To be more specific about what i'm looking to do: My 1-2 year goal is to employ the BRRRR strategy with SFHs and Condos by buying distressed / highly undervalued properties that need work (preferably all-cash) in low crime areas with strong rental demand, renovate them within budget (again preferably all-cash) and get them rent ready before refinancing them at the highest ARV possible.

Firstly, never underestimate the power of having low leverage on your property.

I'm working with a company who owns a small, 19 unit, senior and low income apartment building.

-------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Outside of aesthetics, make sure you have cleaners, maintenance and turnaround worked out so you go in with a solid plan.

Getting a mother-in-low to co-sign is not the answer.

Since this four-plex is in my region, I will be the one taking care of maintenance and management while the investor won't have to worry about anything but to receive the money haha.Let's confirm a few things before you get questions from a bunch of other folks on the forum.How much of your own cash/equity are you planning to contribute/invest to this deal?

It allows you to take advantage of a low down payment loan.

Their dollar compensation is their free/reduced rent.If you have a lot of maintenance with landscaping or POHs then you hire them as an hourly employee.   

Maintenance, We had a pool so I know first hand, you really need daily work on a pool.
