I do my own property management to keep my expenses low. 

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.

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).

Across the board, the worse the neighborhood, the better the cash flow, the better the neighborhood, the trade off for tenants base, better schools, low crime, etc etc.

In the one house that I still have some existing, it's only on an overhead light circuit with no insulation around it, and I minimize the load on the circuit by using only low voltage LED lights. 

If I was the buyer's broker, I would have checked myself to protect my client.If they had, then they would have found out it was not a three family.Its a valid point.In NM, our zoning / city doesn't post # of units publicly, only high density residential or low density. 

The low purchase price, combined with an established market demand, made this an ideal transaction for a fast turnaround and profitable outcome.

1) I am wondering if it's doable to manage a condo/town house with tenants when I am out of state seasonal 9 months per year. 

You'll be able to meet seasoned investors that can direct you in the right direction.

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).
