I have paid off old collections and 2 judgements. Will my credit score go up at least 20 points ?

Answer 1

No they will not raise your credit score directly until years later. The trick is to try these 10 steps, which will raise your credit score within a year!

I raised mine to well over 700 points from 500 using these steps:

# Know and Track Your Credit Score
# Never Miss a Payment, Starting Today
# Never use more than 20% of your Available Credit
# Keep Credit Cards that Have No Annual Fees Open For as Long as Possible
# Extend Your Credit Limit on Cards You Already Have before You Get New Ones
# Get Credit Cards that Have CashBack Rewards to Contribute to your Balance
# Transfer Your Balance to a Credit Card with a Lower Interest Rate and a Higher Available Credit-
# If You Think You Are Going to be FORCED to Pay a Bill Late Ask for an Extension or Payment Plan
# Take out a Small Personal Loan and Repay it Over a Year
# Ask Someone With Good Credit if They will Account Shadow you
