Rent or buy a home in 2026? Why a mathematical winner may be a real-life loser

 

Agathum advertisement

 

“February 2026. You have 40,000 euros in your account. And the pension fund reform allows you to withdraw money from the second pillar. 10 billion euros, which were frozen for decades, are now available. Are you one of thousands of Lithuanians who are facing the same question today: what to do with this money?

 

Your parents say: “Buy an apartment! Now is a good time.” Your friends say: “You should invest in shares!” Your partner asks: “Will we rent for a few more years, or is it worth buying?”

 

We did the math with real Vilnius numbers: a disciplined renter mathematically earns 212,300 euros, a homeowner – 91,200 euros. The difference is almost 121,000 euros – the renter accumulates more than 2 times the wealth!

 

But research shows that homeowners are significantly richer than renters.

 

How is this possible? Mathematics shows one thing, human psychology shows another.

Salience bias: why everyone is wrong about the real income from housing

 

Imagine a scenario: you buy an apartment for 200,000 euros. After 25 years, you sell it for 533,000 euros. “I earned 333,000 euros!” you exclaim to your friends over dinner.

 

But this is not true.

 

You only see two big numbers: bought for 200 k, sold for 533 k. But you forgot: interest to the bank, constant repairs that are getting more expensive every year, maybe the real estate tax, and, most importantly, the lost return on that initial deposit that you could have invested in an alternative investment. So your real return is much lower than it seems.

 

This psychological trap is called the salience bias - our tendency to focus on emotionally vivid information. A large number sticks in memory. But we ignore less noticeable things: ongoing monthly expenses, the influence of inflation, alternative investments, the impact of crises, our own behavior.

What does science say?

 

Long-term studies confirm a fundamental difference between asset classes.

 

Real Estate

 

Research by Nobel Prize winner Robert Shiller (1890–2020) and an analysis of 16 countries’ real estate (1870–2015) by economists Óscar Jordà, Katharina Knoll and colleagues paints a clear picture: the historical real return on housing is about 1% above inflation (or about 4% nominally before inflation). Good asset preservation, but not impressive wealth creation.

 

Stocks

 

The S&P 500 and MSCI World indices over the same period (1926–2025), including all crises – the Great Depression, 2008, COVID – show a real return above inflation of about 7% (or about 10% nominally before inflation).

 

The difference is 6 percentage points per year. Doesn’t sound like much? Look at what happens in the long run:

 

in 10 years – double the return,

in 25 years – quadruple the return,

100,000 euros with a 1% real return (4% nominal) becomes 128,000 euros in real value.

 

The same 100,000 euros with a 7% real return (10% nominal) becomes 543,000 euros in real value.

 

This is not a small difference. It is the difference between “I can retire early” and “I will have to work until 70”.

 

But if the mathematics is so clear, why are owners often several times richer than renters?

 

Let's look at specific typical numbers with the example of Vilnius, then we will explain why reality is different from mathematics.

Vilnius 2026: real numbers

 

Purchase: what does the owner's expenses look like

 

50 sq. m new apartment in an average district of Vilnius – Žirmūnai, Pašilaičiai, Justiniškės – today costs about 200,000 euros. This is the average market price of a new apartment in such places; not in the center (where the square meter is 5,000–6,000+ EUR), but not on the outskirts (where it is 2,500–3,500 EUR).

 

The initial costs are higher than many people think.

 

Initial contribution: 50,000 EUR (25% – we calculate the typical average that people choose, although the minimum would be at least 15%; in fact, as many as a third of people buy housing with their own funds, but we did not estimate this).

 

Transaction costs: 1,500 EUR (notary ~1,000 EUR, registration ~100 EUR, valuation ~200 EUR).

 

Furniture and appliances: 10,000 EUR (refrigerator, washing machine, dishwasher, sofa, bed, table, chairs, wardrobe, curtains, lamps - this is realistically all you need, because in Lithuania apartments are usually rented with furniture and appliances).

 

Total initial costs: 61,500 EUR.

 

Mortgage: 150,000 EUR with 4.5% fixed interest for 25 years = 835 EUR per month. This payment is FIXED for 25 years. 835 EUR in the first month. 835 EUR in the 300th month. Over 25 years, you will pay the bank 250,500 EUR - of which 100,500 EUR is interest (real costs), and 150,000 EUR is the principal amount (this is your property, which returned to you through the principal payment of the loan - the apartment became your full property, without a mortgage).

 

Other monthly expenses (increased with 3% annual inflation):

 

utilities: 80 EUR (heating, water, garbage),

management and maintenance: 90 EUR (mandatory, cannot be waived),

repairs: 50 EUR (on average for a new apartment - minor repairs, painting, plumbing details, electrical repairs; although a new apartment requires minimal repairs for the first 5-10 years, later these costs are very real and growing),

insurance: 30 EUR (mandatory with a mortgage),

household appliances: 17 EUR (average monthly fund for replacing large household appliances - refrigerator, washing machine, dishwasher are replaced every 10-15 years),

renovations: 30 EUR (kitchen/bathroom renovation after 15 years).

 

Total: 297 EUR in the first year → 399 EUR (in 10 years) → 621 EUR (in 25 years)

 

Critical moment: in the first year your total monthly housing costs are 1,132 € (835 € mortgage + 297 € other costs). With an annual inflation rate of 3%, after 25 years, other expenses increase to €621 per month, and the total monthly expenses reach €1,456 (€835 fixed mortgage + €621 other expenses). The mortgage payment remains nominally unchanged throughout the period, and the growing part of the total expenses over time is no longer the bank, but the operation of the property itself.

 

Over 25 years, you will spend:

 

initial expenses: €61,500,

mortgage (fixed): €250,500,

other expenses (growing with 3% inflation): €129,800.

 

Total: €441,800

 

After 25 years, assuming that housing prices in Vilnius will grow by an average of 4% per year (based on data from Robert Shiller and other economists mentioned), your €200,000 apartment will be worth €533,000. Mortgage fully paid off. Apartment 100% yours.

 

Net return: +91,200 EUR, or 21% ROI.

 

Not bad (remember that the apartment itself is on your consumption expenses line!), but not impressive.

 

Rent + investment

 

You rent the same 50 sq. m. new apartment with furniture and appliances in the same location for 850 EUR per month (rent excluding utilities). This is the average market price for such an apartment in Vilnius in 2026. To this is added 80 EUR in utilities (heating, water, garbage), which the tenant pays separately.

 

Total monthly expenses in the first year: 930 EUR (850 rent + 80 utilities).

 

Since the rent increases by 4% per year and the utilities by 3% per year (both growth rates correspond to the nature of these expenses), the total monthly expenses of the tenant change as follows:

 

Year 1: 930 EUR,

 

Year 5: 1,084 EUR,

 

Year 10: 1,314 EUR,

 

Year 20: 1,931 EUR,

 

Year 25: 2,341 EUR per month — almost 2.5 times more than at the beginning.

 

Total money spent on rent (including utilities) over 25 years: 459,780 EUR.

But here comes the interesting part — investing!

 

The critical moment: the initial payment. This is where the real difference happens. You have the same 61,500 EUR that the owner had to spend at the beginning (including furniture and appliances, since you are renting a fully furnished and equipped apartment). This is not “extra” money. This is your very important financial decision: should you use it to buy real estate, or invest in an alternative if you choose to rent?

 

Then, if you invest in a very broadly diversified stock portfolio, buying, say, the Vanguard FTSE All-World UCITS ETF (USD) Accumulating ETF with >3,600 positions - with an expected 10% nominal average return per year, including all crises, EUR 61,500 becomes EUR 666,602 after 25 years. This will be 91% of the total final value of your stock portfolio. That one decision with that EUR 61,500 determines almost everything.

An additional advantage: monthly contributions

 

In the first year, the tenant pays EUR 930, the owner's costs are EUR 1,132 - so a difference of EUR 202 per month. You can also invest this difference.

 

But the owner’s mortgage is fixed (835 EUR), and the rent and utilities are rising faster. After about 7-8 years, the tenant is already paying more than the owner. After that, the difference only increases in favor of the owner.

 

This means that you can only invest additionally for the first ~7-8 years. If you invest the full difference (202 EUR in the first year → decreasing to ~0 EUR in the seventh-eighth), this money grows with compound interest and becomes about 67,000 EUR after 25 years.

 

Nice, but that’s only 9% of your portfolio. The real game was won or lost with that initial 61,500 EUR.

 

The final result

 

666,602 EUR from the initial deposit (91%),

 

67,000 EUR from the monthly payments (9%).

 

The value of your entire portfolio: 733,602 EUR.

 

Total cost: 521,280 EUR (61,500 initial + 459,780 rent with utilities).

 

Return: +212,300 EUR, or ~41% ROI.

 

The renter’s return is more than twice that of the owner.

 

But here’s the thing: it’s all about that initial decision of 61,500 EUR. Monthly payments are also important, but not critical. If you invest your initial payment in a disciplined manner – you win. If not – you lose, regardless of what you do with the monthly differences.

Comparison: who wins on paper?

 

The renter wins an additional ~121,100 EUR. This is not a small difference – perhaps more travel, a better car and an earlier retirement.

 

But it’s important to understand the nuances here. The renter can only invest the extra money for the first ~7–8 years. After that, he pays more than the owner and has nothing left to invest. The first 7-8 years are critical – if   the renter doesn’t use this window in a disciplined manner, the advantage disappears.

 

The math is certainly on the renter’s side, but here’s where the psychology comes in—why are homeowners so much richer in reality?

How Psychology Wins: The Behavioral Gap

 

A 2017 Harvard University study, “A Revision of the American Dream,” sought to answer this paradox. The researchers analyzed the behavior of thousands of households over decades, trying to understand: if the math is on the renter’s side, why are homeowners actually richer in reality? Their conclusion was this: the difference is not due to higher home value growth, but to individual choices—how much renters actually save and how they behave during crises.

 

In other words, homeowners aren’t richer because they bought homes. Homeowners are richer because their mortgages forced them to save and protected them from their own mistakes. Home is not a better investment. Home is a better proxy for your own behavior.

 

Again, it all starts with one critical moment: what happens to that 61,500 EUR?

 

Disciplined investors – maybe only ~10% of people

 

You have 61,500 EUR. You invest in a very broadly diversified portfolio of stocks – for example, the Vanguard FTSE All-World UCITS ETF (USD) Accumulating we mentioned earlier.

 

Crises are coming. In 2008, the market fell -53%. In 2020, COVID -34% per month. There will definitely be other crises over the next 25 years. We don’t know when, we don’t know what kind, but they will.

 

Your reaction: You know the story. Since 1870, the market has always recovered. You don’t check your investment account too often, and during major drops, you might not even open your broker’s app. When everyone else is selling, you stick to your plan, or maybe even buy more!

 

After 25 years: 61,500 EUR becomes 666,602 EUR.

 

Result: 733,602 EUR portfolio.

 

Typical person: about ~90% of people

 

You have 61,500 EUR. But maybe you don’t invest all of it. Maybe you spend some of it on other things. Maybe you just keep some cash “in case you need it.”

 

Discipline problem. Will most people miss a mortgage payment? Virtually never. But delay a transfer to a brokerage account? There will always be a reason. “I need it for a car this month.” “Summer starts next month.” Investing becomes “when I can” rather than “I have to.”

 

Behaviour during crises. When the market drops -53%, you can sell stocks in 2 seconds, with one click. And most people sell stocks at the bottom. In 2013, the market had already risen +150%, but your money was gone. And during every crisis, history repeats itself.

 

The result: a portfolio much smaller than planned. Many do not save anything at all.

 

A typical person with a mortgage

 

You have 61,500 EUR. You spend it all: 50,000 down payment, 1,500 transaction, 10,000 furniture. The money is locked up in the apartment.

 

When the market is falling, stocks can be sold quickly, but an apartment? Within 3-6 months, and during a crisis it can take even longer. Transaction costs are a few percent. Where would you live? The bank still wants 835 EUR — you can’t postpone monthly payments.

 

So you just pay 835 EUR every month, as always. You don’t think much about the value of the apartment, and after a few years it recovers.

 

The result: a 533,000 EUR apartment, practically guaranteed.

 

Conclusion: a disciplined investor will have 733,602 euros (but discipline and cool nerves are required), the portfolio of a typical tenant will be much smaller (because they panicked during the crisis, or maybe they didn’t invest at all), the typical owner will have 533,000 euros (the mortgage forced them to save).

 

And the lack of liquidity of real estate, which most people call a “disadvantage”, may actually have been its greatest advantage.

Another important point that numbers do not measure

 

This is protection against forced eviction from rented housing. Perhaps the strongest argument for buying: ownership protects against housing price increases if you want to live in a particular place for a long time (due to work, family, schools). Unexpectedly sharply rising housing prices are a big risk for a tenant.

 

Realistic scenario: In Vilnius, rental prices in Žirmūnai increased by 60% in 2015–2025. What should a tenant do who has not saved up the initial deposit on time? Either they pay a lot more, or they move to a more distant area, or they are pushed out altogether if their salary is not enough. And the owner? His mortgage is fixed – rising prices are not affected, he already owns the house.

 

Another aspect: certain types of houses – houses in a more remote or forested area, houses with large areas or in more specific locations – are simply not available for rent. If you want something more unique, you usually have to buy.

What will you choose?

 

The math is clear: the disciplined investor wins. But in the real world, owners are much richer, although residential real estate is usually not superior to stocks as an investment. Perhaps Lithuanians love real estate for a reason. In our culture, “our own corner” has a deep meaning. And perhaps most importantly, housing protects us from our own impulsive decisions.

 

If you are a disciplined investor:

 

you have been investing regularly for several years,

you have an automated system,

the crisis of 2018 did not bother you,

you can look at -30% without much emotion,

peer pressure does not work?

 

Then rent - mathematics is on your side.

 

But if at least one "no" on that list - then buy. A mortgage will protect you from yourself. After 7-8 years, your friends who are tenants will pay more than you.

 

Not sure which type to attribute yourself to? Then it is probably better to buy. Because if you doubt - 90% chance that you are a typical person and a mortgage is created for you.

Gediminas Misevičius’s comment

“I have been investing for 20+ years, and it was really interesting to read, and since I like mathematics, I decided to check these calculations with Excel based on the same assumptions. Although most of the numbers are completely correct, I found significant shortcomings:

 

1. Unestimated GPM aspect - in the case of NT sale, there is no GPM, and for withdrawn investments, GPM would have to be paid at the end of the term when withdrawing earnings. Thanks to the investment account, the money could serve as passive income without withdrawing more than invested.

 

2. In your calculations, you correctly assessed that the landlord can invest the difference for the first 7 years, thus earning additional income, but you did not assess that the owner (who took out a mortgage loan) can invest the difference from the 8th year onwards, thus increasing the return (even a total of 97.4kEUR over 8-25 years with an analogous 10% annual return). This is necessary to assess, because money has a different price in different periods, and one should calculate with the SAME expenses each year for both the renter and the owner with a loan. Therefore, the real income of the owner, who would spend identical money every month, would not be 91.2k, but in the amount of 188.6kEUR. This is very close to 212k for the investor (without the influence of GPM).

 

3. Alternatively, maintaining the same annual cash costs, it is possible to do it differently - the investor, starting from 8 years, when rent + taxes begin to exceed the owner's costs, takes the shortfall from the investments, thus reducing his portfolio by the appropriate amount (so that different cash flows would not affect him). In this case, the investor would grow his portfolio to 590.6kEUR (no longer 733.6kEUR) and after excluding the costs, only 69.3kEUR would remain (against the owner's 91.2k) - without the influence of GPM.

 

All calculations were made using assumptions - a small change is enough to tip the scales in one direction or the other. Since I am also a proponent of diversification, the conclusion would be this - it is better to take out a mortgage loan, and later, when the loan burden decreases, to invest, which is what I did myself.
