Inspectors in my area are now being trained to say "weird substance, could be mold, needs to be examined professionally" on every house.    

Also, many people are prescribed controlled substances for AanxIrty, PTSD, pain management, etc.

Some of the beams have this sawdust looking substance on them. 

Let's see; I want to be a real estate investor, so I'll put my money in a property that is dirt cheap, low rent, high vacancy (excluding squatters and substance aficionados), high crime war zone and believe I'll be successful?  

It is substance over form.  

I'm also highly appreciative that I found a place which aligns with my views for providing substance, actionable info - sans hype.Real Estate ExperienceFinally bit the bullet last year when I purchased my first home.

my father has been  a landlord for 20 years in detroit so i get to hear all about them since ive been around1 self employed people they  always fail to pay on time and leave dirt everywhere to be cleaned 2 those who turn into a life of crime and decide the unit is either a great place to distribute narcotics meth and other dangerous substances or worse they decide its a perfect place to produce drugs having the fbi lock down the unit and investigate my father this has happened 5 times now3 have had two units completely scrapped and i mean interiors gutted, copper pipes ripped heaters boilers even the shower and toilets stolen, these skin heads even tore threw the walls to steal all the electrical and hvac, needless to say they costed tens of thousands 4 one tenant decided it was a cool idea to pay for one month, then strip the entire location. once the tenant was evicted the house was burned to the ground. no charges were ever given .5 worst of all is when people die. once a drunk driver in a pickup truck drove right into the living room and killed not only himself but the tenants watching tv in the room, weve also had about 3 that i remember who we found laying dead from alcohol poisoning, the last one we payed to be sent and burried near his family  also we once had a witch doctor, this old lady disappeared after renting for a year. when we went inside the walls were covered in blood, there were rotting animals that had been cut open, candles and wax stuck all over the place. 

If you have ever opened one up, the bacteria are the black tar like substance on the walls of the tank and are the bottom of the 3 liquid layers in the tank.

Also, since their services can be very time limited, there is always the issue of the tenant finding suitable employment, keeping said employment, the employer not jerking the tenant around (especially with low income workers, it goes both ways), etc. not to mention whatever other issues, be they family, substance use disorders, disabilities, etc. that could have contributed to them being in need of a high level of services.

This is a great "cash like substance" to use when applying the refinancing method I use.
