@Cassandra Sifford I would recommend self leveling compound ( mix and pour) for uneven concrete floors and even over existing tile.It gives you a smooth flat surface to work with and is relatively easy to mix and spread.

Market slides downward, you lose ALOT more money in value and cash flow is still negative.Yes you may have made a mistake in keeping it expecting to make money instead of selling it after you moved out, but don't make more mistakes going forward and potentially compound the problem. 

leaving the funds as is 49k to 85k in 9 years is about 6.5% annual compounded return, or 87% total return. 

It was only recently, when listening to the audio book "The Compound Effect" did I truly grasp how much I required immediate gratification. 

The inspection revealed that the property needed a new roof and the basement walls had bowed in due to runoff from the neighbors driveway.

This ended up actually moving the house and bowing the center cross beam in the basement.

Like any long term investment, our time and effort compounds with age.

Don't let that be a worst case scenario sales pitch, its not meant to be, but its more like an understanding that though you may have rentals that for 20 years have no major problems (for example a new roof), meaning you feel like your cashflow is blowing away any Cap X formulas, with every passing year you are at a statistically increased (compounded) likely-hood that in the ever nearer future you will have to spend 10s of thousands wiping out your cashflow on a new roof (or whatever major problem).  

Tape is embedded in a setting compound at all joints and intersections.  

Your vulnerability to vacancies is greatly reduced, your cash return is far better, your compounding income is increased exponentially.
