Start with the same loan scenario
The lowest advertised rate is not automatically the least expensive mortgage. A Loan Estimate is a standardized document that helps you compare a lender’s proposed terms and estimated costs. Use it to compare actual offers rather than a headline on an advertisement.
Ask lenders to price the same purchase price, down payment, loan amount, loan type, and term. Compare estimates issued close together, because rates can change. Check whether the rate is locked and when that lock expires. A fixed-rate offer and an adjustable-rate offer have different risks; do not treat them as interchangeable.
Read the payment, not just the interest rate
On the first page, review the loan terms and projected payments. Check whether mortgage insurance is included and whether taxes and insurance are collected through an escrow account. An estimated payment may not include every housing expense.
Build your own monthly budget around the full cost of ownership: the mortgage, property taxes, insurance, any association dues, utilities, and maintenance. Ask what can change over time. Even with a fixed interest rate, taxes and insurance can change.
Separate lender charges from other costs
The second page breaks down closing costs. Look at origination charges, points, lender credits, and services you can or cannot shop for. Points may reduce the interest rate in exchange for an upfront payment; lender credits may reduce upfront costs in exchange for a higher rate.
Ask each lender to explain differences in third-party charges, prepaid costs, and escrow deposits. Some estimates differ because of assumptions, not because a lender is cheaper. Compare estimated cash to close as well as the payment, and ask whether a lower rate requires more money at closing.
Make the trade-off fit your plans
Review the comparison section on the third page, including APR and the five-year cost comparison. APR includes certain financing costs, but it is not the same thing as your interest rate or monthly payment. Consider these measures alongside the fees and loan features.
If you are considering points, ask for a written comparison with and without them. How long would it take for the monthly savings to recover the upfront cost? Your likely time in the home matters, and a future refinance is not guaranteed. Before closing, compare your Closing Disclosure with the Loan Estimate and ask about anything you do not understand.
