As far as getting more from them--as they say "you can't squeeze blood from a turnip."

Getting into 6-7 loans in your first year is like blood-doping for months and hiding a rubber bladder of dog urine under a merkin for the drug test at the end of the stage.

Heck, even the bathtub could be used to wash off blood evidence. it doesn't mean we should exclude any of these things in the rental unit. 

Also get you should get your blood tested for carbon monoxide. if it's forced hot air and you smell gas in the whole house it could be flue gas in vents. 

Symptoms of this problem can include:changes in the pH balance of your bloodlow blood pressureserious injury to the eyes, including blurry vision, burning, irritation, and in extreme cases vision lossskin damage, resulting from tissue injury with burns and irritation, said CDC https://www.cdc.gov/niosh/npg/npgd0115.htmlLong-term complications may occur after breathing in high concentrations of chlorine.

However, I'll admit I'm avoiding reading up on the topic in order to keep my blood pressure somewhat near the levels of the living

First off, we had a higher rate of new wars during the Obama administration.Second, when there is blood on the streets there is money in the banks.

I know that you have to do this with the rent and I can see the reasons why but I can also see how it could cause a lot of time, conversations and bad blood between PM and tenant.

Most of these deadbeats have done this before and the prior landlords just threw up their hand and said: " you can't get blood out of a turnip".  

Personally, I wouldn't; too much expense/risk for my blood.
