Financing an investment property comes down to one question: how much cash you can put down, and whether you or the property carries the qualification. Conventional financing on a one-unit rental tops out at 85% loan-to-value, at least 15% down, and a 2- to 4-unit rental at 75%, meaning 25% down. Live in one unit for a year and an FHA loan on that same 2- to 4-unit building goes to 96.5% LTV, or 3.5% down.

Every other option is a variation on that tradeoff: pay more cash, occupy the property, or let the rent do the qualifying. Learn how investment down payments and reserves work, which loan types qualify you on the property instead of your tax returns, how to recycle equity you already own, and what changes on a Michigan rental.

Key takeaways:

• Down payment floor: Conventional financing caps a one-unit rental at 85% LTV (15% down) and a 2- to 4-unit rental at 75% LTV (25% down), while an owner-occupied duplex through FHA reaches 96.5% LTV, 3.5% down.
• Reserves are the hidden requirement: An investment purchase requires six months of payment reserves, plus 2% – 6% of the unpaid balance on every other financed property you own.
• Where the money is won: Only 75% of documented market rent counts as qualifying income, and investment pricing adjustments vary more between lenders than in any other loan category. Which is why Align Lending shops one investor file across 75+ wholesale lenders.

How much do you need down to finance an investment property?

Occupancy and unit count set the down payment before your credit or income enters the picture. Agency guidelines limit a non-owner-occupied one-unit rental to 85% LTV and a 2- to 4-unit rental to 75%, so the entry cost jumps from 15% to 25% the moment you add a door you don’t live in.

Financing route	Maximum LTV	Minimum down	Occupancy required?	Best for
Conventional, 1-unit rental	85%	15%	No	Standard buy-and-hold purchases
Conventional, 2 – 4 unit rental	75%	25%	No	Small multifamily investors
FHA, 1 – 4 unit	96.5%	3.5% (580+ score)	Yes	House hacking on limited cash
VA, 1 – 4 unit	100%	0%	Yes	Eligible veterans buying a duplex
Conventional cash-out refinance, 1-unit rental	75%	,	No	Pulling equity for the next purchase

Three requirements surprise investors more than the down payment does. Reserves: an investment purchase requires six months of the full payment, principal, interest, taxes, insurance, and dues, in verifiable assets after closing. Additional reserves: you also need 2% of the combined balance on your other financed properties with one to four of them, 4% with five or six, and 6% with seven to ten. The rent haircut: lenders count only 75% of documented market rent as qualifying income, because the other 25% is assumed to vanish into vacancy and upkeep.

Loan size is capped separately. The 2026 conforming limit is $832,750 on a one-unit property and $1,601,750 on a four-unit, see the county table in the FHFA conforming loan limit values. FHA runs its own schedule, with a 2026 one-unit floor of $541,287 and a ceiling of $1,249,125. Deciding between a straight rental and a property you’ll occupy first? Start with buying a home as an investment property, then investing in multi-family properties.

One caution on the owner-occupied route: FHA requires a borrower to move in within 60 days and intend to stay a year, and a three- or four-unit building must pass a self-sufficiency test. The payment can’t exceed the appraiser’s market rent for all units, less the greater of the appraiser’s vacancy estimate or 25%. Duplexes are exempt, which is why they’re the most common first buy.

What loan types can you use for an investment property?

Six categories cover almost every investor purchase, and they sort by one question: what gets underwritten, you or the building? Agency financing underwrites you; everything below it trades higher cost for a looser look at your returns. Our investing basics hub covers strategy; this is the paperwork.

• Conventional (agency) financing: The cheapest money available to an investor, priced off your credit, documented income, and the LTV limits above. Use it until a guideline stops you.
• DSCR loans: Non-agency loans that qualify the property rather than the borrower, measuring rent against the payment instead of your returns. Lenders in Align’s network generally want that ratio at 1.0 or better.
• Portfolio loans: Kept on the lender’s own books instead of sold, so the guidelines are the lender’s to write. See what a portfolio loan is and when it beats agency pricing.
• Non-QM and bank statement loans: Built for borrowers whose tax returns understate their cash flow. Non-QM loans for self-employed borrowers qualify on deposits or assets, not adjusted gross income.
• Bridge and hard money: Short-term and asset-based, priced for speed rather than holding. They fit a renovation or a deadline agency financing can’t meet, then get refinanced out, see how bridge loans are structured.
• Seller financing: The seller carries the note, which can solve a property no lender will touch. Terms, balloon date, and recording deserve an attorney, start with the pros and cons of seller financing.

Because Align is a broker, we can price a conventional file, a DSCR file, and a portfolio file from one conversation. A bank quotes the single product on its shelf, and on investment loans, the guideline spread between lenders is the widest anywhere.

How to finance an investment with equity you already own

Most second and third properties are bought with equity, not savings. Four routes reach it, differing in what they risk and how fast the money moves.

• HELOC on your primary residence: A revolving line you draw only when you find a deal, which makes it the most flexible down payment source. Rates are usually variable and your home secures the debt, see how a home equity line of credit works.
• Home equity loan: A fixed-rate lump sum, better suited to a known purchase price than an open-ended search. The pros and cons of home equity loans come down to certainty versus flexibility.
• Cash-out refinance: Replaces your mortgage with a larger one and hands you the difference. A guide to cash-out refinancing covers when resetting the first is worth it.
• Cash-out on a rental you own: Capped at 75% LTV on a one-unit and 70% on a 2- to 4-unit, with a borrower on title six months first. How to refinance an investment property walks through seasoning.

One exception matters if you buy with cash to win a bidding war. Agency guidelines allow delayed financing inside the six-month seasoning window when the purchase was an arm’s-length cash deal with no mortgage financing, documented on a settlement statement. The new loan is limited to your documented initial investment plus closing costs, prepaids, and points, capital back, not profit. Recycling those dollars is real estate leverage in practice.

How financing decides whether the deal actually works

Two properties with identical rent can produce very different returns based on nothing but the loan, which is why investors price financing before the offer. Run the qualifying math first.

Say you’re buying a $240,000 duplex in Waterford at 25% down: $60,000 down plus roughly $6,000 in closing costs. The units rent for $1,150 each, so gross rent is $2,300, but only 75% of it, $1,725, counts toward qualifying. If you owe $180,000 on your primary residence, you also need 2% of that balance, about $3,600, on top of six months of the duplex payment in reserves.¹ That reserve line sinks most first investor files, and it’s knowable before you write an offer.

Investment rates move with the broader market and carry pricing adjustments above owner-occupied levels, so track the weekly average in Freddie Mac’s Primary Mortgage Market Survey rather than any advertised number. Then translate the payment into a return: cash-on-cash return tells you whether your loan left a deal worth doing. For the rent assumptions behind it, use our investor market analysis hub.

How to keep financing deals as your portfolio grows

Agency financing has a hard ceiling: a borrower can carry at most ten financed one- to four-unit properties under automated underwriting, and the reserve requirement climbs from 2% to 6% of aggregate balances on the way there. Most investors hit the reserve wall first. Three moves get you past it.

Switch the qualification basis. DSCR and portfolio lenders don’t apply the agency property count, so the eleventh door is a product change, not a dead end. Consolidate. A portfolio lender can wrap several rentals into one note with one reserve calculation. Trade instead of selling, a 1031 exchange defers capital gains tax when you identify a replacement property within 45 days and close within 180, as covered in 1031 exchanges: rules and benefits.

Past a few doors, financing and operations become one conversation, because a lender underwrites your rent roll, vacancy history, and reserves together. Our rental property management hub covers operations; the full picture sits in the real estate investing pillar guide.

What Michigan investors should know

Michigan taxes a rental very differently from a home you live in, and the gap lands in your escrow line, often hundreds a month investors never budgeted.

• No principal residence exemption on a rental: Michigan’s principal residence exemption exempts an owner-occupied home from up to 18 mills of local school operating tax. A rental doesn’t qualify, so escrow must be built on the non-homestead rate.
• Taxes uncap the year after you buy: Michigan assesses property at 50% of true cash value and caps annual growth in taxable value for the current owner, but a transfer of ownership uncaps it. Underwrite the uncapped number, not the listing’s tax figure.
• Statewide limits, owner-occupied assistance: No Michigan county carries a high-cost limit, so all 83 counties sit at the 2026 baseline, $832,750 on a one-unit and $1,601,750 on a four-unit. State down payment assistance requires owner occupancy, which makes a duplex the on-ramp.

FAQ: Financing an investment property

Here are answers to common questions about financing an investment property.

Can I use an FHA or VA loan for an investment property?

Only if you live in it. Both programs require the borrower to occupy the property as a primary residence, and FHA asks you to move in within 60 days and stay a year. The property can hold up to four units, though, so you can buy a duplex or fourplex with 3.5% down on FHA or 0% down on VA, live in one unit, and rent the rest. Our guide to buying a multi-family home covers occupancy.

What is a DSCR loan?

A DSCR loan is an investment-property mortgage that qualifies on the property’s debt service coverage ratio, rental income measured against the loan payment, instead of your personal income and tax returns. Lenders in Align’s network typically want that ratio at 1.0 or higher and price DSCR above conventional. Start by evaluating a property’s cash flow potential, since that number is the whole application.

How much more do investment property loans cost than loans on a primary residence?

Meaningfully more, and the gap widens as your down payment shrinks. Investment properties carry loan-level pricing adjustments that scale with credit score and loan-to-value, so 15% down on a one-unit rental costs more per dollar borrowed than 25% down. Those adjustments differ by lender, which is why one borrower prices very differently across two wholesale lenders. See how the impact of interest rates on real estate investing reaches your return.

Can I use a HELOC on my home to buy a rental?

Yes, and many investors do. A line on your primary residence often prices below an investment-property loan and can fund a down payment or an all-cash offer you refinance later under the delayed financing exception. The tradeoff is real: your home secures the debt, and HELOC rates are usually variable, so an increase hits your household budget rather than the rental’s. Read using home equity wisely first.

The bottom line on financing investments

Investment financing is decided by occupancy and cash before anything else. Conventional financing caps a one-unit rental at 85% LTV, 15% down, and a 2- to 4-unit rental at 75%, or 25% down, while an owner-occupied duplex financed through FHA reaches 96.5% LTV at 3.5% down. Budget six months of reserves plus 2% – 6% of your other financed balances, expect only 75% of market rent to count as income, and remember the ten-property agency ceiling. When conventional stops fitting, DSCR and portfolio loans qualify the building instead of you.
