Before you list it, make a resolution to finish "just" the bathroom plumbing (or any other half way finished task) that can be buttoned up in less than 4 days. Do it, and see if that doesn't trigger you to do the next thing, and so on. Doing 5 little things might get you so close to finishing that you go ahead and actually finish. Alternately, edit your "to do" list into essential, worth doing, and maybe later. Do the essentials and go camping.
Honestly - there are lots of things that are far less expensive if you do them yourself... but you never actually get around to it. Pay someone to install a water heater or a converter, and have it DONE - finished and you're ready to do the next thing.
Enlist help... your wife and kids CAN learn the skills needed to do the work. Having a wrench holder, or someone to talk over how to best do a task can keep you motivated.
The closer to done you get, the faster it will be salable for a good price.
Today is a gift, that's why they call it the present.
