Investment Property Financing 101: What Lenders Actually Require

Financing a rental property is not the same transaction as buying the house you live in, and a lot of first-time investors get surprised by that partway through the process. The down payment is bigger, the rate is higher, and lenders want proof you can weather a few empty months before they will hand you the loan. Here is what actually goes into qualifying.

The Down Payment Is Bigger Than You Think

Primary residence loans can go as low as 3% to 5% down. Investment properties do not work that way.

For a single-unit rental on a conventional loan, plan on 15% down at minimum, and putting down 20% is worth it if you can, since it also lets you skip mortgage insurance. For a 2-4 unit investment property, the minimum typically jumps to 25% down.

There is no VA or USDA path here. Those programs are for owner-occupied homes, not rentals, so investment property financing runs through conventional, DSCR, or other non-QM options.

Your Rate Will Run Higher Than a Primary Residence

Expect an investment property rate to land roughly 0.5% to 1% higher than what you would get on a home you plan to live in. Lenders price it this way because a borrower is statistically more likely to stop paying on a rental than on their own home if money gets tight.

Your credit score moves this number a lot. Lenders generally want to see at least 640 to 700 to qualify at all, but the best pricing tends to show up closer to 740 and above.

Cash Reserves: The Requirement Primary Buyers Rarely Face

This is the piece that catches new investors off guard. Most primary residence loans require little to no reserves after closing. Investment properties are different.

Conventional lenders typically require 6 months of PITIA (principal, interest, taxes, insurance, and HOA dues, if applicable) sitting in reserve after your down payment and closing costs are covered. That money does not get spent, it just needs to exist in your accounts.

If you already own other financed rental properties, the requirement gets bigger. Fannie Mae guidelines generally add 2% of the unpaid balance on each additional financed property you own, on top of the 6-month baseline for the new purchase. Own three other rentals with a combined $900,000 in mortgage balances, and you could need an additional $18,000 in reserves just to close on property number four.

DSCR Loans: A Different Path That Skips Your Personal Income

If your personal income documentation is not the easiest fit for a conventional loan, or you are scaling a portfolio quickly, a DSCR loan (Debt Service Coverage Ratio) is worth understanding. Instead of qualifying based on your personal W-2s and tax returns, a DSCR loan qualifies the property based on whether its own rental income covers its own payment.

DSCR loans typically ask for a larger down payment, often in the 20% to 25% range, and they are not the cheapest financing option on the market. But for investors who are self-employed, own several properties already, or simply do not want their personal income scrutinized on every purchase, they solve a real problem.

Why This All Matters Before You Make an Offer

None of these numbers are flexible the way they can sometimes feel on a primary residence purchase. A lender is not going to waive your reserve requirement because you found a great deal. Knowing your real down payment, your real rate, and your real reserve number before you start touring properties keeps you from falling in love with a deal you cannot actually close.

Frequently Asked Questions

What credit score do I need to buy an investment property?

Most lenders want at least 640 to 700 to qualify, though scores of 740 and above typically get the best available rates on investment property loans.

How much higher is an investment property mortgage rate than a primary residence?

Plan on roughly 0.5 to 1 percentage point higher than a comparable primary residence rate, depending on your credit profile and down payment.

Do I need cash reserves to buy a rental property?

Yes. Conventional lenders typically require 6 months of PITIA in reserves after closing, and that requirement increases if you already own other financed investment properties.

What is a DSCR loan and do I need one?

A DSCR loan qualifies you based on the property's rental income rather than your personal income documentation. It is worth considering if you are self-employed, scaling a portfolio, or want to avoid extensive personal income paperwork, though it typically requires a larger down payment.
