I get a margin loan for a mutual fund investment and pay $9,000 interest. I earn $10,000 dividend.
To the extent the $10,000 in dividends are strictly considered ordinary dividends (not qualified) then you can use the margin interest to offset the $9,000.
You simply cannot offset investment interest with qualified dividends.
