Are Duplexes a Good Investment?

Some home buyers purchase multi family homes because of the investment potential. A duplex can be a good investment but the purpose of using FHA financing is to buy a duplex to occupy the property as your primary residence while having the benefit of some rental income to offset your monthly mortgage payment.

The best duplexes from an investment standpoint are ones where the rental income will fully cover your mortgage payment which includes principal, interest, taxes and insurance. If you have found a property where the potential rent is high enough to cover the debt service, then it is likely a very good investment.

Buying a Duplex as a First Home

One of the benefits of buying a duplex as a first home is the ability to claim the property as a primary residence. Doing so opens up the opportunity to use FHA financing with a small down payment and competitive interest rates.

You will also have the other tenant subsidizing your mortgage payment which can be a huge benefit for first time home buyers. One day, you can then purchase another home while continuing to hold onto the duplex as an investment.

When you own a duplex, you are now a landlord which means you need to respond to the various complaints from the tenant. Usually it will be related to things that need to be repaired. Learning how to collect rent and dealing with tenants who do not pay can be a challenge owning a duplex.

First, you can get a gift from a relative for the down payment.

Next, you can also find down payment assistance.

Finally, you also have the option to look into seller financing.
