"Renting is throwing money away" is one of those things people repeat so often it feels like financial common sense. It is not. It is a half-truth that worked for a generation when rates were 3.5% and home prices grew faster than wages, and it broke sometime around 2022. With 30-year fixed rates sitting near 6.5% and home prices still elevated in most metros, the honest math now often favors renting, depending on the city and how long you plan to stay. This piece walks through the math that actually answers the question, not the vibes.

The framing problem

Renting is not "throwing money away" any more than buying groceries is throwing money away. You are paying for a service: shelter, maintenance handled by someone else, geographic flexibility. Buying is also not "paying yourself." You are paying down a loan while also paying property tax, insurance, and maintenance, all of which are gone forever the same way rent is.

The honest comparison is not rent-versus-mortgage. It is rent-versus- the-true-cost-of-ownership. And the true cost of ownership includes five things almost nobody adds up properly.

The 5% rule (Ben Felix)

Ben Felix, a portfolio manager in Ottawa who has been publishing rigorous YouTube essays on personal finance for a decade, popularized a heuristic that cuts through most of the confusion: the unrecoverable cost of owning a home is roughly 5% of the home's value per year.

That 5% breaks down as:

  • ~1% property tax (varies wildly by state; could be 0.3% in Hawaii, 2.5% in parts of Texas or Illinois)
  • ~1% maintenance (roof, HVAC, plumbing, paint, appliances; spread over time, about 1% of home value annually)
  • ~3% cost of capital (the sum of mortgage interest on the borrowed portion and the opportunity cost of the down payment you could have invested)

The rule: if annual rent for an equivalent property is less than 5% of the purchase price, renting is mathematically cheaper. If annual rent is more than 5% of the purchase price, buying is mathematically cheaper, assuming equal everything else.

This is not a perfect rule. It does not account for appreciation assumptions, tax deductions, or your specific rate. But it gets you to the right answer 80% of the time in 30 seconds, which is why we use it as the first filter.

A 2026 scenario: $450,000 home vs. $2,800 rent

Let's work a real example for a couple looking at a $450,000 townhouse in a mid-size city (think Nashville, Minneapolis, Pittsburgh), with 20% down. Comparable rental for the same townhouse: $2,800 a month. Current 30-year rate: 6.5%.

Quick 5% rule check

5% of $450,000 is $22,500 per year, or $1,875 per month. The rent is $2,800. So by the 5% rule, buying wins. But only barely, and the 5% rule is a rough tool. Let's do the full math.

True cost of owning, year one

Purchase price:             $450,000
Down payment (20%):         $ 90,000
Loan amount:                $360,000
Rate:                       6.5% / 30-year fixed
Monthly P&I:                $2,275

Property tax (1.0%):        $  375 / month
Homeowners insurance:       $  130 / month
HOA (townhouse):            $  220 / month
Maintenance (1.0%/yr):      $  375 / month
                            ---------
Total monthly outflow:      $3,375

Less: principal paydown     -$ 340 / month (yr 1)
(this is "savings," sort of, in home equity)

Net monthly cost:           $3,035

Plus: opportunity cost on $90k down payment
at 7% long-run market return:   $  525 / month
(money that could be in VTSAX instead)

TRUE monthly cost of owning:    $3,560

The apples-to-apples comparison is $3,560 per month of true cost versus $2,800 per month of rent. Renting is about $760 a month cheaper, or $9,100 a year, in year one.

But that is year one. Rent typically rises 3% a year. Mortgage P&I stays flat (property tax, insurance, and maintenance rise, but not as fast as rent). By year 5 or 6, the two crossover, and after that, buying is cheaper on an ongoing basis. Plus, you have been building equity the whole time.

The breakeven question

The right question is not "which is cheaper today" but "at what point does buying catch up and pull ahead." That depends on:

  1. Home appreciation (historical average: 3.5% nationally, but wildly local)
  2. Stock market return on what your down payment would have earned (historically ~7% real)
  3. Transaction costs of buying (~1% closing) and selling (~6% realtor + closing)
  4. Rent appreciation in your city

For our $450,000 example, with reasonable assumptions, the breakeven horizon is typically 5 to 7 years. If you plan to stay less than 5 years, renting wins almost always. If you plan to stay 10+ years, buying usually wins. In between is the murky zone where it depends on specifics.

The transaction costs are the thing that kills short-term buying. When you buy and sell a $450,000 home, roughly $32,000 evaporates in closing costs, realtor commissions, and transfer taxes. You have to live there long enough for appreciation and principal paydown to cover that.

Where the "buy" case still wins cleanly

We are not anti-buying. We are anti-assumption. There are clear scenarios where buying is the right call even at today's rates.

You plan to stay 7+ years

Time is the biggest lever. Transaction costs amortize, appreciation accrues, and you lock in housing costs that rent inflation cannot touch.

You need stability more than flexibility

Kids in a school district you love, a spouse with tenure, a local family business. The ability to paint the walls, renovate the kitchen, not be displaced when a landlord sells. These have real non-financial value. If you would pay $400 a month for that stability, your effective breakeven horizon shrinks.

You want forced savings

For people who struggle to save voluntarily, a mortgage is a commitment device. The principal portion of the payment is essentially forced savings you cannot skip without losing your home. This is a real benefit for some people, and real people include us at various points in our lives. It is not dumb to buy a home because you know you will not save otherwise.

You live in a sub-4% rent-to-price market

Parts of the Midwest, parts of the Sun Belt outside the major metros, and some rust belt cities have rent-to-price ratios well above 6%, meaning the 5% rule clearly favors buying. If rent on an equivalent house would be $2,400 and the purchase price is $300,000, that is 9.6% rent-to-price, and buying is obviously right. These markets exist. They are just mostly not the ones getting written about.

Where renting still wins, even after years

Conversely, in high-cost coastal metros with rent-to-price ratios below 4%, renting can beat buying even across 10+ year horizons. San Francisco, parts of Manhattan and Brooklyn, coastal Los Angeles, and Seattle all fit this pattern. A $1.8M home in Palo Alto that would rent for $5,500 a month is 3.7% rent-to-price, and the full math on that deal is brutal for buyers unless appreciation dramatically outruns historical norms.

The Rocket Mortgage and Zillow rent-vs-buy calculators are fine, but we usually end up rolling our own spreadsheet for any specific deal. The inputs that matter most are your actual expected holding period, the actual local property tax rate, and a realistic maintenance assumption (1% of home value is a median; older homes run higher).

The tax angle, briefly

The mortgage interest deduction used to tilt the math toward buying. Since the 2017 tax law doubled the standard deduction, most homeowners no longer itemize, which means the interest deduction often provides zero actual tax benefit. Roughly 10% of filers itemize now, down from 30% pre-2018. Do not assume you will get a tax break; run your numbers with and without and see if you actually clear the standard deduction.

What we'd actually do

Run the 5% rule first. If annual rent is less than 4% of comparable purchase price, rent and invest the difference into VTI or VTSAX in a taxable brokerage. If it is above 6%, buy when you are ready. If it is between 4% and 6%, the deciding factor is your honest expected time horizon. Under 5 years, rent. Over 7 years with stable life circumstances, buy. Whatever you decide, do not let "throwing money away on rent" or "a home is the best investment you will ever make" push you around. Both are slogans. Slogans do not build wealth. Math does.
