First time buyer here, recently had an offer accepted on a 2 bed bungalow. The seller has accepted my offer (5k off asking price) but has made it clear from the start that there will be no room for renegotiation further down the line, even if somethings flagged on the survey. They've recently installed a new bathroom and kitchen and I would want to put in a new boiler anyway. The roof is in good nick (Dad is a roofer, came to the viewing with me). My uncle is also a builder and will be helping. A survey seems a little pointless and just an extra expense, especially since the vendor won't reduce the price anyway even if something needs repairing. I think the price is in line with similar properties so not really worried about getting a valuation. I know the lender will do one.
Would I be stupid to not get a survey? For £500-£800, it just doesn't seem worth it but maybe I'm wrong?
