I’m a recent college graduate and I am trying to help my mother but her first home. She wants to open an Adult family home in the Seattle Metro area. We have been having trouble finding trustworthy Real Estate agents ...

I don't know.On a case study there was an elderly couple with their first SF deal that took 3 months to rehab and no renters at the time of the presentation.

In addition in some states the actual property tax may contain discounts for the elderly or homesteading (owner occupied) status. 

You may also consider consulting with an elder care planning specialist.

Also people that are obese, and the elderly.

Since its your home, elderly on a fixed income may be your best candidate.

However, it makes sense if they are more for student housing, disabled, elderly, or homeless, financially challenged people who would have difficulty paying the deposits to turn on utilities. 

I've sold options to elderly couples and I've sold homes at $80k+ over market value to new investors.

Hello All,I have a friend in the Madison, WI area who is in the process of moving her parents into elderly care facilities.

It's a pretty close-knit street with elderly folks who walk around the neighborhood a lot so don't want to be "that house".
