Lenders differ in their mortgage modification requirements, but typically they require you to show that: You're at least one regular mortgage payment behind, or a missed payment is imminent. You've incurred significant financial hardship, for reasons including: Long-term illness or disability.
A recorded mortgage may be amended by an affidavit of amendment prepared by an attorney to correct clerical errors or omitted information. An amendment may not change any term, dollar amount, or interest rate in the mortgage, unless signed by the mortgagor and secured party.
Generally, once you've locked in a mortgage rate, the terms are fixed and usually cannot be renegotiated. However, some lenders offer a float down option, allowing you to negotiate mortgage rates if market conditions shift favorably during the rate lock-in period.
