Don’t paint with too broad of a brush there.
Rehabbers would probably be called “flippers” because they don’t hold the property long, but they sure and take some dumps and turn them into nice domiciles for folks who need a house.
You're right, of course, but in the last 5 to 10 years, that hasn't helped most buyers who both need a house and can afford it.
The snowball effect of real estate fees and increased tax assesment is a fatal flaw in that argument. The get rich quick folk artificially increase the price of all available housing. Else how do you explain the outrageous prices of falling apart non-rehabs?
