Margin lines of credit against stocks?

[George Leeman]

I am currently waiting on a eventual stock market crash while taking loans against properties while they are at a high, but my plan is to invest a large amount of cash into stocks when the market is down. Does anyone here use margin loans or lines of credit to finance properties? If so, can anyone recommend their institution?

I am mostly interested in using lines of credit to make down payments on buy and hold multiple family units.
