Comparing Mortgage Offers: Look Beyond the Interest Rate
By Estates by Jay · Published
Two mortgage offers can be difficult to compare when the conversation starts and ends with the rate. For a Northern California home purchase, put the written Loan Estimates next to each other and check that they describe the same borrowing scenario. Then separate what you would pay upfront from what you would pay over time.
Start with a consistent scenario
The Consumer Financial Protection Bureau recommends comparing the loan amount, rate, payments, upfront costs and lender credits. It cautions that rates can change daily, so estimates issued on different days may reflect different market conditions.
Make a comparison sheet with one column per lender. At the top, record the estimate date, property, purchase price, down payment, loan amount, loan term and loan type. Ask each lender to explain any difference before treating the offers as comparable. Keep a revised estimate separate from the original so you know which version you are reviewing.
This approach works whether you are considering a home in Folsom, Petaluma or another Northern California community. Use the numbers for the actual property and your application rather than a general advertised rate. This guide does not quote current rates or predict what you will qualify for.
Compare upfront charges and credits together
CFPB directs buyers comparing lender costs to Section A for origination charges, Section B for services they cannot shop for, and Section J for lender credits. A lower estimate for property taxes or insurance does not establish that a lender’s offer is less expensive; lenders do not set those underlying costs.
The CFPB Loan Estimate explainer describes points as an upfront payment for a lower rate. Lender credits can offset closing costs, sometimes in exchange for a higher rate. Ask for an explanation of the tradeoff and, if useful, an alternative without points or credits.
Label each question with the section where it arose. For example: Why do these origination totals differ? What assumptions changed between these two versions? Which amounts are estimates from another provider? Request a written explanation you can keep beside the offer rather than trying to remember a phone conversation.
Check the payment and the cash needed
The CFPB explainer distinguishes principal and interest from the estimated total monthly payment, which can include mortgage insurance and escrow. It also directs buyers to identify taxes, insurance or assessments that are not escrowed and must be paid separately. A Loan Estimate does not necessarily mean the interest rate is locked.
On your sheet, give the monthly payment and estimated cash to close their own rows. Add a note for costs paid separately and ask the lender to confirm the rate-lock status and applicable terms. Keep funds needed for moving and your own post-purchase plans in a separate personal budget rather than assuming the loan form captures every expense.
Use the five-year comparison carefully
CFPB explains that subtracting the principal paid off from the total paid in the page-three In 5 years comparison gives the five-year interest-and-fee cost. For an adjustable-rate mortgage, that comparison assumes rates remain unchanged; actual costs can rise if rates increase.
Treat that figure as one comparison, not a forecast of how long you will own the home or keep the loan. Ask the lender to explain the implications of your likely timeline and any alternative loan structure. Do not build a purchase decision around an assumption that refinancing will be available later.
Finish with questions about service and timing
Before selecting an offer, make a short list of unresolved items and discuss them with the lender. Ask who will handle your application, how document requests will arrive and whether the proposed timing fits your purchase agreement. If you are considering changing lenders during a transaction, coordinate with your agent and the lenders before assuming the closing schedule will remain unchanged.
