In the markets I shop, there are plenty of properties that will cost around the 80k mark total (including rehab).

Anyone who instead attempts to buy me Coffee so they can sit down and "Pick My Brain" is immediately placed on the "I hate this MF list."

I pulled a list of tax delinquent properties in my area.

I feel like Cpt Obvious on this point but for some reason, people buy into his ever-expanding list of things he panders for profit. 

I currently have one property listed on Airbnb.

Utilize online platforms, real e­state listings, and work with local real estate­ agents to search for potential prope­rties.

I considered SFH where I'd rent out all the rooms and keep one to myself, but this seems risky since I'll realistically be away for months at a time and couldn't manage the unit/other tenants.Then I came across some listings that appear to be hotel rooms for sale, with basically the facilities I need (a bed, toilet, kitchen), a price point I can handle (270-500k$, I'd do 20% down), and fairly high HOAs (~1500$/m?).

Does this mean there is no downside to listing it for the maximum price of $4313 per month since the tenant would likely be paying the same amount no matter where they chose to live?

If you're unable or don't want to list them as an STR. 

I would also shop around, see if other property managers can give you similar or greater service value for the same or better price.
