We work with 200+ wholesale lenders, so we see the full range of conforming rates available to Costa Mesa buyers. Retail banks show you one rate. We show you the best of many.
Not every lender prices conforming loans the same way. Overlays — lender-specific rules stricter than Fannie or Freddie guidelines — can affect your rate and approval odds.
In Orange County, conforming loan limits matter. If your purchase price pushes above the county limit, you cross into jumbo territory — different guidelines, stricter reserves, higher rates.
We see buyers in Costa Mesa underestimate closing costs constantly. Budget 2–3% of the loan amount on top of your down payment. Skipping that math creates real problems at the closing table.
FHA loans accept lower credit scores but add mortgage insurance premiums for the life of the loan. Conforming loans drop PMI once you hit 20% equity — FHA usually doesn't.
Jumbo loans handle higher price points but require stronger financials. If your deal fits inside the conforming limit, staying conforming almost always means better terms.
Costa Mesa's home prices can push buyers close to the conforming limit fast. A few thousand dollars over the limit changes your entire loan program — and your rate.
Orange County's high cost of living means many buyers here are dual-income households. Combining income on a conforming loan works well when both borrowers have strong credit profiles.
Orange County qualifies for high-cost area limits set by the FHFA. Confirm the current limit with us before you shop — it affects your loan program entirely.
Yes. You can put down as little as 3–5%. PMI will apply until you reach 20% equity in the home.
All conforming loans are conventional, but not all conventional loans are conforming. Conforming means the loan meets Fannie Mae or Freddie Mac size and guideline limits.
Yes, but the condo project must be Fannie or Freddie approved. Non-warrantable condos don't qualify and need a different loan type.
Pricing improves significantly at 740 and above. Scores between 620–679 will see noticeably higher rates on conforming products.
