Needs complete exterior painting and has some deferred maintenance issues.  

Fix soft spots in floors (3/4" osb)  Windows - caulk and plexie glass, Roof - rubber, if exterior is trashed new siding on ferring strips, and white paint interior, carpet (no pad just glue).Make sure 3 things work perfectly: electrical (may need to update), plumbing (pex lines with heat tape wrapped in pipe insulation, and furnace (don't slack on this).These tenants want to move and thins to work. 

If a PM has to call a licensed contractor for every drippy faucet and paint repair the landlord will be hurting in no time.Have had terrible experiences and significant financial losses due to  PM misdeeds.

Carpet, paint, vinyl flooring, etc. 

If I sand the old walls, when I paint the whole room, will the old walls look different from the new drywall walls?  

@Bill G. you first post was so helpful it made me completely ignore your second post and take any "advice" you have and completely disregard it, while basically telling me i am ignorant idiot without any direction in what way i should go to accomplish this opportunity you have managed to not only waste my time but paint yourself as a buffoon.

Now that we've closed, fixed the house up a bit (basic paint, windows, a few other cosmetics), and have it rented out for positive cash-flow, I'm looking to bring on board a property management company so that I don't have a situation of my dad getting called up in the middle of the night if there is an issue with the toilet, power, etc.If this works out, I'm hopeful to continue learning and also acquiring more properties for my buy and hold approach.  

Has anyone ever rehabbed or marketed their properties with low Voc paints, sustainably harvested wood or bamboo, cork or refurbished wood. energy saving appliances, air filters, fruit trees, water gardens, passive house.I'm thinking this is something I would like to do but of course it's all about economics and these green things usually cost more.

I pay less for very good quality paint at SW and Klingers than the mediocre stuff at box stores based on my volume buying discount. 

In CA, when you disturb, you dispose the right way, that window may be costly, EPA certified painter and disposal will be costly, any kind of painting for that matter, the house is 1920, you need lead tests. as for asbestos, same thing.
