You can probably call the water dept and get usage numbers for the last couple of years.

Under the TCJA which was signed into law in December 2017, net operating losses were no longer eligible to be carried back, and their usage, when carried forward, was limited to 80% of taxable income.

But if you already have a pro account and unlimited usage of the calculator, then maybe you don't need the 4 square

More water consumption, more electric consumption, in one property I even include internet and cable which I expect the internet to exceed the 2TB usage cap if the tenants are Netflix and chilling 24/7.I have not yet reached out to my tenants about rent yet. 

Similar to a hotel throttling internet usage, does anyone know a device or data carrier that offers a mifi/hotspot with the ability to throttle data by the day?

Since I myself will be renting from him, would it inappropriate to ask him for advice and/or seek out a mentorship from him? 

Unless you can run a sub-meter to isolate usage, plan on paying for it & including it in the rent.

It sounds like Canadian financing, particularly government backed options have some big differences to US agencies.  

Any usage against that credit will count against your DTI, so just figure that in when you refi :)

The tenants are responsible for their electricity usage.
