Investment Property Financing: Conventional vs DSCR

When you're buying a rental property, the first question is usually "what kind of loan should I use?" For most investors, it comes down to two options: a conventional loan through Fannie Mae or Freddie Mac guidelines, or a DSCR loan. They both get you to the same place (owning a rental), but they work very differently. Here's how to decide.

Conventional Loans for Investment Properties

Conventional loans follow Fannie Mae and Freddie Mac guidelines. For investment properties, that means you'll typically need 15-25% down depending on the property type and number of units. You'll qualify based on your personal income, debt-to-income ratio, credit score, and reserves. The lender will want W-2s or tax returns, pay stubs, and bank statements, essentially the same documentation as a primary residence purchase.

The upside: conventional loans usually have the best interest rates for investment properties because the loan is backed by Fannie or Freddie. You can also count a portion of the expected rental income (usually 75%) to help offset the payment in your DTI calculation. If you have strong personal income and good credit, a conventional loan will almost always give you the lowest rate.

The downside: documentation requirements are heavy, and there are practical limits. Once you have 5-10 financed properties, qualifying gets progressively harder. Reserve requirements go up, and lenders start adding overlays. If you're a serious investor trying to scale, conventional financing starts to hit a ceiling.

DSCR Loans for Investment Properties

DSCR loans take a completely different approach. Instead of looking at your personal income, the lender only cares about whether the property's rental income covers the mortgage payment. That's the Debt Service Coverage Ratio: rent divided by payment. Most lenders want a 1.0 to 1.25 ratio, meaning the rent needs to cover 100-125% of the full payment including taxes, insurance, and HOA.

The upside: no tax returns, no W-2s, no pay stubs, no employment verification. This is huge for self-employed investors whose tax returns show less income due to write-offs, or for investors who already have a large portfolio and can't easily qualify through conventional channels. You can also close in the name of an LLC for liability protection, and there's no limit on the number of properties you can finance.

The downside: rates are higher than conventional, typically by 1-2% or more. Down payment requirements are usually 20-25%. And most DSCR loans come with prepayment penalties (usually 3-5 years), which means you'll want to plan ahead if you think you might sell or refinance soon.

Which One Should You Use?

For your first few investment properties, conventional financing is usually the better deal if you can qualify. The rates are lower, the terms are better, and the documentation, while annoying, is manageable. If you have a W-2 job with solid income and fewer than 5-6 financed properties, start here.

Switch to DSCR when conventional stops working for you. That tipping point is different for everyone, but common triggers include: you're self-employed and your tax returns understate your real income, you already have several financed properties and qualifying is getting difficult, you want to close in an LLC, or you just don't want to deal with the documentation requirements. Some investors use both: conventional for properties where they want the best rate, and DSCR for properties where they need the flexibility.

A Few Things to Watch

Regardless of which route you choose, make sure you understand the reserve requirements. Conventional lenders want to see 6 months of reserves for each financed property once you get above a certain count. DSCR lenders have their own reserve requirements too, usually 3-6 months.

Also pay attention to how the rental income is calculated. Conventional loans use 75% of the appraised market rent. DSCR lenders may use the actual lease, the appraiser's market rent estimate, or in some cases, documented short-term rental income from platforms like Airbnb. The method can make a big difference in whether the deal works.
