The lease reads: "RENT: TENANT Agrees to pay the monthly rent amount of $_____.00 plus any applicable sales tax as rent on the 10th day of each month in advance without demand at (NAME OF COMPANY), (ADDRESS OF COMPANY). ...  

@Jay Hinrichs is spot on about living in Vancouver with no sales tax as well.

This allowed me to focus mostly on cash flowing properties, then the area, then tax as an add on.

@Shay Sherbotseli The tax a withholding on the gross sale price of the home.

I read somewhere I could 1031 the portion of the property that I’m renting (ADU), and pay capital gains tax as normal on the portion I’m living in?

A 1031 delays the tax, a 121 avoids the tax. 

In CT, when a house is sold, the state and town charge the seller a conveyance tax,   a percentage of  the sales price of the house.   

What sucks is we used to live there for 10 years and paid income tax as a resident, but that is a wash now.

This is known as a Roth Conversion, which does trigger tax as you are moving from pre-tax, to post tax Roth.  

I've been reading quite a bit about corporation vs personal ownership in canada, and i think corporation makes a lot of sense, especially because i plan on expanding eventually to 100+ doors. the corporation just seems like a much better deal for paying as little tax as possible. however, i'm concerned that starting out i won't be able to get any loans, because my corporation will be new with no credit history. i plan on starting with tri/quad/quintuplexes and then working up to larger buildings. does anyone know if it will be difficult to find lenders for these types of buildings as a corporation in canada?
