I would want to get a statement from the father and son stating anything left behind after closing may be disposed of, and has no value, preferably signed and notarized  

You have to hire a moving company to move the items to storage for the tenant I think for a period of time before you can dispose of them.

To use a tiny example, I've told her upfront that if a garbage disposal looks like it's broken, replace it.

The contract itself states the following:"Specifications: Proposed CostRoofRemove & dispose of the existing roof, if additional layers are found they will be removed at $50.00/sq.Inspect current roof deck, if replacement is needed it will be completed at $1.65/s.f.Install 1⁄2” fiber board to the entire roof deck using screws and platesInstall .060 TPO to the roof with all needed flashings and trimsInstall perimeter metal with all needed flashingsProposed Cost: $3,300"I guess my question is, what options do I have at this point?

Perhaps a better way to approach this is to arrange the future sale of an undivided interest in your property, you can sell someone say 25% of your ownership interests, then dispose of the property together.

In addition to Fannie & Freddie, there are many other buyers of mortgages, in various forms.When a foreclosure is needed, its often the servicer that performs the process, takes the property and then hands it over to the investor for disposal.

I do work full time and don't have enough disposable income to set aside for an investment.

Grabbed it by the tail and consulted with animal control about where to dispose of it.

If you still have one that you are already depreciating you may accelerate the remaining cost between what you dispose of it for and the remaing basis.

The guy that paints for me uses trays with a disposable tray insert.
