I have 63 units under contract for 4.2M. The property is extremely mismanaged and the tenants are quite undesirable. 20 of the units are affordable housing tenants and 5 of them are on a master lease with this company...

First off I use the BRRRR strategy and have done very well with it.

If there is a better strategy, please also comment. 

The type of business engagement and the level of interest in the counterparty or its assets influence the goals of a due diligence inquiry.For instance, a cordial agreement between a potential buyer and an experienced seller could provide the groundwork for a long-term alliance, whereas a hostile asset sale during bankruptcy would call for a different strategy.

You'll like also need reserves of at least 6-12 months worth of PITI (principal, interest, taxes and insurance.) 5+ units can require more down, but 25%-35% is common.

You hardly build any equity in your first year, it makes sense to refi only if the rate is substantially lower or if you can get rid of mortgage insurance.
