Vacant homes are often the result of government regulation.Here is a factcheck. Technically if you'd like it says the original claim was false but the underlying fact is true.
FACT CHECK: Are There More Than 633,000 Homeless People And 13.9 Million Vacant Homes In The US?
Perhaps a fair criticism of my statement. However in defense of it prior to the 1920's the most common job was subsistence farming in the US. Tenant farmers after slavery was abolished was the replacement of that "lost resource". The treatment of these people were not at an acceptable level. Many that were black and tenant farmers had it almost if not equally worse than when they were enslaved due to the quick and effective work of the antebellum of the south.
The late 1800's in Europe are the first apartments though the experiences are not necessarily equivalent to today's system. The 1920 in the US is when we started contracted renting as we see it today.
When homeowners get the boot, it's a long process for lenders
to be able to sell the property with clear title. They could rent
them out in the meantime, but that poses some risk, & banks
aren't interested in complicating the process.
If they homes are livable, they do eventually get sold. So there's
nothing that stays off the market permanently. This problem
resulted from the crash that began in 2001. When the Twin
Towers fell, many businesses close or contracted, leaving
people with less income. It reached a noticeable climax
about half a decade later when lenders collapsed.
I do some mortgage lending, & I only lend to people who
I know well, & whose businesses I know well. The last
thing in the world I want is to take over a property by
foreclosure.
