I know interest rates are higher on these cards and my credit score would take a hit (as opposed to using my existing card) but does anyone have any experience doing this?

This would be the first time question to post - and reader of many posts, I'm a student of RE for the past nearly (2) yrs.The strategy is to wholesale a property and target to net $5-10k to a buy & hold investor.  

@Brianna SchmidtMy plan is to attend although I will not have any true networking supplies with me (Although I do use Vista Print, a lot, I have to design a new card for REI and put that order in next week).

Here is Massachusetts I use websites such as patriotproperties.com and visionappraisals.com that usually give me the assessor card information.

Don't pull this card until you have already got them down on price as far as possible.

Steve you must put a deposit by credit card before you can bid. and if you are the high bidder even though it may state that the bid did mot meet the price they will want you to wire EM money to closing agent within 2 hours

Although you can't help installment loans (house & car) affecting your credit score, you can have a great effect on your revolving credit (credit cards/storecards) by keeping your debt-to-credit ratio at 30% or less.

A couple of years ago, prior to Amendment 64, we rented one of our houses to two professionals who had their medical cards. 

I've never used them for postcards, but I just used them for Business Cards and they did a great job and were the lowest price I could find.Also, if you have a great color printer you could always buy cardstock from OfficeMax and print your own.

Not much time for questions but I got enough in to blow his scheme, I left and waited in the parking lot and handed out my business cards.
