Duplex houses are residential structures that are built with two or more separate units. Typically, the lower floor contains a living room, while the upper portion is usually home to a kitchen. Investing in a duplex can be a lucrative and rewarding venture.

However, it requires some research and a careful assessment of your needs. You'll need to make sure you have enough cash in the bank to cover a down payment. Also, consider the resell value of your property.
