Real Estate vs. 401(k): Which Builds More Wealth Over 30 Years?

The 401(k) has been America's default retirement plan since the 1980s. Contribute, get a match, invest in index funds, and hope you have enough in 30 years. It's simple, automatic, and widely available.

Rental real estate takes more effort. You find deals, manage properties, handle tenants, and deal with toilets. It's messy, hands-on, and intimidating.

So which one actually builds more wealth?

Let's run the numbers side by side — with realistic assumptions, real tax implications, and no cherry-picking. Then you can decide for yourself.

The Ground Rules

To make this a fair comparison, we'll use these assumptions:

• Time horizon: 30 years
• Starting investment: $40,000 (equivalent to a down payment or lump-sum 401(k) contribution)
• Annual additional investment: $12,000/year ($1,000/month)
• Starting age: 30, retiring at 60

We'll track total wealth generated including all income streams, tax benefits, and compounding effects.

The 401(k) Path

How It Works

You contribute pre-tax dollars (reducing your taxable income today), your employer matches a portion, and your money grows tax-deferred in mutual funds or index funds. You pay income tax when you withdraw in retirement.

The Numbers

Assumptions:

• Annual contribution: $12,000 (under the 2026 limit of $23,500 for under-50)
• Employer match: 50% up to 6% of salary ($3,000/year on a $100,000 salary)
• Total annual investment: $15,000
• Average annual return: 8% (S&P 500 historical average after inflation adjustments vary, but nominal returns average ~10%; we'll use 8% to account for fees and realistic fund selection)
• Expense ratio: 0.5% (bringing net return to ~7.5%)

Year-by-year growth:

At year 30: ~$1,381,000

The Tax Hit

Here's what people forget: you haven't paid taxes on any of this yet. When you withdraw in retirement, every dollar is taxed as ordinary income.

At a 22% effective tax rate in retirement:

• Pre-tax value: $1,381,000
• After-tax value: ~$1,077,000
• Sustainable withdrawal (4% rule): $43,080/year or $3,590/month

That's the reality. Your $1.38 million is really about $1.08 million in spending power. And $3,590/month in retirement income — while helpful — isn't luxurious.

401(k) Strengths

• Simplicity. Set it and forget it.
• Employer match. Free money (the match is a guaranteed 100% return on that portion).
• Tax deferral. Compounds without annual tax drag.
• No management. Index funds run themselves.
• Bankruptcy protection. 401(k) assets are shielded from creditors.

401(k) Weaknesses

• No control. You're at the mercy of market performance.
• Locked until 59½. Early withdrawal means a 10% penalty plus taxes (with some exceptions).
• Taxed on withdrawal. Every dollar you pull out is taxed at ordinary income rates.
• No leverage. You invest $1, you get $1 of market exposure.
• Sequence-of-returns risk. A market crash right before retirement can devastate your portfolio.

The Real Estate Path

How It Works

You buy rental properties using leverage (mortgages), collect rent, build equity, benefit from appreciation, and use tax advantages unique to real estate. You reinvest cash flow and equity to acquire more properties over time.

The Numbers

Starting point:

• $40,000 initial investment (down payment + closing costs on first property)
• $12,000/year additional investment from savings
• Properties purchased: 1 in year 1, adding 1 every 2 years using accumulated equity and savings

Property assumptions:

• Average purchase price: $200,000
• Down payment: 20% ($40,000)
• Interest rate: 6.5% fixed, 30-year
• Monthly rent: $1,800 (increasing 3% annually)
• Annual appreciation: 3%
• Net cash flow per property: $300/month initially (growing with rent increases)
• Annual expenses: 50% of gross rent (including management)

Acquisition timeline:

At year 30: ~$3,800,000 in equity, $132,000/year in cash flow

And here's the kicker — several of your earliest properties will have their mortgages paid off or nearly so, dramatically increasing cash flow in later years.

The Tax Advantage

Unlike a 401(k), rental income is taxed favorably:

• Depreciation shelters a significant portion of rental income from taxes. At 12 properties, you could shield $60,000–$70,000 annually.
• Long-term capital gains rates apply when you sell (15–20%, not ordinary income rates of 22–37%).
• 1031 exchanges let you sell and reinvest without paying any capital gains tax.
• Step-up in basis at death. Your heirs inherit properties at current market value, wiping out all capital gains tax.

Effective tax rate on rental income with depreciation: often 0–15%, compared to 22%+ on 401(k) withdrawals.

Real Estate Strengths

• Leverage. $40,000 controls a $200,000 asset. A 3% appreciation on $200,000 is $6,000 — a 15% return on your $40,000 investment.
• Four income streams. Cash flow, appreciation, equity paydown, and tax benefits.
• Inflation hedge. Rents and property values rise with inflation. Your fixed-rate mortgage payment stays the same.
• Control. You choose the market, the property, the tenants, and the strategy.
• No age restrictions. Access your income anytime. No penalties.
• Tangible asset. Real estate has intrinsic value. It doesn't go to zero.

Real Estate Weaknesses

• Active management. Even with a property manager, it's not truly passive.
• Illiquidity. You can't sell a property in 5 minutes like a stock.
• Concentration risk. A single bad property or market can hurt significantly.
• Capital intensive. Each new property requires $30,000–$50,000 in down payment and reserves.
• Tenant risk. Bad tenants can cost thousands in damage, eviction, and lost rent.
• Market risk. Property values and rents can decline in specific markets.

The Head-to-Head Comparison

By pure wealth building, real estate wins — and it's not close.

The leverage effect is the single biggest differentiator. When you invest $40,000 in a 401(k), it grows at the market rate on $40,000. When you invest $40,000 in real estate, it grows at the market rate on $200,000. That 5:1 leverage multiplies every return.

Why Not Both?

Here's the honest answer: the smartest investors do both.

The optimal strategy:

1. Contribute enough to your 401(k) to get the full employer match. If your employer matches 50% up to 6%, contribute 6%. That match is a guaranteed 50–100% return. Don't leave it on the table.

2. Invest everything above the match into real estate. The additional $500–$1,000/month goes toward your next down payment. Real estate's leverage and tax advantages will outperform additional 401(k) contributions.

3. Use rental income to max out tax-advantaged accounts later. Once your portfolio generates significant cash flow, use it to fund a Roth IRA, HSA, or Solo 401(k) (if you qualify as a real estate professional).

This hybrid approach gives you:

• The guaranteed return of an employer match
• The leveraged growth of real estate
• Diversification across asset classes
• Tax optimization through multiple account types

The Argument for 401(k) Only

Real estate isn't for everyone. If any of these apply, a 401(k)-heavy approach might be better:

• You have zero interest in managing properties or learning real estate
• Your local market doesn't support cash flow and you don't want to invest remotely
• You value liquidity and simplicity above all else
• You're in a very high income tax bracket and the pre-tax 401(k) deduction is extremely valuable
• You're within 5 years of retirement and don't want to take on new debt

There's no shame in the index fund path. A 401(k) invested in a total stock market index fund has made millions of people wealthy. It's just slower and less tax-efficient than real estate at the same investment level.

The Argument for Real Estate Only

Some investors skip the 401(k) entirely (beyond the match). Their reasoning:

• Every dollar in a 401(k) is a dollar that can't be a down payment
• [Real estate cash flow](/blog/best-cities-for-rental-income-2026) is accessible now, not at 59½
• The tax benefits of real estate exceed the tax deferral of a 401(k)
• Leverage makes [real estate returns](/blog/best-cities-for-cash-flow-2026) 3–5x higher per dollar invested
• You're building an asset that produces income without depleting principal

This approach works best for investors who are committed to learning real estate, active in deal-finding, and comfortable with the hands-on nature of property management.

What the Data Says

A 2024 study by the Federal Reserve showed that real estate investors have a median net worth roughly 3x higher than non-real-estate-owning households, even when controlling for income levels. Homeownership alone is the single biggest driver of household wealth in America.

The S&P 500 has returned about 10% annually over the last 50 years (nominal). Real estate, when accounting for leverage, cash flow, tax benefits, and appreciation, has delivered 15–25% total returns for active investors.

The gap widens over time because of compounding on a leveraged base.

FAQs

Is real estate really better than a 401(k)?

For wealth building, real estate has significant advantages due to leverage, tax benefits, and multiple income streams. However, a 401(k) with an employer match offers a guaranteed return that's hard to beat. The best strategy for most people is to capture the employer match and invest additional savings in real estate.

What if the real estate market crashes?

Real estate markets do correct. The 2008 crash saw values drop 20–30% in many markets. However, if you're buying for cash flow (not speculation), you continue collecting rent through downturns. Rents dropped only 3–5% nationally during 2008–2010, while the stock market fell 50%.

Can I use my 401(k) to invest in real estate?

Yes, through a [self-directed IRA](/blog/dscr-loan-self-directed-ira) (rollover from 401k after leaving an employer) or a Solo 401(k) with a real estate option. You can also take a 401(k) loan (up to $50,000) to fund a down payment, though this carries risk.

What about Roth IRA vs. real estate?

A Roth IRA (tax-free withdrawals in retirement) is excellent and worth maxing out ($7,000/year in 2026) alongside [real estate investing](/blog/brrrr-strategy-guide). The Roth's tax-free growth complements real estate's tax-advantaged cash flow perfectly.

Don't I need a lot more money to invest in real estate than a 401(k)?

Not necessarily. A 401(k) contribution of $500/month over 3 years equals $18,000. That same $18,000 is a down payment on a house hack with an FHA loan. The entry points are comparable — real estate just requires saving in a lump sum rather than dollar-cost averaging.

What about REITs as a middle ground?

REITs ([Real Estate Investment](/blog/dscr-loan-fix-and-flip) Trusts) offer stock market-like liquidity with real estate exposure. They're a fine diversification tool. But REITs don't offer leverage, direct tax benefits (no depreciation pass-through in taxable accounts), or the control of direct ownership. Returns typically fall between stocks and direct real estate.

The Bottom Line

A 401(k) is a good retirement tool. Real estate is a great wealth-building tool. Over 30 years with the same starting capital:

• 401(k) only: ~$1.08M after tax, $3,590/month retirement income
• Real estate only: ~$3.8M in equity, $11,000/month retirement income
• Both (optimized): ~$4.5M+ combined, $13,000+/month retirement income

The 401(k) gives you simplicity. Real estate gives you leverage, control, tax advantages, and significantly more wealth.

For most people willing to put in the work, the answer isn't either/or. It's employer match first, then every extra dollar into real estate. That combination builds generational wealth.
