The fact that all your belongings are still in the home and you will not re-paint and carpet after each guest leaves also attributes to the more granular stipulations. 

Easier to touch up/match with the passage of time.My guess is that grey will fade or darken with time resulting in having to repaint entire rooms as opposed to touch up between tenants.

In rentals, you are likely repainting every year to three years no matter what, and charging tenants for any painting after 2-3 years is not allowed, at least in the states where I rent, so cost is a factor.  

So I paint the hardwood floors, let the dogs go nuts, then just repaint it when I have a switchover.

This is our real estate investment firms first renovation from start to finish.Some of the highlights:- Converted deteriorated 3-season porch into covered deck- All new interior doors (closet doors were used where traditional doors should of been used)- New front door, front and rear storm doors- Repainted kitchen cabinets, new hardware, re-finished countertops (thanks rustoleum)- New Trafficmaster vinyl tile floor in kitchen- Refinished dishwasher with appliance paint- New Fridge and Range- Painted the whole house (Glidden Duo)- Cleaned up hardwood floors- New tile in bathroom and kitchen- Repainted and put new hardware on vanity (bathroom)- New hardware/locksets on all doors- Drylocked basement walls and unfinished it (water damage)- New carpet coming for basement (not pictured)- New electrical box, outlets, switches, light fixtures- New roof (house and porch)Too many pictures to post on here.

Or, let's say there's a drywall repair or a cabinet that needs repainting, they may be under the impression it should be an easy one-visit fix. 

Perhaps popcorn texture is common/popular in your area, but in many areas, it's actually considered out-of-date and undesirable, and you may be adding some value by getting rid of it and repainting the ceiling.Just a thought...like I said, I don't know your area, so I could be way off base...

another picturethere is a crack in the center tile which is why I think I might as well take all the tiles off and maybe repaint the bathroom.

This does Not count the repainting that was necessary.

Wipe down with bleach to make sure, kiltz then re-paint.
