Well, make the small ruin livable, get a batterypack that has solar panels so you have 220V were you need it on the land, make sure you can live in the small ruin, you will need that for when you are going to build the main house, get some all terrain tires on your car, look on flea markets from some good used tools, it saves you a lot of money, everything else you will handle it when you see it.
