I don't want to sugar coat it.  

Unfortunately, you can't get blood out of a stone.

How about your stress level when a tenant is getting emotional, how do you quantify stress or higher blood pressure?

this is just a first impression, after all my personal goal is not to be a blood sucking landlord, but like few people have mentioned, this is a business. 

Most of what I've looked at is in the southwest suburbs: Sugar Land, Missouri City, Mission Bend, Katy areas.

I don't want to sugar coat it, but you need to know this.

Usually next of kin(ship) or blood relative.So, I would be dealing with the Personal Representative (executor and/or administrator).Think of probate as the person that has not done proper estate planning. 

She was 18 years old at the time, being exposed to 10x the legal limit dealing with a mom complaining about her keeping the windows open at night... even if an inspection only catches 1 out of 1,000 and even if it's not you're own blood, in this line of work you do have to value a life.

Sugar ants, they need to put out ant traps.

@Joe WhiteBy Philadelphia zoning you can have a group of people living together and using housekeeping facilities in common, “but not to include more than three persons unrelated by blood, marriage or adoption"So by the city ordinance you should not rent to more that 3 unrelated people aka 3 rooms.
