HI Hernan,You can always start off by house hacking meaning you live in one UNIT or ROOM and renting out the other vacant units/rooms to offset your monthly mortgage payment.There are several ways to run and make sure you are maximizing your rental income while keeping your living expense as low as possible.

Many people who got involved in the STR space are actually offloading these units as they cannot get the proper zoning or licensing. 

Presently, we reside on the bottom floor while renting out the top unit.

If you have not already used it, you can do an FHA loan with 3.5% down and buy up to 4 units.

It's 25 units, off-market (we are direct to seller on it) and is a value add opportunity.

@Marty HowieYes people are still investing, at least in residential 1-4 units. 

I am in the middle of turning over a unit and I really didn't want to replace the door. 

So I have a 2 story duplex in Houston, TX and each unit has a balcony.

Has any one converted an SRO to a standard multi unit building?

Since you do have 60 acres I feel like you could probably build way more units if you go through a rezone process.
