I just did a quick search of the area and there appears to be an ample supply of properties with an average rent of approximately $1.10/SF.

And make sure you live in that 1st house so you're close to and can address problems as soon as they appear. 

Appears the guests may have left the faucet "on" when the pipes were frozen and when no water came out, forgot to turn it "off".What may have caused the overflow of the sink is maybe the drain lines were also frozen?

.-- The biggest indicator of turning public sentiment was just last month, in December, when voters in Woodland Park approved a ban on vacation rentals that also appears to NOT grandfather in existing licensed properties. 

Unless the medical condition meets the state criteria for early termination and that the medical notice does not appear to suggest that, you cannot terminate the lease outright/immediately but that you will begin to market the property for rental and upon securing an acceptable tenant, the lease can be terminated pending a satisfactory property walkthrough indicating no damages. 

If they are up for renewal and you elect to non renew them you must stop accepting funds from the occupants after the lease expires (accepting rent after the lease expires may make it appear you have a tenancy at will agreement). 

The only issue appears to be the missing breakers and it being turned off by the bank.

Quote from @Arthur Crum: It appears you may know something I don't.

We had to bring the 1925 house to 2023 code which involved un-installing 26 windows that were already nicely installed (in appearance) in the house, reframing them to 2023 standards (at the time) which also involved strapping the bottom of the wood framing with metal straps (mind you this all after we had already completed the inside renovation).  

-It doesn't appear you are contributing any of the equity.
