Conventional loans are usually loans that are not insured or guaranteed by FHA, VA, or USDA. Many are underwritten to Fannie Mae or Freddie Mac rules, but the path can differ.
Decision Map
Where This Guide Fits
This is a general education piece. A real answer depends on the full file, property, timing, and current lender or investor guidelines.
Key Takeaways
- Fannie Mae and Freddie Mac both buy conventional mortgages, but their automated systems and guide rules are not identical.
- A file that is tight in one system may be worth testing in the other when lender access allows.
- Conventional still depends on loan limits, occupancy, LTV, property type, credit, income, assets, and investor overlays.
Plain-English Explanation
Fannie Mae's Desktop Underwriter and Freddie Mac's Loan Product Advisor are two different conventional underwriting paths. They often feel similar to borrowers, but they can evaluate risk, documentation, and eligibility differently. That is one reason a broker review can be useful: the question is not only 'conventional or not,' but which conventional path and lender menu actually fits the file.
Practical Details To Review
Why Fannie vs. Freddie can matter
Fannie Mae and Freddie Mac are both conventional agency paths, but their automated systems and guide details can treat some files differently.
- One path may be more favorable for a specific mix of income type, reserves, credit profile, property type, or loan-to-value.
- Some lenders have easier access to one agency path than another, which can change what is practical even when the loan is still conventional.
- Testing both paths can be useful when a file is close, layered, self-employed, investment-oriented, or property-sensitive.
Where conventional still needs a careful review
Conventional is broad, not automatic. It can be clean and competitive, but the details still decide whether it is the right lane.
- Loan limits, high-balance eligibility, occupancy, property type, condo status, and mortgage insurance can all change the structure.
- Seller credits and interested-party contributions have limits, and those limits can depend on occupancy and LTV.
- Conventional PMI should be compared against FHA MIP, VA funding fee treatment, USDA guarantee fees, and jumbo investor options when those paths are relevant.
Who It May Fit
- Primary residence, second home, and investment property borrowers.
- Borrowers comparing PMI, down payment, seller credits, and cash to close.
- Files where FHA or VA is possible but conventional may produce a cleaner long-term cost.
What Can Make It Harder
- Loan amounts above conforming or county high-balance limits.
- Condos, non-warrantable projects, investment properties, or layered risk.
- Self-employed income, recent credit events, large deposits, or limited reserves.
What David Would Compare
- Fannie Mae vs. Freddie Mac automated findings when the scenario is close.
- Mortgage insurance structures, seller-credit limits, reserves, and pricing adjustments.
- Whether conforming, high-balance, jumbo, FHA, or VA gives the cleaner path.
Common Mistakes
- Assuming conventional always means 20% down.
- Assuming PMI is always worse than FHA MIP.
- Ignoring occupancy and property-type pricing differences.
- Not testing both agency paths when the file is nuanced.
