You need to spread the risk out over a large number of people because you will win some and you will loose some.

If one roommate moves out unexpectedly or looses a job, either one of them needs to be able to handle the rent amount for some period of time.  

There are trained service dogs for people who have seizures, people with diabetes, people who are wheel chair bound. 

In amateur tennis, 80% of the time you "score" when the other person makes a mistake (hits the net on a serve, hits the ball out of bounds etc.).  

Are they bound by the same mortgage regulations as if it were an RRSP (forced CMHC on non-arms-length and max 80%LTV on arms length)?

And just because a place meets the "2% rule" doesn't mean you're not going to loose money on it for some reason.Yes, what I've learned on BP has changed my investment strategy.

Just rough estimating based on your numbers here's what I get.50K x 70% = 35K (using 70% rule of thumb)35K - 32K = 3K (less repairs)3K - 5.5K = -2.5K  (less back taxes)Thus using the 70% rule, you loose money.

I agree they'd make all of our lives much easier (and probably less safe), but I'm afraid that's out of bounds with the type of project I'm capable of.

If you enjoy what you are doing, you are bound to be more successful at it. 

your money is loosing value in that time frame.
