The Latino population in Las Vegas has increased dramatically over the last two decades. But Latino business ownership hasn't kept pace.

I bought a condo in Bozeman, Mont., 7 years ago using a 5/1 ARM. When the 5-year period ended, I let it roll over into a 1-year ARM because the rate went down from 4.5 to 3.25. Then, last year, I did the same -- only from 3.25 to 3 percent. Come March, the 1-year period will expire again and I wonder if I should let this happen again, since rates will probably be low. Or should I bite the bullet, pay approximately $2,500 in closing costs to lock in a low rate for 15 or 30 years, but make higher payments? (My payments are ridiculously low.)
