If it were me I would work on the ones that were going to be on your reports longest. One of the bureaus will consider EE (early exclusions) starting at 6 months from the delete date and since you are closing in on that I would go that route with those. I believe another of the bureaus is 3 months and the final one would do one month early. I can never remember which is which so hopefully someone else would chime in and provide that info. As for the possibility of deletion and finding contact info the search feature is a great tool to use so you can check out others experiences with the same company. Google will also provide the corporate address in most cases or you can use the address on your credit reports. Sometimes you can even find corporate email address on the Internet. I don't know anything about mortgages so hopefully someone with more knowledge on that score can help. There are also templates of Goodwill letters in the helpful rebuilding thread. Just be sure to use that as a template and tailor it to your situation since you don't want it to sound like a form letter. As for how often you should send them I would say every 30 days. If you can find an email address you might want to also consider sending one via snail mail as well just to cover your bases.
