However, hauling away a truckload of items and cleaning beyond standard expectations could reasonably be charged to the tenant, as it goes beyond normal use.Goodwill Gesture: Since this tenant was great for 5.5 years—paying on time and caring for the property—you might consider waiving part of the cleaning cost as a goodwill gesture.

Quote from @Evan Ross: One of the most common mistakes I see with amateur landlords: attempting to build goodwill with their tenants.

There is absolutely no doubt that the business and all the business integration/goodwill of those operations are worth significantly more than just the 10 cabins on 2 acres of land. 

We would offer more of a budget-friendly option which could include FB marketplace/goodwill -Manages furnished rentals (STR/MTR) for investors.

Can't say what's hardest, too many moving parts but take care of your tenants and build that goodwill, pays off in spades.

Addressing their needs promptly and effectively fosters goodwill and loyalty.

The cost to buy a laundromat can vary widely depending on the size, location, condition of the equipment, and goodwill.

We'll lose money for 75-90 days but the new rent is market so some will stay and not forcing people that can't afford it to move in the middle of a very cold winter I think buys a tiny bit of good will and is the decent thing to do.

Fixing a leaky toilet, replacing a broken light fixture, etc. can create good will.

Thanks for sharing your experience, I'm sure it will help someone else in the future, so at least hopefully something good will come from it.
