Yellow letter for Withdrawn House

[Jim Robinson]

Hi everyone! This is actually my first post on bigger pockets, however I've been reading forums for a year or so... So I'm looking into buying my first house in the coming months in the suburban Philadelphia area. A property I have been watching (waiting for the sales price to drop) was just withdrawn from the market. So I was thinking about writing a yellow letter to the owner and seeing if they are interested in selling the property without a realtor... Essentially I am trying to eliminate the realtors commission so the buyer can save some money and I can get a better deal. I was just wondering what I should watch out for? Do I have to wait for contracts to expire with the realtor? Is there a specific way I should word the letter? Really appreciate any insight! Thanks so much! Jim R
