I just saw that there was an error on my mortgage. My name is misspelled with an O instead of an A in MANUALS. WIll this affect anything?

No, but yes. Obviously the lender needs to correct it. If it is still in the application stage, it is a pretty easy fix. If it already closed, you actually signed documents at closing stating you agreed to resign any documents if necessary. Just let the lender know... I lend in MN WI IA SD ND.
