How your housing costs change when you relocate. Based on 2026 data with 10% down, 6.5% rate, 30-year fixed.
Your housing costs will decrease by approximately $372 per month ($4,464/year) when you move from Montana to Arizona.
If you sell your median-priced Montana home ($430K) and buy in Arizona ($380K):
Your Montana equity covers the 20% down payment on a median Arizona home with $53K left over. That surplus can cover closing costs, moving expenses, or go into savings.
Over 10 years, this move saves you approximately $45K in housing costs alone.
Your dollar stretches further in Arizona. The median home costs 12% less than in Montana, which translates to a $50K difference in purchase price. This means a smaller loan, a lower monthly payment, and less total interest paid over the life of your mortgage.
When you buy in Arizona, expect about $6K in closing costs (1.6% of purchase price). Arizona has no transfer tax, which helps keep your upfront costs lower. Budget for this amount on top of your down payment.
