I just got an estimate for 6 exterior doors to be replaced and painted to match existing colors for $6000 or $1000 a door.If you are out of the area and he’s not charging by the day or hour I think your solid!

Maybe if you shared the ad-dress we could suggest a suit-able remedy. 

I don't care about the color of skin, the kind of accent they have, and what their sexual orientation is.

If you are open to doing a color stain let them know that.  

I'm currently using a spreadsheet with color coding to indicate the following:Red - remove from list/returned mailYellow - responded to adBlue - letters sent, no responseWhite - no letters sentWhen calls come in, we have a lead sheet we fill out.

If the walls did not have to be painted, but updating the color scheme might be considered necessary to get your property rented with the shortest period of vacancy.

I use the same colors in all houses (many do this), but whats different for me is that I do this even in working class neighborhoods.

My suggestion is to also stick to factory pre-mixed colors (never ever custom mix) and always write down in your lease the color that you put up so that your tenants can do touch ups and not have to ask you what the colors are.

You could alleged that "protected clases" of people are more likely to be renters and that the HOA's "no rental" policy "has a discriminatory effect where it actually or predictably results in a disparate impact on a group of persons or creates, increases, reinforces, or perpetuates segregated housing patterns because of race, color, religion, sex, handicap, familial status, or national origin."
