I'm going to view a house this weekend where it looks like a lot of work is needed, it's on a busy B road but set back slightly. I feel it is overpriced for where it is and for how much work needs doing but it is just a self build so nothing whatsoever to compare prices against.
How would you work out what to offer? It doesn't help as estate agents seem to be overvalued everything at the moment to get the business!
