Secondly, yellow letters seem to be the go-to letters for the best return rate.

I have heard that most people swear by yellow letters.

I'm looking into the yellow letter mailing advertising has anyone used this type of advertising?

Write it how you feel it should.If that were the case I wouldn't write a yellow letter at all.

This is not as fast as the yellow letter companies out there, but the letters are more real and the cost is much less, especially for a start-up.  

@Claire @Claire Trammell I would also draw doodles on the front of the letter if you are mailing yellow letter mailers will be more likely to open your letter

Jumbo loans are picky about income and credit you must be financially strong.You can always write an offer on yellow notepad paper and not be represented by an agent.

Aloha,Assuming you have your ducks all in a row, with signed move in condition form that details "new paint" on walls and ceilings; photos of same; copy of signed Rental Agreement with the prohibition in it; photos of move out condition, showing disgusting yellow nicotine stains running down the walls, and "clean" areas where pictures had been hanging; and your actual invoices for having the cleaning and painting done by appropriate, legitimate, professionals, then YES, charge them.

Beyond that, your best bet is to send a yellow letter or doorknock.
