When you think about real estate investing, the first thing that probably comes to mind is your home. Of course, real estate investors have lots of other options when it comes to choosing investments, and they’re not all physical properties.

Real estate has become a popular investment vehicle over the last 50 years or so. Here’s a look at some of the leading options for individual investors, along with the reasons to invest.

Rental Properties

If you invest in rental properties, you become a landlord—so you need to consider if you’ll be comfortable in that role. As the landlord, you’ll be responsible for things like paying the mortgage, property taxes, and insurance, maintaining the property, finding tenants, and dealing with any problems.

Unless you hire a property manager to handle the details, being a landlord is a hands-on investment. Depending on your situation, taking care of the property and the tenants can be a 24/7 job—and one that’s not always pleasant. If you choose your properties and tenants carefully, however, you can lower the risk of having major problems.

One way landlords make money is by collecting rent. How much rent you can charge depends on where the rental is located. Still, it can be difficult to determine the best rent because if you charge too much you’ll chase tenants away, and if you charge too little you’ll leave money on the table. A common strategy is to charge enough rent to cover expenses until the mortgage has been paid, at which time the majority of the rent becomes profit.

The other primary way that landlords make money is through appreciation. If your property appreciates in value, you may be able to sell it at a profit (when the time comes) or borrow against the equity to make your next investment. While real estate does tend to appreciate, there are no guarantees.
