A real estate portfolio can generate passive income and long-term wealth. However, it’s not something you build overnight. Before investing, it's important to learn more about real estate portfolios, including how to build one, their pros and cons, and other relevant details.

What is a real estate portfolio?

A real estate portfolio is a collection of real estate investment assets. A typical portfolio may include rental properties, flipped homes, and real estate investment trusts (REITs).

Real estate investors curate their portfolios to meet their financial objectives, whether that's maximizing cash flow, achieving long-term appreciation, or securing tax benefits.

Of course, geography and the types of assets in a market can have a significant impact on what you can add to your real estate portfolio.

There also is a difference between managing a portfolio and owning one. Portfolio managers take on more work for the potential of greater rewards, while passive investors opt for a hands-off approach by outsourcing day-to-day operations to a property manager.

Types of real estate portfolios

Here are the most common types of real estate portfolios:            

  • Residential portfolios. These consist of single-family and multifamily properties.
  • Commercial portfolios. Includes office buildings, retail outlets, and hotels.
  • Industrial portfolios. Includes factories and warehouses.

How to build a real estate portfolio

Now that you know what a real estate portfolio consists of, you can start to build one.

Outline your objectives and goals

First, set investment goals.1 For example, do you want to own a certain number of rental units within a year? Are you targeting a specific benchmark for return on your investment? Defining clear goals lets you curate a matching portfolio.

Remember to consider your risk tolerance. A high return target can be appealing, but it may also require you to take a greater risk and implement more effective risk management. Only take on a level of risk you are comfortable with.

Choose a starting point

Buying your first investment property can be intimidating, but there are low-barrier ways to break into the market.

For example, you can house hack your primary residence. This means renting out part of your home, whether it’s a spare bedroom, a basement apartment, or an accessory dwelling unit (ADU). You also can buy a home with more than one unit, live in one unit, and rent out the rest.

Alternatively, you could buy shares in a REIT for relatively little money. This provides you with exposure to the real estate market without requiring hands-on work.

Whatever you do, start out small so you can learn the ropes before moving on to bigger and more complex property investments.
