This is extremely worrisome as there hasn't been anything on our end that changed, and this means that there is a shift in market conditions.

@Albert Johnson I recently did an “upgrade” ($10,000ish) for an extremely vocal tenant.

Almost everywhere, STRs are becoming extremely competitive.

It covers everything from the specific start and end dates, quiet hours, common space sharing, overnight guests, etc. 

The block where I have my property is very quiet.

Seems extremely high but maybe it’s typical? 

The one caveat I will add is that it is extremely location-dependent. 

The arv will be around $1,050,000 on the extremely low end.

I find data on free sites like Zillow extremely helpful for days on market for certain homes, and it allows you to sort by bedrooms to see how long a potential property may sit on the market at this moment (great for comping rent prices in the area as well)if I were to live in the property, I would take advantage of the FHA low down payment option to keep cash in my pocket for Reno costs  Hope this helps!

You can look to seller financing or other creative means if that is an option with the seller.Either way, I would say be careful if you do purchases below 100K that result in a loan below 100K, Options are severely limited and there is often an "interest rate penalty" if the loan is at this level and it is EXTREMELY challenging when the loan if below 75K.
