The first I still owe $150,000, second I took out of $150,000, and now I buy a third home worth let’s say $400,000 and use the $150,000 I got from cashout-refinance, as a Down Payment for the one Im buying worth $400,000 would I really get the extra $250,000 for the 3rd Mortgage or no???

Did you run it through the bigger pockets calculator? 

– monthly rent has to cover all expenses on the property 100% plus we usually charge extra 200-300 per month for the rent credit4) Does anyone know a good real estate lawyer in Calgary that may specialize in these?

I've been using the Bigger Pockets calculator religious to tally up what is the highest I'm willing to pay.
