As mentioned the main downside to using a SDIRA to purchase properties is you get no tax benefit upside (depreciation) and have to pay taxes on UDFI.

This helps you identify which factors drive the best returns and make confident, informed decisions.It’s also important to test your numbers with scenarios like higher vacancies, unexpected expenses, interest rate changes, or rent adjustments over the years.

Mainly how or if you offer them at your STR.

That will play a factor for qualifying.

The fact its in a landbank tells me that it was taken back for some reason, which tells me its likely not a high commercial demand for development, but I could be wrong.If it is "on the main drag" in this town then I'd think doing a new build home to do a targeted and intentional air bnb would be the best bet. 

Once again, the loss of the compounding factor by concentrating on my personal home rather than an investment was significant. 

My main focus is Class B and maybe some C+ properties around NE Columbus, as well as outside 270 from the North to the east side.

One main regulation I find in Ontario Residencial Tenancy Act section 134 (3) states you cannot make a profit in subletting.

And in REI, correction happens when inventory increases among other factors.

I know that my COC my be lower, etc but my main concern since its my first property is being cash flow positive.
