Some have sealed batteries and some are replaceable.

For a Mid-term rental, I would say furnishing it with the cheapest but most durable furniture possible because of the frequent turnover.

Cheap curtains hung up on the first floor, a welcome mat, lights on a timer, battery operated fake candles on a timer, big size 11 men's shoes and big men's jacket hung by the front door, two empty dog bowls, a tie out in the back yard (for a dog), fan on a timer, foldable table and chairs with a tablecloth and centerpiece, and radio playing on a timer.  

This included installing new tile flooring at the front of the house to enhance curb appeal, upgrading the electrical panels for safety and efficiency, and putting on a new roof to ensure long-term durability.

You need to make it durable.

Initially I wanted to use vinyl snap together flooring since it is pretty durable and I have worked with it before.

Batteries go dead and you can;t get in.

I agree with the need of a furnace.Most mountain cabins have hot tubs.Emergency generators aren't cheap, but great to have during a sustained power outage.I've thought a battery backup system might be a good compromise.

Replacing old or worn-out flooring with modern, durable options like hardwood, laminate, or high-quality tile can make a big difference.

Durable goods like fridges, cars, and houses give us more control over our time and resources.
