My understanding is I can't have a blood family member manage. 

There is a big difference between unrelated renters and those related by marriage and blood, but that's a different story.2.

Because going after him for monetary damages seems futile to me given what his financial situation looks like, which is consistently job hopping and not having any money to pay rent, so essentially I'd be trying to get blood from a turnip or however that saying goes.

I don't want to spend the time on it, or get my blood pressure up, so I just gave it to petscreening.com.

I literally put blood, sweat and tears into that first property.

A lot of blood sweat and tears went into the bus.

All tenant has to do is if they see the light blinking they just have to shake it outside into their trash can and the rat will fall into the trash with no blood or nasty liquids.

Blood, sweat, and tears.

So our blood, sweat, and tears have been poured into these 2 units for my whole lifetime.

Blood, sweat, tears, or money, you have to pay for your lessons, and that's the only currencies they accept.
