Hi Mark, there are a number of things you could do:
- You could finance the purchase through a bank, with between 20 to 30% down, depending on many factors like your income and credit score. You could also take out a loan for renovations, but I would check what banks do that.
- You could ask your grandfather for owner financing and that is preferable because regardless of your financial situation you could get a loan for buying the house + cost of building a house/renovating. Also you could work out a payment plan with him so you don't break the bank on day 1. As you may know, when you buy a property through financing with a bank, you've got mortgage payments to pay starting month 1, even though you have not yet sold the house. Add to that real estate taxes. So there is a holding cost while you do flip to the property that are not negligible if your cash reserves are low.
I am sure other members will give you other options as well, but yes, it is feasible.
