Financing Investment Property: Conventional vs DSCR vs Portfolio Loans
Investment property financing is meaningfully different from primary residence financing in three ways: higher down payment requirements, higher interest rates, and additional documentation requirements. Understanding which loan type fits your situation — conventional, DSCR, or portfolio — determines both your entry cost and your ongoing cash flow.
Conventional Investment Property Loans: The Standard Path
Conventional investment property loans follow Fannie Mae and Freddie Mac guidelines. Key requirements and differences from primary residence:
| Factor | Primary Residence | Investment Property (Conventional) | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Minimum down payment | 3–5% (first-time buyer) | 15% (single-family); 25% (2–4 units) | |||||||
| Interest rate | Market rate | +0.5–0.75% above primary rate | |||||||
| Credit score minimum | 620 | 640–680 minimum (lender varies) | |||||||
| Debt-to-income limit | Up to 45–49% | Up to 45%; stricter in practice | |||||||
| Rental income credited | N/A | 75% of market rent credited to offset mortgage DTI | |||||||
| Reserves required | 2 months PITI (typical) | 6 months PITI for investment property; sometimes more | |||||||
| Maximum properties financed | N/A | Up to 10 financed conventional properties | |||||||
| The 75% rental income credit means if market rent is $1,800/month, lenders credit $1,350/month toward your DTI, reducing the effective mortgage payment impact on your qualification. | |||||||||
DSCR Loans: Qualify on the Property’s Income, Not Yours
DSCR (Debt Service Coverage Ratio) loans are the most significant financing innovation for real estate investors in the past decade. Instead of qualifying based on your personal income and DTI, the lender qualifies based on whether the property’s rental income covers the mortgage payment.
How DSCR Is Calculated
DSCR = Monthly Rental Income ÷ Monthly Mortgage Payment (PITIA). A DSCR of 1.0 means rent exactly covers the payment. A DSCR of 1.25 means rent is 25% more than the payment. Most DSCR lenders require 1.0–1.25 minimum DSCR. Some lenders offer "no ratio" DSCR at lower LTV for strong cash flow properties.
| DSCR Loan Feature | Typical Terms | ||||||||
|---|---|---|---|---|---|---|---|---|---|
| Minimum DSCR | 1.0–1.25 (lender-specific) | ||||||||
| Down payment | 20–25% typical | ||||||||
| Interest rate | Typically 0.5–1.0%+ above conventional (varies by lender and DSCR) | ||||||||
| Income documentation | None required (no personal tax returns, no pay stubs) | ||||||||
| Who qualifies | Self-employed investors, high-income investors with complex tax returns, investors who own multiple conventional mortgages already | ||||||||
| Maximum properties | No Fannie Mae 10-property limit; can build larger portfolios | ||||||||
| Short-term rental income | Some DSCR lenders accept Airbnb income with rental history | ||||||||
| DSCR loans are typically originated by non-bank portfolio lenders, not conventional lenders. They do not appear on the MLS or traditional rate comparison sites — you need a lender who specifically offers them. | |||||||||
Portfolio Loans: When You’ve Hit Conventional Limits
What Portfolio Loans Are
Portfolio loans are originated and held by the lender on their own balance sheet rather than sold to Fannie Mae or Freddie Mac. Because they are not sold to the agencies, they do not need to follow agency guidelines. This allows: more flexible underwriting, higher loan counts, different income verification, and financing for property types that conventional won’t touch (vacation rentals, mixed-use, distressed properties). Trade-off: higher rates (typically 1–2% above conventional) and shorter amortization terms (15–25 years in some cases).
Which Loan Type for Which Investor
| Investor Situation | Best Loan Type | Why |
|---|---|---|
| First investment property; W-2 income; good credit; under 10 properties | Conventional investment | Best rates; standard documentation; widely available |
| Self-employed; complex taxes; strong rental income | DSCR | No income documentation; qualifies on property cash flow |
| Over 10 financed properties (hit conventional limit) | DSCR or portfolio | No Fannie Mae property count limit for DSCR |
| House hacker: living in one unit of 2–4 unit property | FHA or conventional owner-occupant | 3.5–5% down; owner-occupant rates; dramatically better terms |
| Short-term rental (Airbnb) property | DSCR (STR-friendly lender) or portfolio | Some DSCR lenders accept STR income; conventional typically uses long-term rent |
| Distressed property or non-warrantable condo | Portfolio loan | Conventional won’t finance; portfolio lenders have more flexibility |
“The most common financing mistake I see first-time investors make is choosing their lender before they know their investment strategy. If you’re buying a single-family rental with W-2 income and good credit, a conventional investment loan is almost always the right answer. If you’re self-employed with write-offs that make your taxable income look low, a DSCR loan may let you qualify where conventional would deny you. Start with the investment strategy, then find the financing that fits it. Not the other way around.”

How much down payment do I need for an investment property?
Conventional investment property: 15% minimum for single-family; 25% minimum for 2–4 units. Exception: FHA or conventional owner-occupant financing for 2–4 unit properties you will live in: 3.5–5% down. DSCR loans: typically 20–25% down. Higher down payments produce better rates and cash flow.
What is a DSCR loan?
A Debt Service Coverage Ratio loan qualifies based on the property’s rental income rather than your personal income and DTI. DSCR = monthly rent ÷ monthly PITIA. Most lenders require 1.0–1.25 DSCR. No personal income documentation required. Useful for self-employed investors or those with complex tax returns.
What interest rate will I pay on an investment property loan?
Typically 0.5–0.75% above primary residence rates on conventional. DSCR loans: 0.5–1.0% above conventional (varies by lender and DSCR ratio). Portfolio loans: 1–2% above conventional. At 6.3% primary residence rate: expect 6.8–7.1% on conventional investment property.
How many investment properties can I finance?
Conventional (Fannie Mae): maximum 10 financed properties including your primary residence. DSCR loans: no agency limit; portfolio size depends on lender appetite and equity. Many serious investors use conventional for the first 3–4 properties, then switch to DSCR.
