If your loan has not been approved, BofA must provide you with the denial letter that will show you the reasons for the denial. If these items can be addressed or revisited, you should do that in the interest of keeping the deal intact. Sometimes, mistakes are made or things overlooked, and a conversation with your loan officer may get to the bottom of it.
If the loan was denied due to the property/appraisal, you will need this information if you wish to continue with the seller.
As with all things in life, before correcting the problem, you must know what it is.
Let me know if I can help at any time --- either with additional perspective or with a new loan setup.
You know more than you think,
