Yeah, lots of possible issues. We looked intensively for a year (out every weekend, I was running a big spreadsheet with options appraisal in) before settling on the place we eventually bought....... some of the things we encountered during the househunting phase:
(1) What was actually being sold was not what the vendor had said was being sold (they omitted to mention that the large parking and access area was a separate piece of land that they were not selling).
We checked every property we were interested in on the Land Registry after that, it's a worthwhile few quid. Allowed us to ask some searching questions of estate agents.....
(2) Non-mains water supply in a location to which there was no right of access.
(3) Mobile phone mast/electriciy pylon very close by.
(4) Indecisive vendor. So you make an offer then the chaos of "do we want to really sell or not" involving a big family arguing commences.....
(5) Something a bit nasty nearby. (Industrial plant, smelly landfill etc etc etc). Google maps and Streetview is your friend.
(6) Property down a private access road of over a mile, via a bridge over a river, and the other 3 nearby properties are all holiday lets with absent owner. Worrying maintenance liability there....
(7) No modern facilities in terms of no central heating and no electricity grid connectivity
(8) Access is via a lane of dubious rights, or no vehicular access at all.
(9) Property needs renovation or extension but the last owner annoyed the Planners so you will be struggling
(10) Part completed renovation but vendor hasn't bothered talking to Building Control and it's well on.
(11) Tall masonry viaduct pier from a closed railway in the garden, over 150 years old, buddleia has a good hold near the top, unknown ownership/liability.
(12) Agricultural tie: The property was under covenant and could only be sold to someone working in the area in agriculture.
All off those things we found and walked away from, or didn't even go and look even though it looked attractive for the price. Even without that, some places we viewed just had bad vibes so were a "no" within the first 5 minutes.
(Haven't even mentioned internet connectivity as you can get Starlink these days...... or the usuals like flood risk.... but don't forget risk of hillside fires too)
The place we finally bought didn't have any of those but needed major renovation, we have a full structural survey and even then we found a few more nasties. We took the place back to bare shell- walls and roof, rebuilt the chimneys, new floors, ceiling, internal boarding, full rewire etc. Plus the extension being done. But at least we know what we have now it's been rebuilt. The advantage of a known "project" is that if you strip it right back to a shell, you know what you have and what you put back...... but it ain't a cheap option.
Good luck!
