If you buy now and mortgage rates don't change: You made a good move since home prices are projected to grow with time, so at least you beat rising home prices.

If you buy now and mortgage rates fall (as projected): You probably still made a good decision because you got the house before prices appreciated more. And you can always refinance your home later if rates are lower.

If you buy now and mortgage rates rise: If this happens you made a great decision because you bought before both the price of the home, and the mortgage rate went up.

Some lenders are offering FREE future refinancing, including transfer of escrow account.

I paid 13.5% interest on my first property back in 1978 and I did survive that - you can too.
