Let's see, I would have to add a a/c, paint it and strip the wall paper and paint. The floors, well, I can't tell if that is real wood, if it is restore, if not replace to real wood. The floors with linoleum--that would have to come up and either restore wood underneath or replace to wood. Of course, kitchen appliances. And the garage door would need to be replaced or removed. It would be important to me to keep it as original as possible.
The houses local to me that are in the historic district, all have to be redone with the era the house was built in mind. We knew a young couple that bought one and just replacing the shoe molding took months because they had to find replica of the original in the house. But they did all the work themselves and tripled their money.
