I've read (all my knowledge is theoretical) that tenants on government assistance can be really rough on properties (I also see that as painting with a broad brush) but the government assistance side of that is pretty stable income, and it doesn't seem terribly difficult to raise rent either, just requires 60-days notice instead of 30. 

I am in Baltimore and lead paint lawsuits are a big issue.

Ducting is the 1/2 the size of a rain gutter and you can paint the ducts to match the current exterior.

Will be paint full, but at this point, I’m ready to walk away.

So I have no experience with painting exteriors.  

We even created a 'sight unseen' addendum to be included with every lease so tenants know that unless they asked for contingencies [ie: repaint entire home] the home is as-is, so they should not expect a freshly painted property unless they asked for it prior to signing the lease.

Depends on how extensive the remodel work is, a cosmetic flip paint, trim, cabinets, vanities don't trigger permits here in WA state. 

This may include examples such as maintaining the landscape, a minor plumbing repair, doing shingle repair on a leaky roof or painting a few rooms between tenants.

We decided to focus on time home buyers, which is typically a young couple with kids looking for; a good school district, a backyard, 3bed room two bath, home, two car garage, a basement, an updated kitchen and bathroom, all painted an interesting neutral color scheme.

Home search to reno planning to paint to plumbing to floors to record-keeping and contract writing, self-managing (all).
