50k for paying off collections? or Down payment on a Flip?

[Antonio Sosa]

Hey guys im a newbie, and saving money to get into real estate flipping. I have a low 600's score and completing my second year of work history to qualify for a loan, i wanted to ask this comunity for some guidance. should i pay 1k to fix my credit with a credit repair company who may help me settle and pay off debt from my earlier 20's or save that cash and learn how to make more money and find a way to start flipping homes once my 2 years of work history are complete. Loan officers tell me that its vital for me to have a solid 2 years of continues work history for a loan. Should i be focusing on creative financing and not even worry about credit?
