“….I did the comps!”
As a seller’s agent in Rockledge and Viera, Florida I can assure you I know the comps. When working as a buyer's agent in Rockledge and Viera I do the comps (comparables) as well.
I can understand why your buyer would like that house. After all, it is move in ready.
And your buyer may still get that house when you re-do the comps!
A buyer's market does not mean buyers are so desperate to sell they will entertain any offer.
Not even short sale sellers are willing to accept any offer.
Even in baseball very little ever gets accomplished with low balls!
