Four days later we received a letter stating we had not painted the house in the approved color scheme.

I do split test my postcards.My perspective on the yellow letters is: (1) they are not branded, and I'm building a brand in my local market; (2) I don't want to use a "mind game", for lack of a better term, to make someone call - where I have no reason besides some highly general list to believe they wish to sell; (3) everything - all marketing - ties into my global online marketing - so sending out materials in the real world that does not in detail reflect my website, colors, branding, company name doesn't jive with my business model (even my white letter, comes with my brand business card and House Heroes customized letterhead).

They don't always have the color you want - I spent weeks looking for a stainless dishwasher - but for an inexpensive solution at reasonable prices, they really can't be beat, plus you're helping a non-profit charity as well.I find Sears Outlet to be overpriced and Home Depot/Lowes is right out, unless they are having a super, mega, ultra holiday weekend sale.

Within the city of Austin, monthly housing inventory rose 0.2 months year-over-year to 2.1 months of inventory.

They use colorful envelopes which make it stand out from the standard yellow ones. 

Also, if scratched or chipped porcelain is the same color all the way through.

Love your exterior color changes - especially your choice of accent/trim color!  

For example we have a triplex that was quarts at $2200, then rose to $2700 when they obliged the correct age of the home.

As far as the extra paint it sounds like you just picked the color for the next flip and saved yourself some labor (waiting around at Home Depot ) costs.

My opinion, eliminate and let them choose the color and price of the refrigerator they want.
