In Baltimore you can buy a house for under $10,000 and rent for $300-700, that's good cash flow, you may not want to invest in that area.Cash flow in my opinion is a function or your negotiating skills, your ability to use power prospecting methods and to create leads that make sense.

Also it is common to collect an additional security deposit as well.FYI... the tenants union is very active and powerful in Seattle, so become familiar with their website and the messages they promote to tenants.

And if you have CH/AC all that usage of power( heat/air per sq ft) makes your HVAC system operate longer, putting a toil on YOUR UNIT, thus complaints...."

Depending on the state you are in, and/or the type of verbiage you use in your lease, you have the power to assist your tenants in breaking their lease early. 

At this point I learned the power of leverage.

Stop reading books and going to classes, oh and stop building your " power team" Heres  a crazy idea, find a deal, do not worry about selling/ flipping it, the money will find you,,,,,,,,,,, Good luck 

Company A is an engineering firm with multiple full-time W2 employees.

Currently, the property gets its power from solar and windmill.  

I have a unit where they placed the forced air furnace and duct work for the 2nd floor in the attic, and pulled the power and gas supply through the chimney.
