I could also Airbnb it as an eco house as I will make sure air quality is optimal and buy organic mattresses but I'm not sure if Hagerstown would be a potential vacation destination.

Here's a few online sources on the matter:The fact of the matter is, the landlord cannot “double-dip,” collecting full rent from one tenant, who has vacated, and collecting again from the new tenant.From: https://corealestateattorneys.com/breaking-a-colorado-residential-lease/In Colorado, landlords are usually required to mitigate damages if you move out of your rental before the lease is up.

If the fees are defined as "additional rent" in the lease, the LL can deliver a 3 day notice to pay or vacate, but if they are not defined as "additional rent", deliver a 7 day notice to cure by paying the fees. 

Vacation rental?  

it looks like a hopless situation for me.I had all of my life savings put in Yucca Vally short term rentals In  early 2022. got 4 nice villas at 20% equity. then 2 things happened: rates went up and demand for vacation rentals in that location went WAY down. 

I have brokers in various states where vacation homes run into deductible issues, HOA reserve issues, litigation, just to name a few examples.

My team and I dive deep into market analytics to provide our clients with comprehensive reports that guide them in making informed, data-driven choices when entering new markets and setting up their vacation rentals.Moreover, we prioritize a human-centric approach in our designs, ensuring that not only are the aesthetics on point, but the functionality and comfort lead to happy guests and consistently stellar reviews.

The majority of our STR investors and vacation rental buyer clients ask or elect to close their acquisition in an LLC. 

Is there a clause in your lease that specifies a particular notice period for vacating the premises?

HelloWe travelled to tarpon springs with my wife in March and really loved the area and the parks/beaches there.We are thinking about buying a vacation house/ investment property there.
