When mortgage payments start falling behind, a loan modification can look like a path back to stability. In general terms, that’s exactly what it is: a change to the loan terms designed to make the payment more manageable or resolve a default through a loss mitigation process.

This is where many applications start to unravel. A borrower may believe the package is “basically done,” while the servicer treats it as not ready for review at all.
