Thanks all.
Feeling really shit about it all again today.
I definitely think their new asking price is ridiculous. I looked on Zoopla and no similar or even bigger houses in the area has sold for close to what they’re asking- including one with a very lovely indoor pool.
Going to give the EA his statement but say I’m not prepared to do anymore and just draw a line under it. I looked at the listing last night and can see they also uploaded the video tour and drone footage he did- which includes his voice. They’ve just cut it off at the end where he gives his contact details 
A few of you asked what DH makes of all of this. He’s the same as me- loved the house but agog at how they’ve behaved and just wants to move on.
Funnily enough (and trying not to put too much detail on this) but he works in an area that’s very heavily linked to the economics of the property market and their third quarter reports for 2020 were issued yesterday and really don’t look good. Their internal economists are suggesting that there’s going to be a sharp shift and advised against investment in property.
So maybe all of this is a sign.
There is something weird going on. I'm not saying from your end. An EA who is part of a large national organization doesn't know what to do when his photos etc are used. They would have a legal team all over that. We are small and can get them taken down within 24 hours. I'm guessing that you were paying a buyers fee (we have never done this) and that is what the deposit is? People in England pull out all the time (I think it shouldn't be that easy) so not sure how the EA expects to get paid his fee. His contract, his fee, his problem - not yours.
So moving forward - some people are horrible and it sounds like you have dodged a bullet. Their house might be nice, but by the sounds of it the energy inside will be a bit warped. Your forever home will be there waiting for you. Avoid the National corporate EA's, and find the good local independents. If you dm me I can find you some in your area.
Predictions on house prices vary, and there are many economists who have called this wrong. In fact in our area, there was no need for the stamp duty holiday, as the market went mental as soon as lockdown was lifted. Things are normalizing now, but going into winter things tend to slow up anyway.
Anyone who advises against property needs their head read! If you were looking BTL this would be a different matter, I may tell you to hold off (dependant on where you live), but if you are looking for a home, carry on looking and forget what the "economists" say.
