We have been in your position and even to this day, it is the house that got away. However, we are now in a house we love and we soon got over the last one. We eventually did become the people who bought a house and all the other viewings and an open day were cancelled as a result of our offer so we have been on both sides of this situation.
After we lost the first one, we ensured that we had registered with the local EAs so were on their list of people they called to view houses before they appeared on Rightmove. As it turned out, there was a lot of houses like this.
However, with our current house, it appeared on Rightmove just after midnight on a Friday night, I had drunkenly spotted it while randomly opening and closing apps on my phone but I knew there and then this was the house. I quickly sobered up, woke DH up to have a look and we drove to PIL's house by 8am on Saturday morning. The house was a 10mins walk from their house. EA told us that it wasn't ready and that there was an open day in a week's time.
PIL also thought it was the best we could get for our money so they cheekily went and knocked on their door. The owners weren't sure about what was going on but as it turned out, the EA had listed it by mistake and that it wasn’t meant to go live until Tuesday. PIL left our contact details with them to think about it and contact us while we were still in town if they wished.
2 hours later the house had disappeared off Rightmove. We received a phone call from the owner who had called the EA and described us, EA remembered us and told the owner that maybe they ought to give us a viewing as we were keen buyers. We had previously made an offer on another house with same EA but it had been rejected and still on the table when this house came up.
We viewed it Saturday afternoon, and within 30 seconds, I knew this was going to be my home. I was still stood in the hallway. We made an offer 10 mins later while stood in their dining room. It was rejected. The asking price was one of those ‘£225k - £250k. We already had a AIP in place, 1st time buyers whose rental was almost expiring. We made our official offer Monday morning. We wanted to pay just enough to tempt the vendor to cancel the rest of the other viewings and the figure we agreed on was between those two.
By the time our house appeared on Rightmove, it was already marked as sold. We are starting to look again now and I’m noticing that 50% of the houses we like the look of are coming up on Rightmove already sold so the EAs must have a list of buyers they can call once they have an instruction.
