I put in an offer for a property and heard nothing for several days. I kept on looking and found another possible house ( a fair bit more expensive though). At the same time I contacted the orginal agent to find out what was going on, and pursued the new property a bit more. By the time I eventually heard back from the agent and they said that they would accept my offer, I had given up. I am still not sure about the other house though. I don't know if IWBU to go back and make the offer again. I had no intention of not going through with the original offer but it was 10 days before they got back to me and as I said I started looking elsewhere.
