Rent vs. buy: the real math
Not propaganda in either direction. Owning isn't automatically winning and renting isn't automatically losing — but the comparison most people run in their heads is missing half the variables. Here's the honest version.
The comparison everyone gets wrong
The mental math is usually: "my rent is $1,650 and a mortgage would be $2,100, so renting wins." That compares one full number to one partial number. The real comparison is:
- Renting costs: rent + renter's insurance + annual increases you don't control.
- Owning costs: principal + interest + taxes + insurance + maintenance (budget ~1% of home value/year) − the principal part, which is money you keep.
Every mortgage payment has a slice that pays down your own loan. Early on it's a thin slice — a few hundred dollars a month — but it's your few hundred dollars, building equity instead of leaving forever. Rent's equity slice is $0, every month, by design.
A Minnesota-shaped example
Illustrative numbers, not a quote:
| Renting | Owning ($285k townhome) | |
|---|---|---|
| Monthly out of pocket | $1,650 rent | ~$2,150 PITI + MI |
| Going to someone else | $1,650 | ~$1,800 (interest, taxes, insurance) |
| Going to you (principal) | $0 | ~$350 and rising every month |
| Annual increase | Whatever the landlord says | Fixed P&I for 30 years; taxes/insurance drift |
| Maintenance | $0 (call the landlord) | Budget ~$200/mo |
Squint at that and the honest gap between renting and owning here isn't $500/month — it's closer to $350/month once principal is counted, before any appreciation, tax effects, or the fact that the rent number won't stay $1,650. And that's the point: the gap is a real number you can calculate, not a vibe.
The actual wall: cash at closing
For most first-time buyers the monthly payment was never the real blocker — the upfront cash was. Down payment plus closing costs on a $285k home can be $17k+ if you do it the hard way. This is precisely the wall that Minnesota Housing DPA loans and county and city assistance were built to lower — sometimes down to a four-figure number, occasionally lower.
When renting genuinely wins
Honesty corner. Renting is the right call when:
- You might move within ~2–3 years — transaction costs need time to amortize.
- Your income is unstable and a repair bill would be a crisis.
- You'd have to drain every dollar of savings to close, leaving no emergency fund.
- Rent in your area is dramatically below the cost of comparable ownership and you invest the difference (actually invest it, not intend to).
A good loan officer will tell you when you're in one of those categories. Zach's favorite outcome is a buyer who closes at the right time, not the soonest one — those people send referrals for a decade.
How to run your version
- Get your realistic price range and payment (start with the calculator, confirm with Zach).
- Subtract the estimated principal portion from the payment to get your true monthly cost.
- Compare that against your rent's trajectory, not just today's rent.
- Get your assistance stack priced — cash-at-closing changes the whole equation.
