You repaint the entire unit for $3k.

We have spoken with several realtors and they all wanted us to repaint the walls before listing.I can fix the door guide (only $5), replaced the Roman Shades with mini-blinds ($8 each because if I ma installing new Roman Shade it would be a lot more), I patched the ceiling myself ($1), mowed the lawn by avoiding those few spots with new sods without any issue (even after it rained), cleaned all of the windows, and bought paint ($13) and repaint the sills ourselves.My question is, shall I deduct from the security deposit for having to repaint the walls?

That's probably the strategy I will eventually employ for the 1500sf or so of popcorn over my head as I type this,  but it would be hired out along with a complete interior repaint,  and its owner occupied.   

Probably new kitchen, bath, flooring, repainting, repairs to plumbing/electrical...if not outright having to replace those systems. 

I repainted the entire house, fixed one toilet, resurfaced and finished the deck, landscaped, and cleaned.

During this time, neither you nor any agent repainted or inspected the property at the end of each lease period, and wear and tear is expected.

Then put money into the house - took out a wall, new floors (fake wood looking tile), had a bunch of old oak trees taken out, removed hundreds of bags of leaves, repainted the inside and so on.

$15k from the state was put back into the property immediately - took a wall out, new floors, repainted the whole thing.

it needs to be re-painted, and the bathroom needs tile.
