I'm Roger Peace, Director of Client Services at AVENTIS Homes, where I guide clients through FEMA-compliant luxury coastal construction in Pinellas County. While I'm not a mortgage loan officer, I work daily alongside lenders, investors, and buyers navigating Fannie/Freddie financing for coastal investment properties -- and I've seen these questions play out in real transactions. The biggest misconception I see is that investors assume Fannie/Freddie loans simply aren't available to them. They are -- up to 10 financed properties under Fannie Mae's guidelines -- but lenders often apply overlays that cap it at four, which creates confusion. That 25% down requirement is largely a lender overlay, not a hard GSE rule, though Fannie Mae's standard guidelines do require 15-25% depending on property type. On rental income: lenders typically use 75% of the subject property's market rent (per an appraiser's rent schedule) to offset the mortgage payment, not to qualify income. For existing rentals, expect Schedule E from your last two tax returns -- and be ready for depreciation add-backs to matter. The documentation that surprises investors most is the full lease agreement plus proof of receipt, like 12 months of bank statements showing deposits. The duplex-as-primary-residence strategy is genuinely underused. Move into one unit, put 5% down under owner-occupied terms, rent the other side -- that's a fundamentally different loan than an investment purchase. I've watched clients in our Tampa Bay market use this exact approach to enter coastal real estate far more affordably than they expected. -- Roger Peace, Director of Client Services, AVENTIS Homes | aventishomes.com
As a part owner of Best Credit Repair with 15 years of experience and FCRA certification, I specialize in preparing investors for the rigid credit and financial standards of GSE lending. My focus is on making complex credit requirements action-oriented so clients can qualify for the most competitive investment property terms. A major misconception is that 25% down is a hard requirement; it is actually a common lender overlay, as GSE guidelines often allow for 15% to 20% down on single-family investments. Investors are frequently surprised by "reserve requirements," which can demand six to twelve months of liquid payments for every financed property in their portfolio. Lenders apply a 75% factor to rental income; for example, a property renting for $2,000 provides $1,500 in qualifying income to offset the debt. Purchasing a duplex as a primary residence is a powerful "house hacking" tool because it allows for lower down payments and higher debt-to-income flexibility than a pure investment loan. Fannie Mae is generally preferred for "delayed financing" to recoup cash, while Freddie Mac offers specific advantages for investors with six or more financed properties. If your lender demands a 740 credit score when the GSE minimum is 620, you are facing a heavy overlay and should explore other institutions.

The most common misconception investors have is that Fannie Mae and Freddie Mac loans are only for primary residences. Both agencies allow 1-4 unit investment properties. The second misconception is that these loans are "easy." They require strong credit, documented income, and significant reserves. These are not no-doc investor loans — they are fully underwritten conventional mortgages. For a 1-unit investment property, Fannie and Freddie allow as little as 15% down. However, pricing adjustments are significant below 25%, which is why 20-25% is commonly quoted. For 2-4 unit investment properties, 25% down is typically an agency requirement, not just a lender overlay. If using rental income from the subject property, we use the appraiser's market rent (Form 1007) and apply a 25% vacancy factor. For example, $2,000 in market rent x 75% = $1,500 qualifying income. If the PITIA is $1,800, the property creates a $300 monthly shortfall for DTI purposes. For existing rentals, we use Schedule E from tax returns. If net income is $8,000 annually, that equals $667 per month in qualifying income. Depreciation can be added back since it's non-cash. The biggest surprise for investors is reserve requirements. It's common to need 6-12 months of PITIA for the subject property and sometimes additional reserves for other financed properties. Full tax returns are also required when rental income is involved. Buying a duplex as a primary residence versus an investment property is a major difference. If you occupy one unit for at least 12 months, you can qualify with as little as 5% down and better rates. As an investment, you're typically looking at 15-25% down and stricter guidelines. House hacking can significantly improve leverage. Common lender overlays include higher minimum credit scores, stricter DTI caps, higher down payments, or additional reserves. Reasonable overlays address risk layering. If a lender is restricting borrowers beyond agency guidelines without clear rationale, it's time to explore other options. Fannie and Freddie are very similar, but differences can arise in rental income calculations or property limits. A knowledgeable loan officer runs both automated underwriting systems to determine which agency provides the stronger approval.
