Having a duplex can have its disadvantages. Before deciding to buy one, you should be able to know that you are sharing the commodities of your living space with someone else particularly a tenant. Before allowing a tenant to live in your duplex, you must be able to inform him or her about the rules and regulations that are being implemented in your unit. You should be aware of how they will be using the living area in order not to have any setbacks when they start living there. As a landlord, you should also look after the safety of your tenant and be able to provide the basic commodities such as a comfortable living area.
