Maybe attend some local REIA groups, pass out business cards, etc.?

Building a budget always reminds me how hard the student loans hit me and how terrible I was with credit cards.

You have to get a Lowe's and Home Depot Credit Card. 

Also get a credit card that has travel points and charge everything to it so that you can use them towards visiting property if you have to.  

Should I attract leads with yellow cards and wait for a call, or go and look for abandoned properties and try to find the owner of the property.

OK  If you dont have 700+ credit and can not get some unsecured loans/cards to flip at a much smaller unsecured rate/payment then use hard money, if the alternative is to sit at your day job wishing you were not there. 

This is AFTER putting $44,000 of medical bills on my credit cards.

(i had to gave them my credit card with application)who should i call?

You may want to bring business cards. 

Adding combined years of experience in the DFW market and saying "Not ready to sell, keep this card", all has helped.I'm a firm believer in that most of it has to do with luck and timing.
