What is a conventional loan?

What Makes a Loan 'Conventional'?

The term "conventional" simply means the loan carries no government insurance or guaranty. This distinction matters because it determines who bears the risk of borrower default:

• FHA loans: The Federal Housing Administration insures the lender against loss — if you default, FHA pays the claim
• VA loans: The Department of Veterans Affairs guarantees a portion — if you default, the VA covers part of the lender's loss
• Conventional loans: The lender, investors who buy the loan, Fannie Mae or Freddie Mac, or a private mortgage insurer may share the risk of loss if the borrower defaults (private mortgage insurance protects the lender, not the borrower).

Because lenders carry the risk directly, they set higher qualification standards: better credit scores, lower debt-to-income ratios, and larger down payments. These requirements produce lower delinquency rates — but they also exclude the borrowers who need homeownership access most.

Conforming vs. Non-Conforming (Jumbo)

Within the conventional category, a critical distinction exists:

• Conforming loans meet Fannie Mae or Freddie Mac guidelines and can be purchased by these government-sponsored enterprises (GSEs) on the secondary market. This makes them cheaper for lenders to originate — and cheaper for borrowers. The conforming limit is $832,750 in most areas.
• Jumbo loans exceed the conforming limit and cannot be sold to Fannie/Freddie. Lenders keep these on their own books or sell to private investors, which means higher rates and stricter underwriting (typically 700+ credit score, 10-20% down, extensive reserves).

Most conventional loans are conforming. The conforming/GSE secondary market is what makes 30-year fixed-rate mortgages possible — few private investors would buy 30-year paper without the implicit government backing of Fannie and Freddie.

Why Do Conventional Borrowers Default Less Often?

Conventional underwriting screens borrowers before origination, and that screening is why conventional default rates run below FHA's — selection bias, not better luck:

• Higher credit score requirements screen out riskier borrowers before origination
• Larger down payments create equity buffers that prevent underwater situations
• Lower DTI requirements mean borrowers have more income headroom for payment shocks
• Borrowers who do encounter financial distress are more likely to have resources (savings, family support, refinancing options) to cure delinquencies before they become serious

The borrowers who can't meet conventional standards are pushed toward FHA loans. In August 2026, 13.64% of FHA loans in HUD's monthly report were at least one payment behind. The American Distress Index tracks the aggregate single-family mortgage delinquency rate in its Delinquency domain; the bank-booked single-family rate (1.86%) is the member it tracks and the FHA rate is supporting context. The two count differently (dollars at banks versus FHA loans in a survey), so their levels are not directly comparable. That bank-booked series is split by who holds the loan, not by loan type: a commercial bank's portfolio can include FHA-insured mortgages, and conventional loans held anywhere else sit outside it. It is a useful contrast to the FHA rate, but it is not a conventional-only measure and its level is not on its own evidence about conventional underwriting.

What Happens When Conventional Borrowers Default?

When conventional borrowers fall behind, they face the same foreclosure process as any borrower — governed by state law, not loan type. However, they have fewer government-specific safety nets:

• Government counseling: HUD-approved counseling is available to conventional borrowers too, and eligible Veterans and surviving spouses can receive VA counseling even on a non-VA-guaranteed loan. Conventional borrowers must work through servicer loss mitigation on their own or find a HUD-approved housing counselor.
• Servicer discretion: Regulation X requires servicers covered by its full evaluation rules to consider complete applications for help with mortgage payments that meet its timing and coverage requirements. Small servicers are exempt from those full procedures. Available modification programs depend on the loan's investor, and the regulation doesn't guarantee a particular modification.
• PMI cancellation at 80% on request, 78% automatically: This is an advantage — conventional borrowers who've built equity have lower monthly costs, making it easier to stay current.

The bank-booked single-family rate was 2.08% in the first quarter of 2007 and 11.48% in the first quarter of 2010. That rate counts FHA and VA loans on banks' books too, so it is not a conventional-only rate.
