If they didn’t add square footage or an additional bathroom etc. and the work looks to be done in a “workman like manner” or some such phraseology, it shouldn’t make a difference to the appraisal. Well I haven’t came across this situation in the new lending era but it has been like that for at least ten years.
BTW I am a contractor besides a real estate agent. A good percentage of the time the local building dept. can’t find the permit record even if it is a few months old.Sometimes the building dept. doesn’t even follow up if the contractor blows off the final inspection on combination type remodel permits and other small work.
Yuo should get a copy of the appraisal and credit report if you want it.
