So will more inventory hit the market in 2025, probably, but the key is, is it quality STR inventory hitting the market. 

Buy quality not quantity.

I'd also recommend these two books by Avery CarlSmarter Short-Term RentalsShort-Term Rentals, Long-Term WealthI've been doing a lot of the BiggerPockets books as audio books while I drive instead of just my usual podcasts when I really want to drill down and learn a specific topic and I'm loving it so far.

For example, if a 1,600 sq ft main house is appraised at $100 sq/ft, what could I expect a 600 sq ft ADU of similar build quality to be appraised for?  

You will constantly hear of  shortcuts during construction and the conscientious decision to use lower quality materials during the renovation. 

Quality VAs can do anything.

No formula can be accurate across the board because even “cookie cutter” properties next store to each other differ as to view, location to the street, topography of the land, lot size, physical condition of the property, past remodeling, quality of the mechanical systems, sunlight, utility bills, past use, etc.  

Your returns in investing ultimately come from exchanging terminally abundant goods (fiat dollars, debt/future fiat dollars) for terminally scarce goods (high quality, supply constrained real estate).Selling to go into cash isn’t of interest unless I have a short term need for that cash or am funding another purchase.

And I put all quality materials and high end finishes throughout.

Hey @Ashley Wong,I don’t have much insight into Columbus or Tulsa, but I run a turnkey provider in Huntsville and can vouch for the area—for two reasons.First, Huntsville’s strong demographic headwinds have led to steady and sustainable population growth (+20% in the last decade), while the city’s abundance of high-quality STEM jobs—brought to the area by industry heavyweights like Dynetics, Boeing, FBI, Redstone Arsenal, Blue Origin, and others—have attracted numerous well-heeled millennial renters.
