I'm not talking about government assisted housing.
When a landlord has to pay $1,500 a month just to keep the property active, he has to charge more than that before he sees one cent in profit. That includes taxes and regulatory compliance costs.
When the business costs are lower, he would be able to charge less and thus keep his units occupied.
Vacant and idle units turn zero profit.
When I say, "low cost" it has nothing whatsoever to do with the government.
