He wouldn't have a BPO on it unless he was trying for a short sale.
Bpo's are for loan samplings,pmi drops,pre-foreclosures,reo valuations, property checkups.
Unless he paid a bpo mill to have one performed on his property.
Was the bpo exterior or interior. If it was exterior the values are definetely off as interior condition wasn't noted.
If it really is that much and the friend is in bad health and has more equity than energy list it with a qualified broker.
Selling agents don't want a fsbo as they will do both sides of the deal for half the commission.
Your link had a bunch of junk about the property but I didn't see pics,or any usefull info. Having a pop-up is not a good idea either as it won't load on computers with pop-up blockers.
