Simple furnishings bought used, a single bed, and dresser. 

Acquired a double lot for $112k after resolving title issues and paid $360k for construction, creating a 6-bed, 5-bath house designed for co-living or multi-gen use.

I have 2 large cabins (2,000 and 2,500 sq ft) I'm holding and another 2 bed 1,500 sq ft cabin just about done and another two that are under construction for holds.

If you're going to work with contractors, collect rent from tenants, or try to bed the hot chick at the bar, you better learn to recognize warning signs and get out early. 

Or find a property that is under-utilized or has below market rents.Otherwise, you could also do the OPPOSITE of the great advice from @Jonathan Greene and buy a property with multi-bed units or live in the larger unit and rent out the smaller unit - while getting a roommate(s).

I had a realtor ask if I had any other 2/3 bedrooms so happy to connect you with them if you have a 2/3 bed?

These are all going to be 2 bed 1 bath a little less than 700 sq ft. 

I am looking at a 4 bed 2.5 bath property in Pfugerville, TX that I am planning to rent out as a co-living space (rent by the room on Padsplit).

I generally rule out most single family homes as viable rentals, as prices are pretty high relative to rents, so aside from some downtown neighborhoods, typically you do not find large areas of single family rental neighborhoods (a median sale price on a 3 bed, 2 bath home so far this year in Dane County on MLS sales data is at $430k).
