As far as someone who is not had much experience turning a unit, there are things, simple things such as paint sheen, and paint color that can be a positive or a negative for the rental.

The logic behind using yellow as a background color on postcards it to match the post office's notice color.

We can be fat, skinny, short, tall, multitude of skin colors and nationalities, and have all kinds of things against us and yet still succeed.

are you changing them up each time or are you sending the same one over and over (ie. look, different color paper, different wording, etc.)3. 

Exterior color combination sucks.

Paint colors, cosmetic repairs.7. 

My advice for you (and my future self) so far is:- be very detailed about underwriting your deal- add at least 30% to what you think your rehab will cost (even if this figure came from a GC)- have a really detailed design concept before work starts (including fixtures/trim/color scheme/etc)- check with your city/township's building department and see what permits you need up front- have more than one exit strategy- add a few weeks/months to your projected timeline- purchase cash if at all possible- build relationships, take notes, and learn lessons along the way- have funGood luck! 

I mean what else are they saying for that $7k, "break-through" revelations of genius like pick 1,2,3 wall colors for your units and paint em all with that keeping the paint codes so refresh paint can be done via touchup.....

Am I changing the color ink pen I using?

Just from a personal standpoint, my 77 year old mother received a colored small envelope (like it was a birthday card or something like it from a friend) with a handwritten printed font, that was pretty good with just a quick glance.
