hi thanks for sharing!
I think that it's fair enough and somewhat understandable if a homeowner gets used to their home e.g. "vendors who have lived somewhere a long time get used to odd or old-fashioned things and just don't see them. I'm living in a doer-upper and I've got so used to seeing half-stripped walls and bits of bare brick here and there waiting for the plasterer to find the next slot that I don't even see them now"
But it's not "understandable" if you think you can sell it for a bomb.
a house that's not "done up" to me includes safe re-wiring, good plumping, and a general reno (which means taking it from poor quality to high(er) quality.) The value of this house would reflect that modernisation.
Old house that haven't been touched for 30 years are currently money pits -this type of house is deemed unmodernised, i.e. it usually isn't in a liveable state...
Regardless of how little the homeowner "sees" the issues (or has actually ignored them), it doesn't make the house a quality house. It might even make it unsafe. If it's not a quality house, it's not worth the same as a home that has had that work done. And even in today's market, those "done up" houses are still over-priced.
A house that requires a reno should be cheaper, to take into consideration all the work need doing, materials, time and labour etc. As the pp states, some people like to buy fixer uppers so they know the quality of work that's gone into it, and that's fine, I would feel the same. But I and many buyers wouldn't buy a property that's the same "value" as other houses that have been essentially, "modernised" (regardless of decor taste). Otherwise, if you do and then spend a bomb on the reno work, you've got a house that costs way more than the current market value, and in a market that's going down down down and is essentially a buyer's market, it's madness to purchase now due to risk of negative equity and all sorts.
if someone has the budget and doesn't care about the reno costs, then that's fine too. but most buyers aren't in that category.
