Hawk, that absolutely sucks! Like you didn't know.. I'm really sorry. Did you have any other viewers interested or put in offers even, that you could maybe go back to?
So we had a very promising second viewing. Said he really loved it, just needed to crunch some numbers, then nothing for a couple of days. Hoping he was just really "crunching", but no, he'd decided not to make an offer. Gutted. I really thought he would and he was chain free!
We have two houses we're interested in now, both completely different. One is a proper doer upper semi, but with an absolutely beautiful garden and the other is ready to move into, but with a small, quite over looked garden. The second would probably be harder to sell on in the future. Head's with the first one, heart's with the second. Not that it really matters, as we still haven't bloody sold! 
We were having a second viewing on house number two tomorrow and assumed we'd be in a position to put in an offer, but nope.
Had a chat with our EA and said we were concerned with the amount of viewings we've had with no (serious) offers. They just said there's nothing we can do and to keep going.
We have one viewer penciled in for this weekend and I'm very tempted to do it myself. They're not actually on the market yet, but apparently their flat should sell quickly....but then, don't they always say that? 🤔 Probably.
Can I ask how many of you who are on with an agent, decide to do viewings yourself?
