The rent has gone up so much that it has priced out a lot of the elderly and low income workers in the town.

So in conclusion,,if doing this make GOOD neighborhood friends and help them out,,,scoop and mow for them if elderly.!

Also, don't rule out similar types of services - elderly or assisted living, housing for deaf or blind, some sort of physical rehabilitation, etc. 

or perhaps someone who was elderly, a vet or who was disabled? 

@Devin Elder there are also some free CRM (I believe that is Customer Relations Managment) tools available.

The tenants are elderly and I have a feeling they were unable or unaware of what had happened and the issue was not addressed in a timely manner.

Regarding a particular type of sale, which is again coming into common use, of an elderly owner's home, whereby the property is sold at a figure lower than the normal market value and the owner retains the use and enjoyment of the property during his lifetime, the estate agent must be well aware of all the necessary elements.Property Marketing SystemsThis information is currently being compiled by the ICREA-member association in this country.

One thing I didn't mention, is that my mother committed suicide (by gunshot) there in 2009...When my father's dementia started getting more serious, early this year, I hired an elderly-care manager to handle a variety of tasks like getting him to doctors (he wouldn't go with me), and eventually transition him into assisted living, where he is now.I was initially thinking of selling the house to pay for his care, so I discussed it with her.

@Jon Holdman, I emailed the agent, with a list of the issues, and why the property wasn't worth the $250k per lot, so that he might be able to use it to get his seller to understand reality, as the sellers daughter (an attorney) wants her elderly dad to sell the property so he can move closer to her, therefore; maybe he will relent and take less.

I am sure you can find a tenant who is looking for an in-law suite for an elderly relative or younger teenager.
