I suggest contacting an RE attorney who can assess your options.

As properties have begun to be paid off for me, that few hundred a month becomes a rounding error as real wealth and options become available to you. 

Let me know what options you find

For STR, AirDNA is the most popular option of course, but the pricing model per city is rough (if it's still like that).

There are options you can invest in such as oil and gas, datacenters etc. that typically provide significant depreciation.

If you need any help running those numbers or figuring out your options, don’t hesitate to reach out!

Also I hear PriceLabs does dynamic pricing, and but I  see AirBnb also has dynamic pricing option as well.

Then you can take them off-site yourself so you have time until the next changeover or create another option for the cleaners that they go back and finish the sheets and store them so their changeovers will be easier as well.

Fortunately at my rate they have some cash flow and good appreciation.The rates make it rare that the brrrr is the best option available.  

Difficult to defend places -- hillsides with limited transportation options, etc. -- won't be allowed to rebuild at all.
