Now we also have tourism, the U.S. government/military, and State government (which gets at least 90% of its funding from OIL).

@Hailey Sexton It isn't hard to find rental properties in most major cities although choices can be slim November-April when tourism is high.

Because of the high mountains, nature, and skiing, most of the towns rely on tourism. 

. : )Also, in Hawaii at least, the Hawaii Tourism Authority keeps track of all sorts of visitor statistics like how many visitors came to the islands, which islands they stayed on, whether they stayed in hotels, condos, or with friends, whether their stay was for business, pleasure, blah blah blah.

Orlando International Airport (MCO) is very sizable (and currently undergoing a large expansion) and has many nonstops throughout the U.S. because of the tourism here.

So in my eyes, once the number of credit card defaults becomes significant this will probably mean more foreclosures are inbound.

Additionally, I don't have to worry about tenants boarding up windows when a Hurricane is inbound to prevent damage and expensive repairs.That said, I doubt renters are going to be swayed to rent based on having high end windows to potentially cut down on utility costs. 

I live in Yuma, AZ, and there's a tiny town across the border (Algodones, in Baja California, MX) that caters to the elderly with medical tourism.

In addition, our beautiful beaches and tourism are flourishing.  

You would think San Antonio would be lower in property taxes due to all the money that tourism brings in, as well as all the high taxes on hotels and other tourist things.
