Private School vs. a Better School District With Mortgage Rates Above 7%: $298,000 in Tuition vs. a $90,000 House Premium
Say you're weighing two options. One is $18,500 a year for private school. The other is a house in a stronger public district that costs $90,000 more than the house you'd otherwise buy. Or you rent, and you're wondering whether any of the house math applies to you.
Mortgage rates are why this is harder right now. NerdWallet's Mortgage Rates Today, Wednesday, September 23 reports that rates dropped on a glimmer of economic optimism from Iran, but they are still above 7%. That "easing but still above 7%" headline is where this comparison gets interesting.
Below I run both options head-to-head with a worked example. The dollar figures for tuition, premium, and ESA are illustrative assumptions I chose, not sourced data. The rate context and the article ideas come from the cited pieces. Your numbers will differ based on your specific situation, so treat this as a template, not a verdict.
The Two Options, Stated Plainly
Option A: Private school. You pay tuition every year for 13 years (K-12) in whatever housing you already have.
Option B: Pay for the district. You buy or rent in a district with stronger public schools and pay a housing premium instead of tuition.
Option C: Neither. You stay in your current district and send your kids to public school. This is the baseline, not a failure.
Most "private vs. public" arguments skip the fact that Option B has two very different versions depending on whether you own or rent. That's where the first article comes in.
What a Mortgage Editor Who Still Rents Teaches About the House Premium
NerdWallet's I Edit Mortgage Advice for a Living — and Still Rent follows a mortgage content editor who, at 54, chooses to rent. She weighs the real down payment cost, the returns she could earn by investing instead, and the true price of homeownership.
That reasoning transfers directly to school-district shopping. A district premium isn't just "the extra price of the house." It's:
- The down payment on the premium, which could otherwise be invested
- Interest on the premium at a rate that is still above 7%
- Property tax on the extra value
- Selling costs if you leave before the premium pays back
Worked example: carrying a $90,000 premium at about 7.05%
Assume (all illustrative):
- $90,000 premium over a comparable house in a weaker district
- 20% down on the premium: $18,000
- $72,000 financed at 7.05% over 30 years
- Property tax on the premium at 1.2% of value per year
- A 5% alternative return on the down payment
Here is what the premium costs over 13 years:
| Cost component | 13-year amount |
|---|---|
| Extra mortgage payment (about $481/month × 156 months) | about $75,100 |
| Of which principal paid (equity you keep) | about $14,900 |
| Of which interest paid | about $60,200 |
| Extra property tax (about $1,080/year) | about $14,000 |
| Foregone growth on the $18,000 down payment at 5% | about $15,900 |
| Carrying cost, excluding equity and appreciation | about $90,000 |
So the premium costs about $90,000 to carry over 13 years, which is coincidentally close to the premium's own price. If the premium holds its value when you sell, you get most of the $90,000 back, minus selling costs. If it doesn't, you don't.
Head-to-Head: $298,000 Tuition vs. a $90,000 Carrying Cost
Now the tuition side. Assume $18,500 in year one and 3.5% annual tuition growth, which is a plain assumption you should replace with your school's actual history.
The 13-year sum is 18,500 × ((1.035¹³ − 1) ÷ 0.035), which comes to about $298,000.
| Private school (one child) | District premium, owner | |
|---|---|---|
| 13-year cash outlay | about $298,000 | about $90,000 (carrying cost) |
| Average per year | about $22,900 | about $6,900 |
| Recoverable at the end | Nothing | Possibly the premium, less selling costs |
| Main risk | Tuition growth, job loss | Premium erodes, rates, moving early |
| Flexibility | Can switch schools any year | Locked in by a mortgage |
On raw cash, the district premium looks far cheaper. That's the reason many families default to it. But the table hides three caveats:
- A better district is not the same product as a private school. Class size, curriculum, religious instruction, and special needs services may be things you can't get from a district at any price.
- The premium option only exists if you can afford the extra house at all. At a rate still above 7%, the qualifying income for even a $72,000 extra loan matters.
- You may be paying the premium anyway. If you're buying a house regardless, you're choosing where, not whether. If you're a happy renter, it's a different question, which I'll cover next.
This is the kind of analysis Zuvelanti runs for you, so you don't have to build the spreadsheet yourself.

If You Rent: The Comparison Changes
The NerdWallet editor's case for renting is that the down payment and the ownership costs, invested elsewhere, can beat owning. Apply that to schools and you get a third route: rent in the stronger district.
Renters don't pay a mortgage premium. They pay a rent premium. That premium is a pure expense with no equity, but it also comes with no down payment, no property tax bill, no maintenance, and no selling costs. It's also easy to exit. If your child changes schools, you move at lease end.
Illustrative comparison, using a $400 per month rent premium:
- $400 × 12 × 13 = $62,400 over 13 years with flat rent
- If rent rises 3% a year, that's closer to $75,000
- Nothing recoverable at the end
The renter's district premium of $62,400 to $75,000 is in the same range as the owner's $90,000 carrying cost. The difference is that the owner may recover much of the premium. The renter recovers none, but never had $18,000 tied up and can leave freely.
Either way, all three options sit well below the $298,000 tuition figure for one child. That's the core insight: whether private school makes sense usually depends on what you get that a district can't provide, not on the price gap.
Two Kids: Where the Math Really Splits
Here's where the district route often wins outright. The premium is per household. Tuition is per child.
| One child | Two children (same 13 years, overlapping) | |
|---|---|---|
| Private tuition (illustrative) | about $298,000 | about $596,000 |
| District premium carry (owner) | about $90,000 | about $90,000 (same house) |
| Gap | about $208,000 | about $506,000 |
Staggered kids overlap for fewer than 13 years, so real two-child tuition may run somewhat lower, but the point holds: the house premium doesn't multiply, tuition does. Many private schools offer sibling discounts, which can narrow the gap. Ask for the actual discount schedule, not the brochure.
Our two-child analysis goes deeper here: Two Kids, 13 Years: Private School Tuition vs. School District House Premium.
ESA and Voucher Offsets
If your state has an ESA or voucher program, the tuition side changes. Suppose a hypothetical $7,000 per year for 13 years. That's $91,000 off the $298,000, leaving about $207,000 in tuition, which is still more than double the district carry cost, but a much narrower gap.
The catch is eligibility, caps, and whether the funds follow you if your child leaves the school. Some programs are income-tested, so check yours before you assume it applies.
The Costs Nobody Puts in the Comparison
1. Local costs that move your district's budget
NerdWallet's Data Centers Are a Potent, Bipartisan Battleground in the Midterms describes data centers becoming a rare bipartisan flashpoint in the 2026 midterms, with anticipated costs and local impact driving voter backlash nationwide.
Why does that belong in a school post? Because local development decisions can affect property taxes, utility costs, and the tax base that funds your district. If you're paying a premium for a district, spend ten minutes on what's planned nearby and how the district budget is funded. A premium is only worth what the district looks like in year 8, not year 1.
2. The budget leak: small, repeated purchases
NerdWallet's I Can't Stop Buying Surprise Bags is about a spending habit where you don't know what's inside until you open it. It's funny, but it's also a budget lesson.
A commitment like $22,900 a year in average tuition leaves less slack for small, unplanned spending. Illustrative example: $25 a week on surprise items is $1,300 a year, or $16,900 over 13 years. That's not going to decide the private-vs-public question. But if your budget only works with zero slack, the tuition commitment will squeeze it. A district premium has the same problem, since a mortgage payment is just as fixed.
3. Payment method and perks
NerdWallet reports in Chase Freedom Flex Ditches Foreign Transaction Fee, Cell Phone Insurance that the card is changing its benefits, with a heightened welcome bonus for a limited time. If you plan to pay tuition or fees by card for rewards, the benefits you counted on can change under you. Also check whether your school adds a processing fee for card payments, because that can wipe out the rewards. Build your comparison on the tuition bill, not on the perk.
College Admissions: Be Honest About What You Can Model
Many parents justify private school as a college admissions edge. The honest position: you can model a probability adjustment, but you should use a range and not a single number. In a scenario where private school adds a few percentage points to your child's odds at a selective school, whether that's worth a $208,000 gap depends on what the admission actually changes for your family, such as aid, career path, and the alternative in-state option.
I'm not going to hand you a made-up percentage. Ask the school for outcome data on students like yours, not the top 5%, and compare it with the district's outcomes.
A Decision Sequence You Can Run Tonight
- Get the real tuition schedule. Add fees, uniforms, transportation, and required giving. Then apply the school's actual 5-year tuition history for growth.
- Get the real premium. Compare two houses you'd actually buy, not averages. Price the loan at today's rate, still above 7%, not last year's.
- Decide owner vs. renter. Use the NerdWallet editor's logic: what else would your down payment earn?
- Add ESA or voucher offsets only if you've confirmed eligibility.
- Multiply by children, and check the sibling discount.
- Stress test. What if tuition grows 5%? What if you move in year 6? What if a parent loses income?
- Check what you can't buy in a district. If a private school offers something specific your child needs, the math changes.
And the honest possibility: for many families, Option C, staying put in public school, wins. It costs the least, and a solid budget beats an ambitious one. If you want a checklist version, see Private School or Public? The 5 Financial Thresholds That Reveal the Right Answer for Your Family in 2026.
Sensitivity: What Moves the Answer Most
In my worked example, these variables swing the result the most:
| Variable | Change | Effect |
|---|---|---|
| Tuition growth | 3.5% to 5% | 13-year tuition rises from about $298,000 to about $332,000 |
| Mortgage rate | 7.05% to 6.5% | Premium carrying cost falls by roughly $6,000 to $8,000 (estimate) |
| Time in house | 13 years to 6 years | Selling costs and unrecovered premium weigh far more |
| Number of kids | 1 to 2 | Tuition gap more than doubles, premium carry stays flat |
| ESA eligibility | $0 to $7,000/year | Tuition falls by about $91,000 |
The biggest lever isn't the mortgage rate; it's how many kids you have and how long you'll stay put. That's why a generic rule of thumb tends to fail: it can't know either one.
The Bottom Line
With a 7%+ mortgage rate, a $90,000 premium costs about $90,000 to carry over 13 years in our example. One child's private tuition costs about $298,000 in the same example. That's not a reason to rule out private school. It's a reason to know exactly what you're buying with the extra $208,000.
The next step is to plug your own tuition quote, your own house prices, and your own family size into the model. Zuvelanti runs that full 13-year comparison, including tuition growth, district premium, ESA offsets, and multi-child scaling, so you can see your break-even before you commit to either path. Try your own numbers, and let the math tell you which option is right for you.
