TheHusbandHalf and I bought a house built in 1915, but he had the knowledge to know all that was needed.
2 things to watch out for:
We use a septic tank out here, and the house was sold with the original septic system. All it was was 2 tiles in the ground next to the house and then the waste went back to the creek, about 600 feet behind our back lot line. We put in a leach field and a tank the size needed for 3 bedrooms.
We bought from the original owner, who never had any kids, so that septic system worked for them all these years.
There was no insulation in the attic or walls.
We bought this house because of location, original owner who we know loved her home, and except for a few necessary updates, it was like walking into 1920-30 or so. In our opinion, it is much better built than some of the new ones we have gone through.
