I’m curious why you’re disputing the 30 day lates? If they’re real and the lates don’t disappear then you’ll likely still have the lates plus your dispute on your report. Its unlikely you’ll get approved for another mortgage with any disputes on your report. Also, a dispute removes the acct from some score considerations so it could have a positive or negative impact on your scores.

Derogs from 2009 and 2010 now gone after 7 years. I started paying attention to credit scores in about 2014. It's taken a few years but credit scores are now good after starting in the high 500s back in 2011
