Yeah generally the contractor will go over different types of shingles with you and aside from color and appearance the biggest difference is the years 20 year, 25 year, 30 year etc...I have never personally gotten a roof replaced through insurance so I don't know if the insurance dictates what "quality" of shingle they will pay for. 

colors?

If you use 1 paint color for all your apartments then touching up or fixing holes becomes very easy.

Renovations that made the home move-in ready and pass the homeowner's home inspection with flying colors.

There are different colors on the map, but no legend.

No miscommunication and potential legal issues with the new residents telling you that was broke before and you said you would paint this a certain color or you said you would fix this or that.

There are subtle unique items and market specific knowledge that they likely are unaware of because this is not their market.According to Rentometer, the average 3 BR SFH in Los Angeles rent rose 13% last year. 

If you find yourself in LA/Pasadena, let me know and we'll go to the Rose Bowl and fly a bit.

I don't put my rose-colored goggles on when doing projections.

Over the course of a week or so we worked with the contractor to choose the floor layout for the basement, choose finishes and colors, and order all materials.
