A common question :
How much per month would it cost me if I bought a $250,000 place.
To give yourself a good idea visit my mortgage calculator.
Simply fill out the price of the property you are looking at, a interest rate (4 or 5% to be safe), the duration of your mortgage ie 30 years, if there are any condo fees, annual taxes and click submit. Condo fees and taxes can be found directly on the listing you are looking at.
