DOORS:--> Front Door - I can't tell by the photo if the door is broken or if the window in it needs to be replaced and the door rehung and repainted.

Many of your tenancies will be 10-22 months... you don't want to have to repaint and install new carpet every year or two.

Restoration was $18,000 - scrub all walls, air purifiers, etc); replacement of damaged items (kitchen damage, replace carpet, repaint entire unit, other clean up was another $18,000.  

I got a better finish out of the new, of course, but I'd say, if I were in your shoes, why not just prime, texture, and repaint the walls to your liking?  

For example, is it really necessary to clean the ducts, sweep the chimney, add insulation, repaint the house numbers on the curb, etc.?

If you'd like to purchase a slightly rusted, repainted, brown awning, I'd gladly post an add over in the marketplace where we can discuss making a fair deal on it.  ;-)I think I'll be able to pop one of the panes out for replacement.  

The house was gross, barely repainted, with 70’s carpet.

Right now, I'm seriously considering going through and repainting the entire place a platinum white. 

New carpet/flooring, repaint everything including the kitchen and bathroom cabinets, remove any wallpaper and replace drapes worked on my house that had heavy cigarette odor and yellowing.

A handyman might be great for fixing a leaky faucet, but when it comes to turning a unit, you need to coordinate multiple teams to repaint, clean, carpet, etc.
