Conventional Loans in Fullerton
Most conventional loans require a 620 minimum credit score. But in Fullerton's price range, you'll get meaningfully better rates at 740 or above.
Down payment starts at 3% for some conforming programs. Put down 20% and you skip private mortgage insurance entirely — that saves real money monthly.

Big retail banks advertise conventional loans, but they're showing you one set of rates. We shop across 200+ wholesale lenders to find better pricing.
Wholesale lenders rarely advertise to consumers. That's the advantage of working with a broker — access to pricing you won't find walking into a branch.
Conventional loans punish weak files harder than FHA does. Credit score, debt-to-income ratio, and reserves all hit your rate through pricing adjustments called LLPAs.
LLPAs — loan-level price adjustments — are Fannie Mae and Freddie Mac's way of charging more for riskier profiles. A 680 score with 10% down costs more than you'd expect.
FHA loans are easier to qualify for, but they carry mortgage insurance for the life of the loan in most cases. Conventional PMI drops off automatically at 80% LTV.
Jumbo loans kick in above the conforming limit. If your Fullerton purchase stays under that threshold, conventional conforming is almost always the smarter play on cost.
Fullerton has strong demand from Cal State Fullerton faculty, healthcare workers, and young professionals buying their first or second home.
Orange County's high cost basis means many Fullerton buyers are right at or near conforming loan limits. Knowing that threshold before you shop saves you from a jumbo surprise.
Lenders require a 620 minimum. Aim for 740+ to get the best rate pricing on your Fullerton purchase.
Yes — some programs allow 3% down. You'll pay PMI until you reach 20% equity, then it cancels.
PMI is private mortgage insurance. It drops off automatically once your loan balance hits 80% of the home's value.
For borrowers with strong credit and 10%+ down, conventional usually wins on total cost. FHA works better for lower credit scores.
