Buying a rental property is one of the better wealth-building moves a working professional can make. The mortgage rules are different from buying a home to live in, and the differences catch first-time investors off guard.
Here is the practical breakdown of what lenders want to see when you finance an investment property in 2026.
How much down payment you need
Investment property loans require a bigger down payment than primary residences. The standards in 2026:
- Conventional, single-family rental: 15-25% down. Most lenders price best at 25%.
- Conventional, 2-4 unit rental: 25% down is the standard, with some products available at 15% for strong borrowers.
- FHA on a 2-4 unit (you live in one unit): 3.5% down. This is the cheat code for first-time investors. You buy a duplex/triplex/fourplex, live in one unit, and rent the others. The mortgage qualifies as a primary residence.
- VA on a 2-4 unit (you live in one unit): 0% down for eligible Veterans.
The "house hack" option (buying a multi-unit and living in one) is dramatically cheaper than buying a pure investment property. If you're early in your investing journey, consider it seriously.
Credit and DTI for investment loans
Conventional investment loans want a 620 minimum credit score, but the best pricing starts at 720+. Your debt-to-income ratio (DTI) cap is usually 50% with strong compensating factors, often 45% in practice.
If you already own a primary residence and you're buying your first investment, the lender uses a piece of the projected rental income to help you qualify. Typically you can use 75% of the projected market rent (the appraiser estimates this) as offsetting income, since 25% is reserved for vacancy and maintenance.
Reserves: the silent qualifier
Lenders want to see 6 months of mortgage payments in liquid reserves after closing on an investment property. If you already own other rentals, the reserve requirement scales: typically 2 months of payments per additional financed property.
The reserves rule is what stops most people from buying their second and third rentals. Plan ahead. Park three to six months of mortgage payments per property in cash or near-cash so the math works when you find the right deal.
Interest rates on investment loans
Investment property loans typically price 0.50%-0.875% higher than primary residence rates. With the 30-year fixed averaging 6.30% for primary residences (Freddie Mac PMMS, April 30, 2026), investment loans are sitting in the 6.80%-7.20% range.
The pricing gap reflects higher default risk on rental properties. If a borrower hits financial trouble, they pay their primary mortgage first. Investment property mortgages get paid second, which makes them riskier for lenders.
DSCR loans: the alternative for serious investors
DSCR (Debt Service Coverage Ratio) loans are a non-QM product specifically for rental properties. The qualification is based on whether the property's rent covers the mortgage payment, not on your personal income.
- DSCR ratio: Most lenders want 1.0 to 1.25 (rent covers 100-125% of the mortgage payment plus taxes and insurance).
- No tax returns required. Useful if you're self-employed or have complicated income.
- Down payment: Typically 20-25%.
- Rates: Usually 0.75-1.50% above conventional investment rates.
- No limit on number of properties. Conventional financing caps you at 10 financed properties total. DSCR loans don't have that cap.
If you're scaling past 4 or 5 properties, DSCR loans become essential.
What's deductible: the tax angle
Investment property comes with real tax advantages. Mortgage interest, property taxes, insurance, maintenance, repairs, depreciation, property management fees, travel to and from the property, and a lot more are deductible against rental income. Depreciation alone is often the biggest tax shelter, letting you show a "loss" for tax purposes even when the property is cash-flow positive. Talk to a CPA who specializes in real estate to maximize this.
Common first-investor mistakes
- Buying based on Zillow's rent estimate. Get actual lease comps from the market and a real-estate-savvy agent.
- Underestimating maintenance and vacancy. Reserve 8-12% of gross rent for vacancy and 1-3% of property value annually for maintenance.
- Forgetting about insurance differences. Landlord insurance is more expensive than homeowner's insurance.
- Skipping the reserve check. The lender's reserve requirement is also your safety net. Don't deplete it to make the down payment.
