How do You Buy Preferred Stocks?

You buy Preferreds just like you would any stock.  Put in an order in your brokerage account and wait.  The prime difference with preferred stocks is most trade very ‘thin’ (little volume) so you should always use ‘limit’ orders or you may pay way more than is necessary for your shares.
