Is there any further opportunities for income, e.g. laundry or additional storage?

In total rent should be $2075 currently and about $75-$100 a month in laundry income. 

In the end we had to tear off the front porch and dig down 9 feet to wash the foundation, 3 coats of elastomeric sealant along with a waterproof membrane over the whole thing.

The last stretch is level.The problem is that the topsoil keeps washing away, leaving exposed rocks, ranging from golf ball to softball size. 

Or limited to, rents, parking fees, forfeited deposits, laundry income and fees.’So, to me this reads like a % of the operational income, but utilities aren’t an operational income, are they?

You accepted condition of building / unit when you took over..Wear and tear on carpet this age is ridiculous,, it's has no appreciable life left.You could charge him if he broke a window since your ownership, or that type of damage,, but anything nicotine damaged from your point of ownership is pointless in trying to recover any damages from this tenant.Any why you would have DEEP CLEANED a carpet that was in this type of unit was a waste of your money.You will not get rid of the smoke smell until you wall wash with TSP all walls, woodwork, windows, then prime coat walls with KILZ,, clean all filters, any vents spray inside after washing out as best possible with spray kilz,, don't try to save any window treatments. 

When they started using a lot of hot water (shower, laundry etc) the Carbon Monoxide detector went off.

He was tired of having a rental and the house had a small laundry room fire.

At the same time I learned and ran my commercial/residential pressure washing company as well.
