Hi Lattner - As I read TSB's info, you can have no more than $85,000/yr in total income. If you are borrowing with one other person, you can have income of no more than $85K/yr. total when you add both your salaries together. They want to use the program for one or two borrowers who make $85K or less. If you have more money than that, they figure you don't need the loan help as much.
Julie - I bet you're right. I hadn't thought of that. I pictured someone having to live in the same house for 15+ years.

But I'm sure you must be right. That's just a clause to keep people from moving out and renting the place while still paying on the loan.
