It ironically was built in 1937 as well.Something to keep in mind going forward; it is our understanding that many homes built prior to 1939 used sandstone foundations and obviously older "cloth type / knob and tube" style wiring.1940+ homes builders started utilizing cinder block foundations and bx wiring, which is as mentioned a ground wiring system.All the best

We put it in our properties, and water damage happens very easily with bubbling and it looks terrible quickly.

I plan to give a refund of security deposit (less any damages) however I am unsure if I need to refund any portion of the actual rent or not?

Anywhere within a 30 to 40 mile radius of downtown Chicago if the financials make sense & the specific block has no to low crime.  

What about butcher block counter tops from Ikea? 

Of course that would get my attention, as my license would be suspended until I repaid the bonding company,  then issued the county a new bond, which may be very difficult & expensive to get any company to write.The State of Arizona actually charges every contractor a fee of about $500/year, and runs their own fund that allows any customer to collect up to $30,000 for damages.  

I have been driving by parks that easily are twice that price and alot of them are in pretty dicey areas, i.e. no jobs, drugs, cars on blocks etc etc.

Owning guns is a pain in the butt in CA, so I'm relatively light on the guns but have various bladed instruments staged about our home (that I own, obviously).The hoarding is the only thing you described that strikes me as unusual.This dude probably wants to do what is expected of him, which is not causing permanent damage to the property and pay his rent on time, in exchange for basically being left alone to quiet enjoyment of the unit.

We have already put on a new roof ($9,900), new fence + block windows ($2,400), new windows ($3,900), and new back stairs/porch ($2,700).  

Luckily I got him to pay the last  So I did my final inspection on the unit and deducted the damages and returned the remaining deposit.
