- job losses
- mat leave
- have kids (kids cost money -- many people don't seem to appreciate that)
- ppl just manage money badly (I mean, to get by on a maxed out mortgage means you have to be VERY GOOD with your money -- then again, if you are VERY GOOD with your money, you probably wouldn't max out the mortgage)
- vacancy in basement suite
- rents in basement suite not as expected
