Understanding lender overlays

The best time is after you have received a formal Loan Estimate from a lender but before you have locked your rate. This is when you have the most leverage. You can also try to negotiate after a rate lock if market rates have improved significantly, but lenders are not obligated to adjust a locked rate.

Underwriting is the lender’s detailed evaluation of your loan application. An underwriter will verify all the information you provided, assess your creditworthiness, confirm the property’s value via the appraisal, and ensure the loan meets all guidelines. They may issue conditional approvals, asking for additional documentation before making a final decision.

Lenders require an escrow account to protect their financial interest in your home. Since the property serves as collateral for the loan, the lender needs to ensure that the property taxes and insurance are paid. If taxes go unpaid, the local government could place a tax lien on the property, which could take priority over the lender’s mortgage. If insurance lapses, the property could be damaged or destroyed without coverage.

A fixed-rate mortgage is significantly easier to budget for in the long term. Because the payment is completely predictable, you can plan your finances for decades without worrying about fluctuations in your largest monthly expense.
