The rise in foreclosures has increased the demand for rental properties across the nation, and that trend will continue for some time. But aside from that new group of renters (people who have lost their homes) there is another demographic that remains constant. 40% of Americans earn under $35,000/year. Most of these people will be lifelong renters, who search for a decent rental accompanied by an attentive landlord. This segment of the rental market represents tremendous opportunity for smart investors, regardless of fluctuation in the economy.
