Myth

Only 9.5% of your Year 1 housing cost builds equity

On a $1.2M Bay Area home at 6.8%, most of your payment goes to interest, taxes, and maintenance. Here's the full cost breakdown — and when renting wins.

TL;DR

No. When you buy, a huge chunk of your payment goes to interest, taxes, insurance, and maintenance — none of which build equity. Renters who invest the difference often come out ahead, especially in expensive markets or if you move within 5–7 years.

The myth everyone repeats

"Why pay someone else's mortgage?" It's the most common argument for buying. The logic seems airtight: rent is 100% gone, but a mortgage payment builds equity. Therefore renting = waste.

But this framing has a massive blind spot. It compares all of rent to the full mortgage payment — as if every dollar of that payment goes into your pocket. It doesn't.

What actually happens when you buy

Let's take a real example. A $1.2M home in the Bay Area, 20% down, 6.8% rate — a typical 2026 scenario (the 30-year average was 6.71% in early September 2026, per Freddie Mac).

Monthly cost of owning (Year 1)
Mortgage payment $6,260
→ Interest (doesn't build equity) −$5,440
→ Principal (builds equity) $820
Property tax −$1,200
Insurance −$200
Maintenance (1% rule) −$1,000
Total monthly cost $8,660
Amount that builds equity $820 (9.5%)

Read that last line again. In Year 1, only 9.5% of your total housing cost builds equity. The other 90.5% is "thrown away" — to interest, taxes, insurance, and maintenance. That's worse than renting, where at least you're not paying property tax and maintenance on top.

The money you don't see

There's another cost buyers rarely count: the opportunity cost of the down payment.

$240K
Down payment (20% of $1.2M)
$16,800
Annual return at 7% if invested

That $240K sitting in your house earns you home appreciation (maybe 3–4%/yr historically). If invested in a diversified index fund, the historical average is closer to 7–10%/yr. Over 7 years, that gap compounds into serious money.

The real comparison

When you compare honestly — total cost of owning vs. renting + investing the difference — the picture shifts dramatically. The key variables:

70–80%
Of Year 1 mortgage goes to interest
7+ yrs
Typical breakeven horizon

When buying wins

Buying tends to come out ahead when you stay 7+ years, when the price-to-rent ratio is below 20, when mortgage rates are low, and when you wouldn't invest the savings otherwise (let's be honest, some people wouldn't).

When renting wins

Renting often wins in expensive markets (SF, NYC) where price-to-rent ratios are 30+, when you might move within 5 years (closing costs and selling fees eat your equity), when rates are high (like right now), and when you're disciplined enough to invest the difference.

The Bottom Line
Renting isn't throwing money away — it's paying for flexibility, zero maintenance, and the opportunity to invest the difference. Buying isn't always building wealth — sometimes it's paying a bank 6.8% for the privilege of also paying property tax.

The real answer depends on your numbers — your market, your timeline, your discipline. Don't let a bumper-sticker slogan make a $1M decision for you.
