Well, noooo. Actually, we *had* to move. Staying in the house forever was never an option. When we moved to Arizona we had three choices: we could wait 6+ months for an opening then move into on-post housing, we could rent a house for $1200 a month (plus utilities), or we could buy. We choose to buy, invest in the house and property, then sell and actually make some money. Getting an ARM freed up more money to fix up the place. With the savings, we put in two decks, an extra out building and remodeled the bathroom. (The kitchen and landscaping cost even more.)
Once we moved to a house that we *could* stay in forever, we got a 15 year fixed. *Now* we have the security of being able to stay in a house forever. (Yeay!)
I know, I was trying to drive the point home that there are lots of cases where an ARM makes sense.
