint, Lansing, and parts of Grand Rapids still price where rent-to-value math can work, and you’re competing with fast buyers, so settle financing first.
• Landlord rules have teeth: Michigan caps residential security deposits, requires the deposit be held in a regulated account, and sets deadlines for the move-in inventory checklist and for returning the deposit. Confirm current limits and your city’s rental-registration ordinance before signing a lease.

FAQ: Real estate investing basics

Here are answers to common questions about real estate investing basics.

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

Plan on 15% – 25% down plus closing costs and six months of reserves, roughly $45,000 – $75,000 on a $250,000 rental. Two cheaper doors exist: buy a 2- to 4-unit, live in one side, and use FHA financing at 3.5% down, or start passively through a REIT for the price of a share. See how buying a home as an investment property works.

What is a good cap rate?

It depends on the market and the risk. Midwest rentals commonly trade at 5% – 8% cap rates, while lower-risk properties in high-demand metros trade at 4% or below. A higher cap rate is compensation for risk, not free money. Compare a property’s cap rate against nearby sales of similar buildings, never against a national average.

Can I use an FHA loan to buy a rental property?

Only if you live there. FHA requires owner occupancy, but it allows 2- to 4-unit buildings at 3.5% down, so you can occupy one unit and rent the rest, the most common low-cost entry into rental real estate. Lenders can also count a portion of the projected rent toward qualifying you, which is what makes the math work on a first purchase. FHA’s self-sufficiency test applies on 3- and 4-unit properties, so run that before you assume the payment.

Is real estate a better investment than stocks?

It depends on what you want from it. Real estate adds leverage, rental income, and tax treatment that index funds don’t have; stocks add liquidity, diversification, and zero maintenance calls. REITs sit between the two. This article is educational, not investment advice, talk to a licensed financial professional about your own situation.

The bottom line on real estate investing basics

Real estate investing pays four ways at once, rent, appreciation, loan paydown, and tax treatment, and four numbers decide whether a given deal earns them: net operating income, cap rate, cash flow, and cash-on-cash return. Expect 15% – 25% down on a rental, six months of reserves, and pricing that generally runs about 0.5% – 0.875% above an owner-occupied loan on the same file.
