I work with Fannie Mae asset managers in Sonoma, Napa and Lake counties. The answer depends a lot on the listing agent's individual asset manager but the first question is...Is this a lender required repair? Did the appraiser call the issue out on the appraisal and then the lender ask for the repair as a condition of funding the loan? If we are talking about dry rot and termite treatments they are pretty amiable to making those repairs to close the deal. If we are talking about replacing a roof or repairing a septic system then they may choose to look for a new offer where the buyer can purchase with cash and buy the property as is. As a rule when making offers on a bank owned property, if you can see the issue with your own two eyes when looking at the house and you make an offer on that house then you have made the offer with all the defects you are aware of when you made the offer. If things come up during inspections the seller (as with any home seller) can choose to accept, reject or counter your request for repairs. Good luck with your purchase.
