Or literally blood relatives?

It would appear that the kind of people that CAN get a mortgage are looking for something higher-end, and the people that could AFFORD the mortgage on these lower-end homes do not have the credit or wherewithal to ever be able to own a home.None of the homes are "upside-down", per-say, but something is only WORTH as much as someone is willing to PAY... and so far, all indications are that no one is willing to pay anything.The area has a combination of an aging and low-educated, low-income population with very little "new blood" being attracted. 

You either have landlording in your blood or you don't.  

@Trevor Aydelott Elk City is heavily reliant on the oil industry for its economic life blood, and tends to boom and bust along with it.

I Like this thread a lot to (funny) I made Bandit signs saying HIGH BLOOD PRESSURE?

Blood, Sweat, and Tears.

Accept this guy at your own peril because I don’t care if he donates blood at the Red Cross helps little old ladies cross the street and volunteers at the local soup kitchen the guy is surely going to give you problems !!

Too rich for my blood.

I’ve done very well on rough streets, but that money is hard earned and comes with a lot of blood, sweat and tears.

Keeps the blood pressure down and you get a "look what I made" sense of accomplishment.
