This is what a $350,000 house in San Francisco looks like

[Spitfire of ATJ]

43. The foundation is fine. Someone did the porch on the cheap....

Looks like 2x4s and plywood. A lot of older homes lose their wrap around front porch in snowy climates. These days it's worth a full rebuild since we have products that can seal against the elements. I would coat each board prior to assembly.

The main Issue I'd have with a home like this is insulation. I've seen where people slap up insulation outside and then cover the place in vinyl siding that blows down the street with the first storm. I'd go the other way and strip the inside.

I'd also want forced air rather than radiators so central air could be installed. Then there's the plumbing. Many of these older homes only had one bathroom too. All of the electrical including the fusebox needs to be updated. I've seen vintage wiring where they keep the cloth covered wiring separated by hammered ceramic insulators in the attic. Many cities insist all of that has to be done by obtaining building permits and hiring a licensed contractor and then it has to pass inspection.

It could become quite a money pit.
