Jumbo loan vs. Conventional (conforming) loan
The line between these two is the conforming loan limit. A loan at or below it can be sold to Fannie Mae or Freddie Mac (conforming/conventional); a loan above it is a jumbo, which lenders set their own rules for. Jumbo loans aren't worse — they just demand stronger credit, more reserves, and usually a bigger down payment because no GSE is backing them.
For self-employed borrowers, both use the standard income analysis, but jumbo underwriting scrutinizes that income — and your reserves — more closely.

Who should pick jumbo loan
Buyers in higher-priced markets whose loan amount exceeds the local conforming limit — strong credit and ample reserves make jumbo manageable.
Who should pick conventional (conforming) loan
Buyers whose loan fits under the conforming limit — lower down payment, lower credit bar, and the cheapest financing available.

FAQ
It's the maximum loan amount Fannie Mae and Freddie Mac will buy, set annually and higher in designated high-cost areas. Loans at or below it are conforming; above it, jumbo. Check your county's limit — see the loan-limits pages — since high-cost areas are well above the national baseline.
Generally yes. Jumbo underwriting examines self-employed income and reserves more closely than conforming loans. Strong credit, documented income (or non-QM jumbo options), and substantial reserves are the keys to approval.
