Second homes are a big part of the Arizona real estate market.

… the sheer size of the baby boom generation means sustained growth in the second-home market with the number of homes forecast to grow by 2 million units in the next 10 years.

Of the 43 million American home owners aged 50 and over, only 15 percent also own a second home. Perceptions of a growing market are largely ” anecdotal,” according to the study, which shows the rate of second-home ownership among 50- to 60-year olds relatively flat over the 12 years from 1992 to 2004.
