What Counts as Competitive?

Competitive: 8.500% – 9.000%

Within normal market variation. Acceptable to close without pushback, though shopping a second lender is always worthwhile.

Slightly Above: 9.000% – 9.250%

Above the competitive band. Request a rate match from a competing lender and use it as leverage with your preferred lender.

Significantly Above: Over 9.250%

This rate is substantially higher than market. Get at least two additional quotes before proceeding — the difference over 30 years is significant.
