Making mailings is one way to find good deals, but the return on a mailing is very low and expensive.Doing a mailing campaign is a passive way to market for deals - If you want to accelerate your potential to make money in this business, I would suggest using active marketing ---Farming - looking for vacant, ugly houses - tracking down the sellers - make an offerSit in your local rent and housing court - no body wants to be there - great place to find burned out landlords who will be glad to discount their property to youExpired listing - these are sellers who have a property that did not sell - you can make their dream of selling a realality and profit at the same timeRather than licking stamps, designing silly yellow letters or post cards, stuffing envelops, buying postage, running to the post office or sitting home waiting for the phone to ring -- you'd be lot more successful by entering your market and doing peo-active marketing for the gold nuggets you are seeking.
