Hello. A collection is rated as an R-9. This rating lowers your credit score by a minimum of 50 points, therefore you can expect the opposite to occur when a collection is deleted. You can get a snap shot of your credit score(s) for free by visiting creditkarma.com (this will give you your Trans Union score) and Privacyscore.com (it is believed that this may be your Experian score). Best of luck. Christina of Everlasting Credit Repair.
