350 yellow letters or 700 postcards?

[Chris G.]

Hello all.  First I want to say a big thank you to everyone for their willingness to freely help newbies such as myself. 

I just finished my second rehab on a buy and hold property and will hopefully have it rented out this week sometime.   I would like to do some direct marketing for my next purchase so that I have more room, price wise, to have some help with the rehab (I did all the work myself on the previous properties to keep costs down).   I'm working with a small budget of about $350 a month for marketing so my question is,  would it be better to mail every month to 350 absentee owners with yellow letters or 700 with postcards?  I remember reading on a yellow letter thread that it was said yellow letters will definitely get the phones ringing but you may get more motivated sellers off the fewer calls you recieve from postcards.   Does anyone have any stats comparing actual close rates of the two?  Thanks again everyone.
