The savings can be used to buy another investment property that will give you at least neutral cash flow and you can still totally deduct the mortgage interest and state taxes on your investment properties instead of having those deductions limited in your single family home.

(financial things)..to include but not limited to any new leases or modification of existing leases together with rent rolls, with respect to borrower financial conditionThanks for your time

By using the BRRRR strategy I am limited to the amount of property I can purchase at one time (with the amount of cash I have saved), considering the rehab time and time frames I have to have the property before refinancing and taking that money to reinvest vs buying multiple SFR with conventional financing that need some work, but could be rehabbed within a couple months and the work is being done on multiple homes at once vs 1 multifamily.

Everyone has their own preferences, for both REI and Cars, but they are based on their own sets of criteria, limitations, and strengths...which you have not stated here...yet.

In my limited experience with portfolio loans, lenders typically use mostly the same criteria that a bank would use for traditional financing, but will allow a borrower to go over 10 loans if their finances justify it.

Some tenants will push your limits to see what they can get away with. 

For example call the water company and the power company to find the average monthly costs for the last six months.

In BC, there are limitation with percentages that a landlord can raise rent each year and once the lease is up it will roll month to month unless the tenant wants to resign another term. 

My time is very limited with my full-time job, and feel it might be best if I have all the information in one place and a resource along the way. 

Based on my very limited research the west side is probably the best, however many of the multi families are in the downtown area near the border and in less desirable areas.
