We have a house built in the early 50's. I have lived in one built in 1900 as well as one that was under 10 yrs old. DH spent several years in a house built in the mid 1800's. There was LOTS of renovation to be done on that one! ;)

What problems have you discovered in the old house you bought?

Here is an article written by a previous home inspector who said the following about old houses. Do any of these issues ring a bell with you?

"As long as there have been homes, there have been home repairs. If you know the age of your home however, problems common to homes built in that era that can be avoided.

While home construction has changed quite dramatically over the years, every era of home construction had its strengths and weaknesses. For example, old homes offer character and charm that is rarely reproduced in modern construction. But, old homes are also drafty and leaky. Newer homes might offer energy efficiency but they go up so quickly that workmanship often falls by the wayside. Any way you look at it, the home repairs add up........!"
