I think its the wrong question to start with.


Houes come in a range of conditions and lifespans irrsepective of when
they are put up.

Ther are some truisms around to illusdtate


(i) Old houses that have stood for 300+ years are probably, lucky, well
maintained, or well built.

(ii) EVERY house needs a minor upgrade every 15 years, and a major one
(up to 30% of the cost of replacement) every 60 years. Its also true to
say that older woners mend and make do to take em up to the 60 year
mark: When they die, its usually time for a massive gutting and
modernisation.

(iii) A brilliant house in a crap location is worth less than a crap
house in a brilliant location.


None of thes issues really answers the OP's question,. becaue its the
wrong question. There are good and bad examples of both.

The question you should be asking is, whether THIS house, at a price I
can get it, represents good value for money to ME, with my (nonexistent?
or not?) DIY skills.
