DSCR loan vs conventional loan for an investment property

How do DSCR and conventional investment loans compare?

A conventional investment loan sold to Fannie Mae follows the Selling Guide and qualifies the borrower on personal income. A DSCR loan is business-purpose credit, written to the lender's own guidelines and qualified mainly on the property's rent against its full payment.

Exception: The DSCR column describes programs typical of what the financing professional shops. Terms vary by lender, property and borrower and are not guaranteed.

According to Selling Guide B2-2-03 and B3-3.8-01, Fannie Mae, and 12 CFR 1026.3(a), Consumer Financial Protection Bureau, as of October 2026.

Read the table as two different questions. Conventional asks whether you can afford the property. DSCR asks whether the property can afford itself, and for an investor whose tax return understates real cash flow, that second question can be the easier one to answer yes to.

For the regulation behind that difference, see why DSCR lenders don't ask for tax returns.

How many financed properties can I have with a conventional loan?

Fannie Mae limits second home and investment property loans underwritten through Desktop Underwriter to borrowers with up to 10 financed properties, under Selling Guide B2-2-03.

• Desktop Underwriter determines the number of financed properties for the loan casefile.
• B2-2-03 states that additional reserve requirements apply to second home and investment properties and points to Selling Guide B3-4.1-01.
• Selling Guide B3-4.1-01 sets those added reserves at 2% of the aggregate unpaid principal balance of the borrower's other financed properties for one to four financed properties, 4% for five to six, and 6% for seven to ten (DU only).
• The B2-2-03 topic is dated 11/05/2025.

Exception: This section covers Fannie Mae only. Freddie Mac and lenders that keep loans on their own books publish their own limits.

According to Selling Guide B2-2-03, Multiple Financed Properties for the Same Borrower (11/05/2025) and B3-4.1-01, Minimum Reserve Requirements (08/07/2024), Fannie Mae, as of October 2026.

Ten sounds like plenty until you're buying your seventh and the reserve requirement on your other loans jumps to 6% of their balances. That's usually when a portfolio approach earns a look: one blanket loan across several rentals, or a separate DSCR loan on each, written to the lender's own limits rather than DU's.

How much more does a conventional loan cost on a rental?

Fannie Mae's LLPA matrix, dated 09/30/2026, adds an investment property adjustment of 1.125% to 4.125% on purchase loans, depending on LTV. The adjustment is cumulative with the credit score and LTV grid.

Exception: The matrix sets what Fannie Mae charges on loans delivered to it, calculated on the acquisition date principal balance. How that cost reaches you, through rate or points, is up to the lender.

According to the Loan-Level Price Adjustment Matrix (09/30/2026), Fannie Mae, as of October 2026.

Run it on a $300,000 purchase loan at 80% LTV and the investment line alone is $10,125, before your credit score enters the math. That's why "conventional is always cheaper" deserves a rerun on your own numbers. The DSCR programs our financing professional shops also price mostly on LTV and credit score, so the honest comparison is two written quotes on the same property in the same week.

Does a conventional lender count my rental income?

Fannie Mae counts positive rental income as qualifying income only when the borrower has at least 12 months of property management experience. With less than 12 months, rental income can only offset the property's own PITIA.

• Selling Guide B3-3.8-01 names the borrower's most recent signed Form 1040, including Schedules 1 and E, as a source for documenting rental income.
• A signed lease showing at least 12 months of rental income can supplement the tax return when a property was owned for at least a year but Schedule E shows fewer than 365 fair rental days.
• B3-3.8-01 names Form 1007, the Single-Family Comparable Rent Schedule, for reporting monthly gross rent.
• The B3-3.8-01 topic is dated 09/02/2026.

Exception: Short-term rental income, departing-residence income and subject-property income each have their own Selling Guide topics with added rules.

According to Selling Guide B3-3.8-01, General Rental Income Information (09/02/2026), Fannie Mae, as of October 2026.

New investors get caught here more than anywhere. On your first rental, with no management history, the rent that ought to help you qualify only covers its own payment, and your salary carries everything else. Some DSCR programs accept first-time investors, often with tighter terms, so ask each lender how it treats a borrower with no rental history.

When does a DSCR loan make more sense than conventional?

A DSCR loan tends to fit when personal tax returns understate what you can carry, when you are near Fannie Mae's 10-property limit, or when you lack 12 months of property management experience.

• If your returns show heavy write-offs, then a loan qualified on rent avoids the personal income test that 12 CFR 1026.43 applies to consumer credit.
• If you already have close to 10 financed properties, then B2-2-03 is the conventional ceiling for DU files.
• If you have less than 12 months of property management experience, then Fannie Mae counts rental income only as an offset under B3-3.8-01.
• If your income documents are clean, your credit is strong and your LTV is low, then conventional pricing may still win, so compare written quotes.

Exception: This is a starting framework, not a recommendation for your situation. Loan fit depends on the property, the lender and your full financial picture.

According to 12 CFR 1026.43, Consumer Financial Protection Bureau, and Selling Guide B2-2-03 and B3-3.8-01, Fannie Mae, as of October 2026.

You may well end up holding both kinds of loan. The question is rarely which product is better in general. It's which one fits this property, at this point in your portfolio, and that changes as you add doors.
