The only catch is that you need to get an accurate scope of work with a contractor you trust before you purchase the house.  

I wouldn't fund all $50k+ of a project on CCs because that will catch up with you quickly.

Good catch Steve.

But the supply on their sites seems rather constricted compared to the MLS and biased towards SFH.My rather archaic alternative is to simply monitor Homesnap and Zillow closely with an Excel spreadsheet and hope I can catch deals as they go by and gather all of the other relevant information from other sources.

Another tip that helped me catch leaks is having the water company bill me monthly, instead of quarterly.

Everyday, I quickly analyze a few homes in my area to catch a great deal.

If things turn around in Calgary and things start going up again, I would consider picking up a flip or two and catching the rising tide, but it wouldn't be anything long term, just to add some cash in my pocket.

Airbnb / STR is illegal in most of Las Vegas, many HOAs don’t allow it (and they will report you to the city when, not if, they catch you), and in the few neighborhoods where you can do it, permits are required. 

We literally had appliances catching fire and shocking the tenants. 

@Sam T.I'm not a banker but I would imagine once you get one, maybe two LOCs, then the banks would catch on and start turning you down.
