Cases on your record may affect your ability to rent an apartment. Some apartment complexes may deny your application if they see an arrest on your record although your criminal case was dismissed and you have no convictions on your record. The fact that they can see what you were charged with, gives most people cause for concern thereby denying your application. You are innocent until proven guilty, but some places judge you for being arrested.
Other instances people run into problems include background checks during job applications, and loan applications for buying a home. Someone applying for a job as an Uber driver was rejected for the position based on the dismissed traffic cases found on their record during the interview process. It is important to expunge your record as soon as you get the chance because the expungement process is not immediate it takes some months be finalized.
