Removed paneling, removed carpet, refinished hardwood floors, tiled the kitchen, new countertops, new lighting fixtures, and new paint.

My latest rental property had the main lines from the meter to the panel box wired in aluminum, and the rest in copper.

That came up at during a panel discussion at our REIA a while back.

I suppose I'd also need the solar panel. 

There are also great hardwood lookalike laminate floor panels that are super durable and give an above average look.You don’t need to be the best finish in town as there are certainly diminishing returns, but being better than average is a major advantage.

But I'll add a sub panel for some lights and plugs at least.  

Roof, HVAC, plumbing, Elec service and panel, etc.I prefer if a few other things have been done that will ensure happier tenants.  

You have electric of only $100, but if the house has one of those Federal Pacific panels, you're looking at a new panel already.

Perhaps there's more deductions somewhere like opening a Roth, buying an EV, purchasing Tesla solar panels before the end of the year so I can put it on this years tax deduction but I don't think that will work since I don't think they charge you until installation but I'll have to look into it.

Only if you haven't kept your settlement agreement handy.One last tip from our panel of legal research experts who shall remain nameless...Even if you don't get clear language waiving your deficiency many times the settlement agreement shows that you owe $0 or a note in the amount of $0.With this documentation you have at least some evidence to support the argument that in your negotiations you bargained for a waiver of deficiency and were explicitly told by the lender during negotiations or perhaps at close that this was the meaning of the $0 or the note in the amount of $0.Good luck
