Owning has advantages that LL does not such as no vacancy, typically lower maintenance/cap ex versus being occupied by tenants, and often property tax breaks. 

I mainly bought it for the land, do not intend to rent it out for cash flow or what not.It is currently occupied by the previous owner.

Bryson: No the property is turnkey and currently tenant occupied.

It's not like a REO auction or tenant occupied property. 

And when you buy a 2-4 unit you can use 75% of the rent that the appraiser says will bring in on the units you will not be occupying.

This vary heavily town to town. 20% down is great if buying strictly as investment but if you have a way of owner occupying I would explore that route and apply the 20% down to increasing value of property and instead using low money down loan. 

Hopefully the current occupied units are paying every month.

Hi Jaycee,The owners occupy two of the 5 units. 

The property has 6 units with 5 veteran tenants currently occupying the place.

I want to know whether it would work legally for me to buy a home and occupy it for 6 months and then relocate for the maximum time of two years and then return to the property a my primary residence.
