I also worked on something nearly identical in US. It also failed with a bang. The site had a similar value proposition as the OP. $995 and off you go (we also tried other price points).

At the end of the day we just couldn't get enough customers. That is despite spending some serious bucks on advertising with Facebook and others.

I suspect you are right - home purchase/sale is too complicated for a regular consumer from a legal and practical standpoint and cost of failure is high. It's better to hand it off to a professional.
