I just bought a 6 unit building where rents were under market value by $350-$650 which for one unit was almost 45% under market rent.

I come from the world of 100-500 unit properties where this was not the case and every property had it's own separate accounts that we controlled as the owners, but now having been owning and managing 1-80 unit properties for 4+ years, trust accounting is the best way to do it. 

If you have enough unit it will make sense to have cleaner on your payroll but to starting off, most common sense is to find a very high quality, reliable cleaner that works with your budget.

Given that you're already in it for 6 months and close to getting it rent-ready, it might be worth holding onto it and renting both units out, which could help offset your mortgage costs.

(This HOA was not FHA approved, but now even single-unit "spot approval" is no longer possible.)

This criteria is for 1-4 and 5-8 unit programs.

@Kristee BadetHouse hacking involves living in a multi-unit property and renting out others, potentially offsetting mortgage costs and allowing savings for a personal home.

This criteria is for 1-4 and 5-8 unit programs.

For example in many jurisdictions I can STR units in a duplex but cannot STR an ADU (some jurisdictions will let you STR if you owner occupy).
