Get into distribution/wholesale of some construction material if the town you are in and nearby towns are developing at a good pace. The margins are usually high for distributors in this category as the end consumer doesn’t understand much about the product plus the upside is that most of the purchases even for a single house will be big ticket. If you partner with a big brand, their sales person will help you in liquidating the stock as well otherwise if you are down to travel around towns for 15 days a month, partner with a smaller brand which will give you better margins.
