Based on your past management experiences I would call it a wash and move on to your next tenant.If you want to succeed you will need to hone your landlord skills. 

This all shows exceptional actions by Landlord of clarity and legality, washing free of any liability, leaving full liability squarely upon tenant. 

When the tenant vacated, the pavers looked like they are now 20 years old, there are stains and it was power washed, but those stains/discoloration are still there.

If I pay off my note, the added income of not having a mortgage offsets the loss of income from selling the rental so it is a wash and I have peace of mind because I'll have 3 out of 14 of my properties paid off. 

I want to sell one of my Washington, DC. properties to have a larger down payment for a new primary residence in Irvine, CA.The property is a condo in Northeast Washing DC (Brentwood neighborhood near the Red line Rhode Island metro station (0.07 miles) that has been on the market for 135 days and isn’t selling.

Sometimes they didn't wash them very well.

Then you will spend money on coffees, taking people to lunch, parking, gas, car washes, once you do make a sale you will spend some cash on a nice closing gift. 

- Do their cash flow projections indicate that they will remain solvent or require additional capital injection at some point prior to profitability?

Now I'm obviously salivating to find another and wash-rinse-repeat my way to financial independence!

Ride the wave, and it's about to crest, if you wait for every last dollar you are gonna be washed out with the tide instead of being ready to ride the next one.
