I would suggest that you buy from the MLS. Depending on how large of a purchase you are looking to make you can buy in bulk but depending on the area you wont find as many options for buying in bulk. If you wanted to buy in Florida or Michigan it would be easy to buy bulk property but where we are in Southern California, it's not as common. I think the MLS is your best option. Auctions are not great because so many people show up that often the home is bid up so high that it's above other comparable property on the MLS. Most of the property that ends up in the auction are property that didn't sell on the MLS. I would stick to the MLS and be patient!
