I’m also open to exploring short-term rentals, private lending, or passive investing in funds—anything that maximizes returns while keeping risk and time commitments manageable.For context, I’d consider leaving my job if this could become a full-time venture that surpasses my current compensation (low-mid six figures).

I'll see if I can use some of this because I get almost no Airbnb bookings unless I drop price way low.

So if you discount a small amount to get rolling, that is something that can work, but don't want to stay low for long.You will start to get the dregs staying at your place and they can do some real damage to the place.

It's interesting because of the low start up capital and potential for higher returns.

Most of the stuff you can get at Home Depot or Lowes and get it the next day, so no delays once you decide on something. 

You might be able to find a lower price point per unit than I’m at but it’s a LOT MORE WORK to have low quality properties as opposed to nicer ones.

OKC has alot of opportunity mainly because of its low level of enforcement of housing codes, strong landlord laws and conservative judges in eviction court.

Yup for most of the Usonians the loads of wood used is cost prohibitive now and hard to source.However, I thought about this one as an example of a build with simple materials (steel and concrete block) that are not in themselves expensive to source that can achieve a beautoful design (with great effort of course by designer and builder) at low cost and scale.

@Bonnie Low I was not including debt as I want to know how a cash buyer would look at the deal.

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).
