After a long time looking, we have found a house to buy - it is the 'forever' family home and suitably pricey. We discovered that previous buyers pulled out because the house is built on a flood plane. There is, it seems, an underground waterway in the street. Flood risk is low, but a risk nevertheless, and is concerning me. Added to that, to secure it we had to offer asking price and more than we felt it was worth. A visit last week revealed many more maintenance issues than we had first thought, and that's also made me nervous as we are buying at the top of what we can afford. Can't figure out if my nerves are 'just natural' at this stage of the process or whether I should re-consider the whole thing given the sleepless nights its given me. I don't want to make a costly mistake. I've almost convinced myself I don't want to move at all. Anyone else experienced the jitters like this?
