One of the details of that, in a nutshell, is that if no one is physically living on the land, even if there is something being developed there, anybody can "move-in" and begin living there.

Major damage to the sill plates would be much harder.

As has been pointed out the tenant can move out, damage the place and the value of the house can fall.

Termite damage allowed a lower ball figure and offered cash with no contingencies.

The bigger concern however, is the potential for damage when the washer malfunctions.

IMO a roof has NO ENHANCED VALUE for the simple reason that the bare minimum buyers want from a house is a ROOF OVER THEIR HEADS, and a house without a roof, or with a visibly damaged roof is unsellable.

Education is fine but losing all your money and damaging your credit while learning is a tough way to go.

I've done a lot of roofs in my day and the only one that cost close to $5K involved tearing off wood shingles, putting down plywood decking and radiant barrier and then shingling.If the roof is already leaking it's going to lead to damage to the roof decking, insulation, sheetrock and interior wood.Probably cannot adjust the price up for the roof as a roof over their heads is about the bare minimum that a buyer is looking for in a house!

Less about the physical mechanics and more about the how and why in terms of the RE assumptions.John Corey

It's been a looooong time ago, but back in the '80s in Houston I got my RE license (strictly as a way to get to physically attend the weekly RTC auctions).
