How does credit score affect conventional rate?
Materially. Fannie/Freddie LLPA matrices price by credit-score bracket and LTV. Moving from 620 to 740 can drop the rate by half a point or more (or convert a point cost into a credit), and it cuts PMI substantially.
Plain-English explanation
LLPAs (Loan-Level Price Adjustments) are agency price adjustments that show up as points/credits on the rate sheet. The matrices have credit-score columns (620, 640, 660, 680, 700, 720, 740, 760, 780+) and LTV rows. The combined adjustment can swing a quote by 0.5-1.5%+ in rate equivalent. PMI factors also tier by credit and LTV. Run real quotes with current credit before shopping price points. Subject to current Fannie/Freddie LLPAs.
What can change the answer?
Recent late payments, thin credit history, disputed accounts, lender overlays, and AUS findings can change the answer.

Conventional guidelines are the rule. Your credit, income, DTI, PMI, LLPAs, and Florida payment math are what decide the actual answer.
