This approach not only helped resolve their issues smoothly but also built goodwill with local officials—making future projects easier to manage

Bringing the seller in on the deal not only gives them an opportunity to benefit from the upside of the flip but also positions you as a problem-solver, which can build trust and goodwill.

It’s a balancing act of controlling costs while also controlling risk of personal injury to your tenants and property visitors as well as maintaining goodwill with all involved at the properties. 

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

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. 

I'd be willing to do small projects for free to spread some goodwill.

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

Addressing their needs promptly and effectively fosters goodwill and loyalty.
