First time homebuyers can get a no doc loan with 10% down and credit scores near 700. Prior homeowners can get no doc loans with only 5% down with the same credit score. There are hundreds of different loan products to fit borrowers of almost any type. Each of these loans have different downpayment, credit score, and documentation requirements. As such, each carry different interest rates. No doc loans carry higher interest rates than "full" doc loans as the former represent a higher risk to the bank. No doc means that no income, asset, or employment information is being verified.

I never said that it was "difficult" to get a mortgage loan, but saying that the banks WANT to give away money is a little misleading. You would be more correct in saying that banks want to lend money to credit worthy borrowers. Both you and your wife have excellent credit scores which, to a bank, indicates that you are a good credit risk. I've seen thousands of credit reports and have lended millions of dollars over the course of my career. I assure you that the majority of the population do not fall into the "low risk" category that your scores put you in. I can not comment on the type of loan you have been approved for without knowing all of the factors being considered, but I am curious as to how they are qualifying you for a payment of approximately $1000+/month (depending on how much your taxes, HOA fees, and any mortgage insurance runs you) based on no income for you and only $10/hr for your wife. Banks do not count student loans as income (quite oppositely, they are debts). In any case, make sure you know what you are getting.
I do not want to discourage anyone from buying a home. Real estate is probably one of the wisest places to invest your money given the current state of the economy. I am in the process of finding a home in Baltimore to purchase for myself. I just wanted to offer some insight for those who are unfamiliar with mortgage financing. It's definitely not a "sign and drive" process.
