Me and my GF are looking for a house since about a month. A 1975 bungalow which got the whole relooking stuff well really catched our eyes but after the inspection, our inspector recommended that we call a drain specialist, which we did. Dude found a correction that needed to be made with the sewer, short term (about 3K to fix) and the original drain was broke at two places (2K to fix but 15K to replace the whole thing around the house.). Among a bunch of old pipes and electric outlets not up to the code. Dude flipped the house but not the important shit.
Then the dude was willing to drop the house 5K$ but hell, I thought it wasn't really productive to patch an end-of-life drain, broken at two spots which prevented us from looking the entire north side of the drain which potentially hide a third broken part. So in the end we made an offer that would cover both fixes and the guy just refused, not even an counter-offer. :|
We'll be probably looking for something newer now. There are some semi-detached that have enough space for what I'd like, too. My fear with those always are neighbor related, that's a coin flip. The middle wall will need to be properly sound proof, too.
