This can help promote some goodwill with the tenant and add some nice value to their living situation.

Sounds good. Will

We try to shop at Goodwill, use Groupons, earn points/miles for free travel (travel is our priority!)

.$250-350..Goodwill...You will sleep better!!

You can get a tax deduction by donating to Salvation Army or Goodwill industries or Habitat for Humanity or any similar re-sale operation that is a charity.Otherwise you could be filling dumpsters and that will cost you money.

Then the dealer has good will of supporting the non-profit, they can put that in an ad (which also promotes the corp.)

If the Goodwill store is selling a comparable refrigerator for $150, then your basis for that refrigerator that cost you $1200 six years ago, is $150.

It's all good Will. :) 

Doing those thing cost time, money, good tenants, future goodwill (which is always needed sometime) and impact the investment more than can be calculated.The next issue between properties may be something were you need your neighbor's help to fully address. 

Nothing, no goodwill as she had already planned on moving.
