Valid real estate offers must be in writing, and signed
Nov 22, 2015 1:00 AM - Q. My wife and I made an offer on a short-sale home, which the sellers agreed to for $240,000. We gave our $2,500 earnest money with the offer. The bank countered for $15,000 more ($255,000). Our agent then wrote a letter to the seller's agent giving our counteroffer of an additional $5,000 ($245,000).
