Buy your first rental the way a bank already understands.
Fannie Mae and Freddie Mac financing qualifies you the traditional way — your income and your debt-to-income ratio — not your future rent roll. It's the standard on-ramp for a 1–4 unit purchase, and the right starting point before anything more advanced.
This is the conventional lane — not the rental-income lane.
Both paths can fund the same duplex. They ask a different question to get you there. Knowing which one you qualify for today is the first decision, not the last.
Qualify on your income
- UNDERWRITTEN ONYour personal income, credit, and existing debt (DTI)
- BEST FORFirst or second rental property, 1–4 units
- DOCSPay stubs, tax returns, W-2s or 1099s
- RATE PROFILETypically the lowest rate available on an investment purchase
Qualify on the property's rent
- UNDERWRITTEN ONThe property's rental income covering its own debt
- BEST FORInvestors scaling past what their personal income supports
- DOCSLease or market rent estimate — no personal income docs
- RATE PROFILESlightly higher rate for the income flexibility
What the bank asks you to put down.
Conventional down payments for investment property scale with unit count, not price. Here's the typical range before your loan officer runs your specific scenario.
Single-family rental. The lowest entry point for a first purchase.
A duplex. Rental income from the second unit can offset some qualifying, even here.
Triplex or fourplex. Same down payment tier as a duplex, more doors producing income.
Figures are typical ranges for conventional investment financing, not a quote. Exact down payment, rate, and reserve requirements depend on credit, occupancy history, and the specific property — confirm yours before you write an offer.
Income and DTI qualifying, plainly.
Four numbers decide most of this. Know them before you shop for a property, not after you're under contract.
| Measurement | What it means | Why it matters here |
|---|---|---|
| DTI Ratio | Your total monthly debts, including the new mortgage, divided by your gross monthly income. | Most conventional investment approvals sit at or under roughly 45%. |
| Qualifying Income | Documented W-2, 1099, or tax-return income — averaged over a recent period. | This is the number the loan is sized against, not the rent you expect to collect. |
| Reserves | Verified savings left over after closing, measured in months of mortgage payments. | Investment properties typically require more reserves than a primary home. |
| Credit Profile | Your score and history across existing accounts. | Sets both your approval odds and where your rate lands. |
Three measurements every first-time investor should know cold.
Not qualifying math — property math. These tell you whether a deal is actually good, independent of how it's financed.
ROI
What you actually earn on the money you put in — down payment, closing costs, and any repairs — over a year.
Cap Rate
A quick way to compare properties against each other, independent of how each one is financed.
Reserves
Your cushion in months. Lenders check it at closing; smart owners keep checking it after.
