Hot to Know your Approx Max Mortgage before talking to anybody: Just take the time to write down first all your monthly expenses. Once you got everything, just take that amount from your NET monthly income. Let's say that, for the sake of this example, after you paid all your expenses you still have $2,000. Let's pretend an average Property taxes of $200 and a condo fee or utilities of $400. Then you still have $1400. Considering an interest rate of 2.4% this means that you can afford a $350,000 mortgage. (At least to live "comfortably"). It doesn't matter if your bank gives you more. That should be your limit.
