My 2 cents in self storage is that you should really do your homework with current construction costs for this product type.

New construction is pretty expensive right now so I'm trying to run #'s to see if it makes sense.

You'll have to become an expert at finding and converting motivated sellers + an expert in analyzing deals (including construction and acquisition costs).If you want to eventually get into buy & holds, I'd start there... you can start with a low-down-payment owner-occupied househack, multi-family or other rental property deal.

I need to say up front that construction questions aren't my strongest skill set.  

If you're more interested in the in-fill scenario, maybe buying an old manufactured home on land and building a new spec home, then it's less the development issues above and more construction costs etc.

The idea that you are going to pull off a BRRR without owning a construction company or being a GC while using barley any of your own funds is more dangerous than lucrative.

The delays you refer to are pretty typical in the construction industry from my experience.

It is a solid brick building, but the replacement cost shot up due to the change in supply chain and construction costs. 

I was wondering if there was anyone on this feed experienced with Canadian permits and documentation that are required to proceed with getting a construction permit.

They bought the house as a new construction in 2016 from the builder. - The appraiser was present in person when he took the measurements.
