I was told by a lender that FHA will not allow escrows for point of sale inspections which itemizes issues that need to be corrected prior to the closing or the buyer can be responsible if buyers sign escrow agreement.
Although it is rare for it to be allowable the statement is false. The FHA Appraisal is what they use to determine what items need repaired prior to closing. If there are items in the inspection that cannot be completed prior to closing due to seasonal limitations such as a roof replacement, exterior painting, and items similar in nature that cannot be performed in the winter then they will allow a repair escrow on the standard 203b program.
Unfortunately this is not the leniency you were probably seeking.
These guys have the 203k side down. I think that it depends on the market. Replacement value exceeds market value in many area's in the US. Even on new construction. So, the advice I would give is to make sure the cost of improvements make sense when added to the purchase price and compared to the market value.
Some minor repairs obviously do not add as much value as they used too. Replacing working items is a perfect example.
Heck some lenders allow you to use 203k to rip out everything but 1 wall of the foundation and totally re-built the home.
