Assuming there has been no activity on the account, it should come off your credit report 7 years and 180 days after it first went late. You are probably right that the account keeps getting resold. Those sometimes sell for pennies on the dollar, and the collectors may come after people who are no longer legally required to pay. You can read more here: Does Your Old Debt Have an Expiration Date?
FICO® Scores are developed by Fair Isaac Corporation. The FICO® Score provided by ConsumerInfo.com, Inc., also referred to as Experian Consumer Services ("ECS"), in Experian CreditWorksSM, Credit TrackerSM and/or your free Experian membership (as applicable) is based on FICO® Score 8, unless otherwise noted. Many but not all lenders use FICO® Score 8. In addition to the FICO® Score 8, ECS may offer and provide other base or industry-specific FICO® Scores (such as FICO® Auto Scores and FICO® Bankcard Scores). The other FICO® Scores made available are calculated from versions of the base and industry-specific FICO® Score models. There are many different credit scoring models that can give a different assessment of your credit rating and relative risk (risk of default) for the same credit report. Your lender or insurer may use a different FICO® Score than FICO® Score 8 or such other base or industry-specific FICO® Score, or another type of credit score altogether. Just remember that your credit rating is often the same even if the number is not. For some consumers, however, the credit rating of FICO® Score 8 (or other FICO® Score) could vary from the score used by your lender. The statements that "90% of top lenders use FICO® Scores" and "FICO® Scores are used in 90% of credit decisions" are based on a third-party study of all versions of FICO® Scores sold to lenders, including but not limited to scores based on FICO® Score 8. Base FICO® Scores (including the FICO® Score 8) range from 300 to 850. Industry-specific FICO® Scores range from 250-900. Higher scores represent a greater likelihood that you'll pay back your debts so you are viewed as being a lower credit risk to lenders. A lower FICO® Score indicates to lenders that you may be a higher credit risk. There are three different major credit reporting agencies — the Experian credit bureau, TransUnion® and Equifax® — that maintain a record of your credit history known as your credit report. Your FICO® Score is based on the information in your credit report at the time it is requested. Your credit report information can vary from agency to agency because some lenders report your credit history to only one or two of the agencies. So your FICO® Score can vary if the information they have on file for you is different. Since the information in your report can change over time, your FICO® Score may also change.
A credit report is a detailed report of an individual's credit history prepared by a credit bureau. Credit bureaus collect information and create credit reports based on that information, and lenders use the reports along with other details to determine loan applicants' credit worthiness. In the United States, there are three major credit reporting bureaus: Equifax, Experian and TransUnion. Each of these reporting companies collects information about consumers' personal details and their bill-paying habits to create a unique credit report; although most of the information is similar, there are often small differences between the three reports.
