I'll try and make this as brief as possible.
DH and I put an offer in on a 3 bed 30s semi that needs 'some' modernising. we thought this would comprise of a new bathroom and kitchen and general decorating but survey has come back revealing it needs completely rewiring, a new boiler and guttering. Expected costs are at least £15k (with another £10k for kitchen and bathroom).
Initially we were tempted to withdraw from the purchase not only because of the cost but we've got a toddler and a baby on the way and I'm worried how we'll cope with the renovations but houses in our area just don't seem to be coming onto the market and I'm concerned if we let this one go, we could live to regret it.
Once it's been done up, it will be a superb house and has a stunning 120ft garden but the cost and amount of work needed doing is frankly a bit scary.
I should say that it is still affordable, even with the extra costs as we have a low mortgage and we have also had an offer on the house we currently live in.
