I'm looking at buying a house in need of renovation. I think (though don't know) that it's structurally sound. However, I can't think that any improvements/mordernisation have taken place in the 60 odd years since it was built. It's also extremely grotty internally and has had some rodents in. So, if I work out the cost of bringing it up to a decent standard, and work out how much it would be worth in its renovated condition, how does that inform the maximum price I should pay for it? Is there a magic formula or percentage? It's to live in btw, but I don't want to take on this level of work for love alone! Any tips for negotiating with the EA also appreciated. I would really have thought it would have gone straight to auction the state it's in. Guess they're hoping to find some idiot who thinks a lick of paint will sort it out!
