The buyer promptly disappeared, leaving us with a 13K code enforcement lien, as well as a house full of junk.

The numbers are only going to get you so far.The numbers won't tell you if your GC is going to flake out and disappear three weeks into this rehab, if this dubious person hired a trim carpenter who doesn't know how to cope inside corners, if your flooring guy's going to assure you that of course there's no problem with having vinyl flooring in the kitchen of a home that you intend to sell for over half a million dollars, if you have plans on replacing those Lowes bargain bin flushlights in the kitchen and hall with something else, if your drywall guy will eventually tell you that, sorry, he knows nothing about plaster repair in structures dating from the 1920s, if that ceiling in the living room is popcorn, painted popcorn, asbestos-laden old painted popcorn, or just a knockdown texture finish, why there is a washing machine in the kitchen, and the hits just keep on comin'...Get in the weeds of the rehab analysis, Alon.

My co-worker friend (who was about 8 months pregnant) was cooking downstairs when water came flooding through the light fixture, across the floor and into the dining room where they had just placed new laminate flooring.The "plumber friend" disappeared and my friend and her husband realized the value of owning (which they did not have) a water key to shut the water off at the curb meter.
