Buying a house is a huge investment, you clearly have no clue how the process works; and you've done no research. Stuff like flood risk, is available free online; you can check it for yourself before even making an appointment to view. When viewing, you're expected to LOOK HARD at everything visible inside and out. Not the furniture and decor. look for old stains on ceilings, mould, leaky gutters, missing slates, wonky roof, cracks, rotten wood , ancient wiring switches and sockets, black soot marks above open fireplace. Does the place smell damp: or suspiciously of bleach and new paint? Don't comment or discuss; just look.
Drive round the area; look at the neighbourhood, noisy junctions, anything likely to be noisy or smelly (restaurant, pubs, school, factories, ). is there lots of litter, badly maintained buildings, burglar alarms, steel shutters on windows, empty shops and houses?
Or is it a Conservation Area? handy for transport and park? You can virtually walk round the area on google, do it BEFORE you make an appointment. Look up on rightmove, what prices localproperties have sold for and how often Do they sell frequently (why? ) or do people stay there for years?
Find out what surveyors DO (and don't do) . Many estate agents and solicitors websites will explain the process of buying, making offers etc.
Do you want a do-er upper? Do you have DIY skills or any clue what a new bathroom costs? Do you know what surveys, lawyers and legal fees cost? How much mortgage can you raise, how much can you afford to pay out of your regular income? ? Now re-think what your budget really is. Make a realistic wishlist ; number of bedrooms, garden? Ready to move in? Garage or parking? access to schools? Check out the local schools if you will have kids.
All that is your homework. For next time.
Meanwhile pull out of that purchase because you're so badly out of your depth that any sensible seller will probably refuse any further waste of their time. Write it off to experience and do better next time.
Bear mind that if you're hunting in that area, you may have to deal with that estate agent again. So be polite.
