Inflation? For $10,000 he is going to take a property that has been abandoned for years and make it livable?
I am not a finance guy but I know the on the ground realties of such a piece of property.
Broken water pipes, because the gas bill was not paid.
Drywall repairs, because the plumbers Had to rip it up to get at the pipes.
Non functional furnace/hot water heater.
Kicked in doors.
Broken windows.
Flooded basement. No one pays the electric bill. the sump pump stops working.
I could go on and on, but I think inflation is the lest of his problems.
