I'm focusing on Sec8 right now as it decreases the problem of someone moving out too quickly and not paying rent not saying it can't bring issues.

Wikipedia - https://en.wikipedia.org/wiki/...Both state and metro populations are increasing - Do not consider investing if the state or metro populations are static or decreasing.

Many markets are seeing YoY decreases in occupancy, and thus likely nightly rate as well. 

As @Eliott Elias mentioned, the LTV may decrease by 5%, but that may also depend on the borrower's experience with STR's.  

In recent months, the CPI has been stagnant or decreasing slowly despite the Feds aggressively pushing rates.

The prices might not be much better than Miami, but the STR demand is pretty good, and the prohibitive Airbnb regulations in most areas decreases the competition for those who can buy in the areas that are actually friendly to short term rentals.

Travel demand decreases and your occupancy and nightly rate decrease?

Especially with interest rates still increasing, would have to see a major decrease in home prices for it to make sense to buy and rent.  

Basically, if all the houses in the neighborhood do not have pools and the Subject property does have a pool, that may suggest the Subject pool is an over-improvement and may either be less desirable for that market, or in some cases, this can actually decrease the value of a house (not typically though).

I'd sure hope.Homeowners with adjustable-rate mortgages may benefit from declining housing services inflation, as their mortgage payments may decrease if interest rates fall.
