Are there new accounts showing? Usually by 1 year you would have recovered. More time might be needed if AAoA took a big hit.
From six to twelve months. As stated earlier, it depends on your current profile, apps, inquiries, etc. I apped for two auto loans and one cc in a seven month period last year. Account one is now one year old and I haven't recovered all of my points yet but expect to by the time the second account hits the one year mark. As always, YMMV.
