hmmm, tricky.
I'd say do your 90 day report AND apply for your year extension with the TM30 that's on file now (using the copy you have) Elite is holding your hand so it'll go right thru.
Then have the new owner file a TM30 for your new address after the 1st
AND
then you use the new address to file the next 90 day report.
That's the way to pull it off with the least problems
