It's not a big secret and I've even read it in ebooks but this does work and can make you decent money if you have the time. Storage units are everywhere (at least in the US) and they are big cash cows for the owners so new ones are popping up everywhere all the time. You pay them $50 per month (more or less depending on your area and size of your unit) and they give you a space where you can store all the shit you don't want or can't fit in your house. There are a million reasons why people use these storage units. Some people run businesses out of them and keep their supplies in them, some are downsizing or upgrading their home and put all the excess stuff or stuff they plan on bringing home sooner or later, some want more space at home and move stuff they don't use regularly in their, some businesses have little store or warehouse space and also put items they are overstocked on in them, some people put items they want in a climate controlled environment (some storage facilities offer climate controlled units), etc... I'm just trying to give you an idea of reasons why people use storage units so you can see the potential of what I'm going to explain. If you're late on paying your monthly rental fee for your storage unit, the company adds a late fee. The late fees are high compared to what you're paying. A lot of times when people fall behind and the total keeps accumulating they just can't/won't pay the debt. After a few months of non-payment the storage companies sell the units at a public auction. If you look in your local newspaper classifieds/announcements section you're very likely to see announcements for Storage Auctions. Due to the fact that they are basically repo'ing the units they have to give public notice which is why they place ads in the newspapers. When you find an auction close to you, you visit and they have bidding on unopened storage units (at least that's the way it works in my state). This is there way of getting their space back and making a few bucks to pay for the months of unpaid space. Now what you want to do is buy these units. This is like playing the lottery but with a much higher chance of getting your money back and a very high chance of making much more than your initial investment. The first thing is if it's a smaller unit have a max budget of say $50, go up to $100 for larger units. Quality of contents, pricing varies depending on where you live or where you go, so I'm just throwing out numbers that have worked for me in the past. Make sure to budget yourself. Also try to go to some of these auctions before you're an actual buyer. So if they have an auction this Saturday go, don't buy anything and just see what the customs are in your area, what's an average selling price for each sized unit, look and see what's inside of some units (even if it's from a distance). Then next month or whenever the next one happens you're ready to buy. Don't go over your budget because if you buy a shitty unit you'll be even more pissed. I know a guy that is an antique dealer and he uses this technique to make a large amount of cash offline. He doesn't even use any online marketing techniques to get rid of the shit he collects he sells everything in antique stores (on consignment), flea markets, and auctions. I do not do this often because of the amount of time it takes. Be prepared to spend several hours hauling shit around figuring out what's worth anything and what's not. If you have a pickup truck this is the time to bring it with you. Each place has different policies on how long you can take to get rid of the contents. I prefer to take everything immediately or later on the same day. I don't own a pickup truck so I had a friend let me borrow his every time I needed it. If I couldn't get the pickup truck and there was really good stuff inside I'd rent a cargo van or moving truck from UHaul. Here are some contents that I've gotten from these and seen others get: Computers Laptops Big Screen TVs New Furniture Antiques Old Baseball Cards Motorcycles (I don't know the legality of actually being able to keep these) Paintings Tools Electronics Gold and Silver Jewelry And tons of other good stuff. Here are some not so great contents that I've gotten from these and seen others get: Empty Units Bales of Hay Old Furniture Broken Electronics Dirty Pentium 1 Computers Bags of Kitty Litter Fake Jewelry And tons of other straight to the dumpster items. It's a risk you take on every unit you buy but the pay off can be big. Imagine you spend $50 on a unit and you find a 1955 Mickey Mantle baseball card worth thousands or a antique vase which you immediately sell for $2000. Also what I do is maintain my own storage unit right around the corner from me to keep the shit I don't want at home, that has value, stored. I've also used Ebay, Craigslist and similar sites to sell the stuff. Furniture for example first I try to sell it on Craigslist (and similar free ad sites), if know one wants to pay, I just post that it's free and people come to get it so I don't have to worry about disposing of it. Where I live I don't have any problems with disposal of stuff that no one wants (even furniture) so also keep in mind you'll probably be throwing away tons of shit. Smaller stuff that has value goes on Ebay with no reserve. If you like a low risk gamble go to a storage auction, bid on and win as many units as you can afford and start separating the good from the bad. Just remember this can be very time consuming so plan to spend at least a whole day purchasing, sorting, throwing out, and advertising your items. This is also a low cost way to start an Ebay business (and own the actual merchandise and not have to rely on suppliers and drop shippers). You can cookie stuff everyone that buys your limited edition GI Joe with Kung Fu Grip.
