The 4 Essential Realtor Lender Questions

Bankrate Realtor Survey: Verify these crucial terms before locking your mortgage rate.

0 of 4 Inquired

1 "What is your exact rate-lock period, fee, and float-down option?"

Lenders frequently offer 30-day locks for free, but if your closing drags to 45 days, extension fees can cost 0.25% to 0.50% of the loan amount ($1,050 to $2,100). Ask if a float-down option exists: if market rates drop before closing by 0.25%+, do they let you capture the lower rate without forfeiting your loan?

2 "What are your lender-controlled fees (Box A) vs pass-through third party costs?"

On the CFPB Loan Estimate, look strictly at Section A: Origination Charges (processing, underwriting, application). Section B & C (appraisal, title, escrow) are third-party services that cost roughly the same across lenders. An advertised rate that looks 0.125% lower may conceal $2,000 in higher Section A fees.

3 "What is your guaranteed closing timeline and appraisal turn-time?"

A lower rate quote is worthless if the lender fails to fund by your purchase contract deadline, causing you to lose earnest money or incur seller per diem penalties ($100-$250/day). Ask for their average contract-to-clear-to-close days in your local county.

4 "Will you match a competitor’s official Loan Estimate?"

Mortgage loan officers have discretionary pricing desk concessions. Presenting Lender B’s written Loan Estimate often motivates Lender A to match the rate or grant a $1,000-$2,500 lender credit to win your business without switching your loan file.

Why Rate Locking Creates the $3,343 Gap

Bankrate research reveals that mortgage shoppers who take the first offer without shopping 3+ lenders or timing their rate lock forfeit thousands in annual cash flow. Even a 0.50% to 0.75% difference on a median U.S. home purchase creates $250+ in extra payments every month.

Understanding APR vs Note Rate

The nominal note rate determines your monthly principal and interest payment, but the Annual Percentage Rate (APR) incorporates upfront discount points and lender origination fees over the life of the loan. Always audit both to spot hidden upfront costs.

When to Buy Discount Points

One mortgage point costs 1% of your loan amount ($4,000 on a $400k mortgage) and typically shaves 0.25% off your rate. If you plan to move or refinance within 3 to 5 years, paying points is often a net financial loss.
