Newblet, I wouldn’t fret too much about high interest rates. There’s a good chance you’ll be able to find some lender who will give you a loan with low initial payments, and then you can re-finance down the road when interest rates decline again.
Just make sure that the price of the home is something you can afford – not the monthly payments, the price. If you had to save all the money to buy the house, and you put all your savings to that purpose, how long would it take you? If it would take you 20 years, then you’re not leaving many options for retirement savings or other needs.
