Is It Better to Pay Rent or Buy Real Estate? Applying Buffett’s Wisdom in a Calculated Analysis

Last Updated on 10 February, 2024 by Abrahamtolle

Real estate is one of the most significant investments you will ever make in your lifetime, and deciding whether to rent or buy can be a complex and emotional decision. On one hand, buying a property can provide a sense of security and financial stability, while on the other hand, renting allows for more flexibility and freedom. In this article, we look at the economic aspect of renting or buying real estate.

From an economic perspective, it makes more sense to buy stocks than real estate (not considering leverage).

Charlie and I don’t know our cost of capital. It’s taught in business schools, but we’re skeptical. We just look to do the most intelligent thing we can with the capital that we have. We measure everything against our alternatives. I’ve never seen a cost of capital calculation that made sense to me. Have you Charlie?

– Warren Buffett

Is renting more rational than buying your residence (economically)? We seldom hear about the opportunity cost of homeownership. In April 2021, the Dividend Growth Investor had an interesting thread on the subject:

Is It Better To Pay Rent Or Buy?

What is the opportunity cost?

The definition of opportunity cost is defined like this by Investopedia:

Opportunity costs represent the potential benefits an individual, investor, or business misses out on when choosing one alternative over another. The idea of opportunity costs is a major concept in economics…..Because by definition they are unseen, opportunity costs can be easily overlooked if one is not careful. Understanding the potential missed opportunities foregone by choosing one investment over another allows for better decision-making.

An investor should always try to increase the opportunity cost. In economic terms, it means the difference between the best use of your capital and the second, third, fourth, etc. The famous investor Charlie Munger regards Berkshire and Costco as his opportunity cost, obviously only when the price is right.

This makes sense: why would you invest your capital in your tenth best idea?

Let’s calculate Warren Buffet’s opportunity cost:

Let’s assume Warren Buffett could have invested his capital (31 000 paid for the house) at 20% for 63 years. Compounded, without considering taxes, this is 3.02 billion today.

Not bad.

We have no idea what the house is worth today, but a lot less, perhaps 500 000 USD. Considering Buffett has paid maintenance, real estate taxes, etc every year, the “investment” in his property is worth even much less. If the value is 500 000 today, the CAGR is a modest 4.5%. However, with leverage, the calculations would be different, of course. Most borrow money to buy a house, while hardly anyone borrows to buy stocks.

However, most investors wouldn’t be close to a 10% return. The long-term passive CAGR has been around 10% over this period.

Warren Buffett is, of course, unique and is a 100% rational investor. However, not everything can be valued or be put down to an exercise in compounding:

Realistically, real estate is a good investment for most people

Real estate is a good investment for most people because it’s a long-term investment: most people own real estate for most of their lives. Would they do the same if they owned shares? Most likely not. They would be more prone to behavioural mistakes.

In an earlier article we discussed the pros and cons of real estate and stocks:

Realistically, the opportunity cost is not the return in the stock market. Most people don’t invest in stocks at all. We can argue they should, but in reality, they don’t.

A home is more an emotional decision – not financial. It feels better to live in a home you own than renting – for most people. You can do what you want, and you feel safe in paying down a mortgage than paying to a landlord.

Buying and selling real estate is complicated and expensive

In Norway, you pay the broker at least 1% per transaction, depending on the object’s value. A lot needs to be added: photography, decoration, insurance, etc. The real cost is at least 2%, probably more. You can buy an index fund for free.

We can safely assume maintaining a property costs 1% a year. An index fund costs from 0.1 to 0.3% annually.

And not to mention the legal mess with real estate. Leaks, fire, plumbing, etc. The list is long. You are unlikely to have any legal disputes in the stock market.


Homeownership is overrated – economically speaking.


– Is buying or renting real estate a better economic decision?

The economic decision between buying and renting real estate involves factors like security, financial stability, flexibility, and freedom. It’s a complex decision with emotional considerations.

– Why does Warren Buffett question the concept of the cost of capital in real estate?

Warren Buffett and Charlie Munger express skepticism about knowing their cost of capital. They focus on making intelligent decisions with available capital, measuring everything against alternatives. The concept of cost of capital is seen as potentially flawed.

– What is opportunity cost in real estate, and why is it important?

Opportunity cost in real estate represents the potential benefits missed when choosing homeownership over other investment alternatives. Understanding the opportunity cost helps in making better economic decisions.
