When I told him they would have to paint them back to the original color, he said the Landlord approved it.

Plumbing by-passes or abandoned lines; collapsing sewer lines; badly corroded supply and waste lines (both can be from inside or outside corrosion) fixtures with very hard to find components; hidden electrical junction boxes...or non-existent boxes at junctions; outdated and/or underrated distribution panels; knob and tube wiring improperly connected to, or extended with, romex; Switches wired incorrectly, breaking the neutral instead of the hot side; no, or poor grounds for improper outlets; overheated connections, outlets, switches, and light fixtures; improper wire sizes for circuits and overloaded circuits; and plenty of others...all very costly to troubleshoot, locate, and correct individually.

I'm reaching out to see if anyone can recommend any general contractors that have experience/expertise in light rehabs for converting units into Airbnb properties.

Cosmetic upgrades including new appliances, vanities, lighting, flooring.

Property is a triplex, on the river, 150 of water frontage, lots of light maybe thinking renting long term one, and airbnb the others. 

.- Paint (ceiling, semi-gloss for trim, color(s)) - 2 coats?

No, their eyes dart between the clock and the road, long practice assuring them that if they make it to the second light on Maple by 8:22 they still have a change to pull into their job's parking lot by 8:39 and punch in before their 8:45 flex-time deadline passes.

I think we could probably get $500+ with a light rehab.

When they don;'t really trust you or have a reason to make sure you are credible.Now look at this:Every colored dot is where traffic clicked on the site. 

I had a fancy colored map but I can't find it.
