Is buying a new owner occupied 2-4 unit multifamily property every year using 3-5% down payments a good strategy to scale?

Now assume each unit is occupied by 1 person.

Most credit unions do not help with non-owner occupied properties. 

For an owner-occupied property with 5% down, consider a conventional loan with a renovation option like Fannie Mae  or Freddie Mac.

We actually keep marketing your property and accepting back up applicants until your property is actually occupied.

Waco is a great rental market because there are so many blue collar jobs that provide consistent demand for housing (I have heard that 80% of homes in Waco-proper are non owner occupied) but there is a lack of white collar jobs that would keep Baylor graduates here or bring working professionals from Austin/Dallas. 

We ended up buying one house to turn into a vacation rental and the two other options were one- a stand alone commercial building and two- a ground floor unit (currently occupied with a tenant for another 3 years) of a building that is in the process of being turned into condos. 

4-Plex details: -currently occupied-estimated sale price 265k-ARV 400k, and 4k/mth in rentBackground on me: -I have an LLC-I own 4 single family rentals-each has around 70k + in equity-all cash flow well -credit is 800+ with adequate income.

Does their collective business occupy one of the spaces in the building? 

House A has a lower (but still high) wind storm deductible at 1%, while house B has a 5% deductible, and no one is occupying it as it was just closed.
