Might as well remove the remaining wall and make it-up with some small glass paneling.  

We do not know the prior condition of the property before the current tenants moved in, but there were broken panes of glass on the windows, piles of hidden trash on the side of the house, etc when they moved out.

@Wade WilliamsHi I realize this is an old post but hope to tall to you about it anyway.

Bugs like tall grass.

So many other things that I have paid for her - window glass replaced, cleaned out of the backyard which are not my responsibility.  

Staring out the looking glass wandering if there is greener grass somewhere in the world; Quick and to the point, SFH sucks, get into simple assets that have economy of scale, like townhouses, apartment complexes, and commercial.

I told her she had to fix the glass since she broke it.

This place WILL stand tall, I guarantee it.

Unfortunately, I'm the only 6' tall boy from Indiana who can't sink a basket!

Then everything you've done would be copacetic and you won't have to worry about paying back taxes on recaptured depreciation that wasn't taken.But that may be a tall order for a cpa or attorney to pull off given your mom is paying rent.
