Financing an investment property follows the same basic mortgage process as buying a home you’ll live in — you apply, document your finances, and get underwritten. The differences show up in the details: larger down payments, closer scrutiny of your reserves, and rules around how much of your expected rental income actually counts toward qualifying. Understanding those differences before you start house hunting is what keeps your offer realistic and your closing on schedule.
What Counts as an Investment Property?
An investment property can be a single-family residence, a multi-unit property, or a condominium — most commonly used as a rental, though it can also serve as a second home for your family. The distinction that matters to underwriting isn’t the property type; it’s occupancy. If you won’t be living there, it’s evaluated as non-owner-occupied financing, which carries different terms than the mortgage on your primary residence.
Down Payment and LTV Requirements
Investment properties require more equity upfront than owner-occupied homes — this is the single biggest structural difference in the financing:
- Single-family investment property: typically 15% minimum down, though 20–25% is common depending on your credit profile and the lender
- 2–4 unit investment property: typically 25% minimum down
- No PMI safety net: unlike owner-occupied financing, private mortgage insurance generally isn’t available on investment properties, so the higher down payment isn’t optional — it’s the lender’s primary protection against risk
For a deeper look at how your down payment translates into loan-to-value ratio and what that means for your rate and terms, see our guide on loan-to-value ratio for investment properties.
Credit Score and DTI Requirements
Lenders generally expect a stronger credit and income profile for investment property financing than for a primary residence:
- Credit score: while some conventional guidelines technically allow scores in the 620s, most lenders want to see 680 or higher before extending competitive pricing on a rental property loan
- Debt-to-income ratio (DTI): generally capped around 43–45%, calculated the same way as any mortgage — total monthly debt obligations divided by gross monthly income
A stronger credit profile doesn’t just affect approval odds — it directly affects your rate, since investment property pricing already runs roughly 0.5–0.75 percentage points above owner-occupied rates industry-wide.
Cash Reserve Requirements
Reserves get more scrutiny on investment property financing than on a primary home purchase. Most lenders want to see six months of mortgage payments (principal, interest, taxes, and insurance) available in liquid or near-liquid assets after your down payment and closing costs are covered. If you already carry financing on other investment properties, expect reserve requirements to stack across your portfolio rather than reset with each new purchase.
Using Rental Income to Qualify
Expected rental income can help you qualify for an investment property loan, but lenders don’t count it dollar-for-dollar. Most guidelines only credit roughly 75% of projected rent toward your qualifying income, building in a cushion for vacancy and maintenance. A signed lease on the property, if one exists, strengthens your case further. This is a detail worth running by your loan officer early — it can materially change your qualifying numbers versus what you’d assume from gross rent alone.
Loan Program Options
Conventional financing is the most common route for 1–4 unit investment properties, offering predictable fixed-rate terms and no occupancy requirement.
FHA and VA “house hacking” is a lower-down-payment path many investors overlook: if you purchase a 2–4 unit property and occupy one unit yourself, you can use owner-occupied financing — FHA at as little as 3.5% down, or VA at 0% down for eligible borrowers — while renting out the remaining units. This is genuinely one of the more accessible ways into a first investment property, though it does require living in the property, typically for at least a year.
Jumbo financing applies once your loan amount exceeds conforming limits, which is common with higher-value investment properties or multi-unit purchases in competitive markets. See our Jumbo loan program for details.
Tapping existing equity is another path worth considering if you already own a home: a HELOC or cash-out refinance on your current property can fund the down payment on your next one, consolidating your financing into a structure that fits your broader portfolio strategy.
Note: some lenders in the market also offer DSCR loans, which qualify borrowers based on the property’s rental income rather than personal income or tax returns. This can be worth exploring for self-employed investors or those with complex income — ask your loan officer whether this fits your situation.
How Many Investment Properties Can You Finance?
Under standard conventional guidelines, investors are generally limited to 10 financed properties total, including your primary residence. Once you’re carrying more than four financed properties, expect stricter requirements across the board: higher down payments, tighter credit score minimums, and more extensive reserve documentation. This is worth planning for early if you’re building a multi-property portfolio rather than buying a single rental.
The Bottom Line
Investment property financing isn’t harder because lenders are being difficult — it’s structured around real risk differences between a home you live in and one you don’t. Knowing the actual down payment, reserve, and income requirements before you start shopping is what keeps your offer competitive and your closing timeline realistic.
Milend has been guiding investors through exactly this kind of financing since 1995. As a family-owned, Atlanta-based lender, we handle investment property financing from pre-qualification through the end of escrow — and if you already own a rental and it’s time to revisit your terms, our investment property refinance team can walk you through that too.
What I commonly get asked?
What is the minimum down payment for an investment property?
Conventional financing typically requires at least 15% down for a single-family investment property and 25% for a 2–4 unit property. Some lenders may require 20% or more depending on your credit profile, since PMI generally isn’t available on investment properties.
Can I use rental income to qualify for an investment property loan?
Yes, but most lenders only count roughly 75% of the projected rent toward your qualifying income, to account for vacancy and maintenance costs. A signed lease can strengthen your application further.
How much in cash reserves do I need for an investment property?
Most lenders require six months of mortgage payments (principal, interest, taxes, and insurance) in reserves after your down payment and closing costs, and that requirement can increase if you already hold financing on other investment properties.
Can I buy an investment property with less than 20% down?
Yes, in certain cases. Some conventional programs allow as little as 15% down for a single-unit property with strong credit. Additionally, purchasing a 2–4 unit property and occupying one unit yourself opens the door to FHA financing at 3.5% down or VA financing at 0% down for eligible borrowers.
How many investment properties can I finance at once?
Under standard conventional guidelines, investors can typically finance up to 10 properties total, including their primary residence. Requirements become stricter — higher down payments, higher credit score minimums, more reserves — once you exceed four financed properties.
Is the interest rate higher for an investment property loan?
Yes, typically. Investment property rates generally run about 0.5 to 0.75 percentage points higher than rates for the same borrower on a primary residence, reflecting the additional risk lenders take on with non-owner-occupied financing.
