If you are in a hot climate they also shade the roof and provide savings to AC costs.  

It's much colder, darker, and dryer.

See the crime map of New Braunfels attached (Darker is more crime). 

You got it made in the shade if your goal is $6k cashflow and you have all the resoruces to build. 

Find out if your Section-8 and your locality will let you glass block the basement windows vs the bars.I like grey (cement floor) paint on the floor, a little darker grey on the wall (4 blocks up), and ceiling white on the top blocks to make a horizontal feel to the whole basement.And to paint any columns or sewer stacks wall grey, and put a light over the machines.Whatever noise the dryer makes is probably cutting down it's service live--so a fix there might mean money in your pocket in the long run.Hard nosed inspector--(could be worse), what else can you do other than comply and hope the next inspection is as good as gold.Good Luck!

And it shows the darker side of the risk involved with using lines of credit to invest in deals. 

Moss is a great option if shaded.

We apparently need a new shade tree in the front yard (no idea why);5.

We didn't replace the back windows, as those are 100% in the shade and don't affect thermal load (they probably do insulation, a bit, but  not enough to justify the cost from our end).We had just replaced glass panes, as needed, but after one tenant's boyfriend thru a hammer thru one (three panes down), the another's son managed to break four panes at once (he must have thrown something thru both windows or fell in them arm-first and with thru both at once), the replacement glass costs were adding up -- that last one would have cost more than replacing both windows in the unit.

IT cannot be any shade of owner occupied or cha ching.
