What a $750K Home in Los Angeles Really Costs Per Month at 6.5%: PMI, Amortization, and When to Buy Points
What a $750K Home in Los Angeles Really Costs Per Month at 6.5%: PMI, Amortization, and When to Buy Points
You're renting a 3-bedroom in Los Angeles for $3,400/month. A similar house just hit the market at $750K. You've got $75,000 saved — exactly 10% down. You pull up a mortgage calculator, see $4,267/month, and think: $867 more than rent. That's manageable.
Then you actually buy the house. And three months in you're staring at a bank statement wondering how "manageable" became $6,200/month.
This post is the number-crunching session you should have had before you signed anything. We're going to break down the true monthly cost of that $750K home — PMI, amortization, property taxes, insurance, maintenance — and then tackle the question nobody answers clearly: should you buy points at today's rates, and does it actually save you money?
Today's Rate Environment: Volatile, But Slightly Better
Mortgage rates fell on March 26, 2026, according to NerdWallet's daily rate tracker — offering what the outlet called "a bit of relief." But the qualifier is important: rates could rise again just as quickly. We've been in a rate environment that swings 10–20 basis points in a single week, which matters enormously when you're trying to decide whether to lock, float, or buy points.
For this analysis, we're using 6.5% on a 30-year fixed — a conservative but realistic assumption that doesn't require you to time a rate dip perfectly. If you're reading this on a day when rates dip to 6.3%, the math shifts in your favor by about $90/month. Meaningful, but not transformative.
The Mortgage Payment Everyone Calculates
Loan details:
- Home price: $750,000
- Down payment: $75,000 (10%)
- Loan amount: $675,000
- Rate: 6.5% / 30-year fixed
- Monthly P&I: $4,267
That's the number most people stop at. Here's where the math gets uncomfortable.
What You're Actually Paying Each Month
| Cost Component | Monthly Amount |
|---|---|
| Principal & Interest | $4,267 |
| PMI (at 10% down, ~0.7% annually) | $394 |
| Property Tax (LA County ~1.25%) | $781 |
| Homeowners Insurance | $167 |
| Maintenance Reserve (1% annually) | $625 |
| Total True Monthly Cost | $6,234 |
That's $2,834/month more than your $3,400 rent. Not $867.
The single biggest surprise for most buyers is that maintenance reserve. One percent of $750K is $7,500/year — and that's actually conservative for LA, where deferred maintenance in a hot market often means the prior owner skipped things. Roofs, HVAC, plumbing: these bills arrive on their own schedule.
This is the kind of breakdown Torvani runs automatically — so instead of building this table yourself at midnight, you're working from a complete picture before you make an offer.
The Amortization Reality Check: Where Your Money Actually Goes
Here's something your mortgage calculator won't show you prominently: in year one, 86% of every payment is pure interest.
Let's break down the very first mortgage payment on that $675K loan at 6.5%:
- Interest: $675,000 × (6.5% ÷ 12) = $3,656
- Principal: $4,267 − $3,656 = $611
You paid $4,267. You own $611 more of your house. The bank kept $3,656.
Now let's look at where you stand after 5 years of payments (60 payments × $4,267 = $256,020 total paid):
- Remaining loan balance: approximately $631,900
- Principal paid down: ~$43,100
- Interest paid: ~$212,900
You spent a quarter million dollars and knocked $43K off the loan. The rest went to the lender. This is not a reason to avoid buying — equity is still equity, and you own the asset — but it is a reason to stop treating a mortgage payment as if it's equivalent to investing.
The amortization curve does improve over time. By year 15, roughly half your payment goes to principal. But for most people who move every 7–10 years, they exit the loan precisely when the interest-heavy early years are eating most of their payment.
PMI: The $394/Month Tax on Not Having 20% Down
Private mortgage insurance isn't permanent, but "not permanent" and "cheap" aren't the same thing.
At 0.7% annually on a $675,000 loan, PMI costs $394/month — or $4,728/year. It sticks around until your loan-to-value ratio drops below 80%, meaning you need your outstanding balance under $600,000 (80% of the $750K purchase price).
Starting at $675K, paying down to $600K through normal amortization at 6.5% takes approximately 10 years. That's $47,280 in PMI payments before you can cancel it by the calendar.
Your two escape routes are faster:
-
Appreciation: If your home rises to ~$844,000, your $675K loan is suddenly 80% LTV — and you can request PMI cancellation. In LA, that's plausible over 3–5 years if appreciation holds. But don't count on it.
-
Extra principal payments: Putting an extra $500/month toward principal can accelerate your PMI removal by 3–4 years, saving roughly $14,000-$19,000 in total PMI premiums.
The lesson: if you're choosing between 10% and 20% down, the PMI math often tips toward saving longer — unless you're in a market moving fast enough that waiting costs you more in appreciation than PMI saves you.
Should You Buy Points? The Break-Even Math
At today's rates, lenders are quoting roughly 1 point (1% of loan amount) to buy the rate down by 0.25%.
On a $675,000 loan:
- 1 point costs: $6,750
- Rate reduction: 6.5% → 6.25%
- New monthly payment: $4,157 (down from $4,267)
- Monthly savings: $110
Break-even: $6,750 ÷ $110 = 61 months (5.1 years)
If you stay in the home longer than 5 years, buying a point pays off. If you sell or refinance before then — which most homeowners do — you've lost money.
Here's where rate volatility changes the calculation: if rates drop to 5.5–6% in the next 2–3 years and you refinance, you've thrown away $6,750 on a point that became irrelevant. Conversely, if rates stay elevated or climb, locking in 6.25% today looks smart in hindsight.
The verdict on points: Only buy them if (a) you have a solid reason to believe you'll stay past the break-even, and (b) you genuinely believe rates won't fall far enough to trigger a refinance before then. In the current environment, that's a harder call than usual.
You can model your own points break-even at different rate scenarios at Torvani — it accounts for the probability of refinancing, not just the simple payback period.
Refinancing: Your Rate Insurance Policy
One underappreciated aspect of locking in a 30-year fixed today: refinancing is always an option if rates drop. The question is whether the math works.
Refinancing typically costs 2–3% of the loan amount in closing costs — roughly $13,500–$20,250 on a $675K loan. At that cost, a refinance from 6.5% to 5.75% (saving ~$320/month) breaks even in 42–63 months. That's another calculation that depends entirely on how long you stay.
The broader point: treating your current rate as permanent is a mistake. But treating a future refi as free money is also a mistake. The closing costs are real, the timeline matters, and every rate dip triggers a fresh break-even calculation.
The Context These Numbers Live In
LA's Affordability Trap Cuts Both Ways
Realtor.com's recent reporting on affordability traps in pricey metros like Los Angeles highlights a counterintuitive reality: long-term renters in below-market units are financially anchored to their current apartments, unable to afford both a move within the rental market and the costs of buying. This creates a bifurcated renter class — those in stable, affordable units who may rationally choose to stay put, and newer renters paying market rates who are closer to the buy-or-wait tipping point.
If you're in a rent-controlled unit paying $2,400/month in a neighborhood where comparable rentals now go for $3,800, the calculus is completely different than if you just moved to LA and signed a $3,400/month lease. Your personal rental baseline dramatically changes when buying actually pencils out.

The New Crypto Mortgage Option (Read the Fine Print)
Better.com and Coinbase recently launched a product that lets qualified borrowers pledge Bitcoin or USDC as collateral for a conforming mortgage down payment — without selling their crypto. The pitch is appealing: keep your crypto exposure, get the house.
The risk is significant. Crypto used as collateral is subject to margin calls if prices drop — meaning a Bitcoin crash could force you to liquidate at the worst possible moment or lose the collateral position. This isn't a reason to dismiss the product entirely, but it's absolutely a reason to stress-test your numbers before pledging volatile assets as collateral on a 30-year commitment.
NYC's Policy Risk Is a Real Cost Category
New York is considering a transfer tax targeting high-value home sales — and Realtor.com's coverage notes the ripple effects could extend well beyond luxury properties. This is a reminder that tax policy is a legitimate variable in ownership math, not just background noise. NYC buyers should factor in both the current transfer tax structure and proposed changes when calculating true transaction costs.
For West Coast buyers, California's Proposition 19 has its own implications for inherited property and reassessment. These aren't hypotheticals — they're line items in your real ownership cost.
Renting vs. Buying in LA: What the Numbers Actually Say
| Scenario | Monthly Out-of-Pocket | 5-Year Total Cost |
|---|---|---|
| Renting at $3,400/month | $3,400 | ~$204,000 |
| Buying $750K at 6.5%, 10% down | $6,234 | ~$374,000 + $75K down |
| Buying $750K at 6.5%, 20% down | $5,840 (no PMI) | ~$350,000 + $150K down |
Buying costs more per month in the early years. What you're purchasing is the right to benefit from appreciation, build equity over time, and lock in your housing cost against future rent increases. Whether that trade-off is worth it depends on your appreciation assumptions, your timeline, and what you could earn by investing the down payment instead.
In LA's current market, the breakeven timeline on a rent-vs-buy comparison stretches longer than most buyers expect — and that's before you model what your down payment earns in the market versus sitting in home equity.
The Question You Need to Answer for Yourself
Here's what the mortgage math tells you: buying a $750K home in LA at 6.5% with 10% down costs approximately $6,234/month all-in, not $4,267. PMI adds nearly $400 until you hit 80% LTV. Amortization means you're paying mostly interest for years. Points break even at 5.1 years. Refinancing isn't free.
None of this means don't buy. It means buy with accurate numbers, not the payment your lender quoted you.
Your city, your down payment amount, your rental alternative, your appreciation expectations, your timeline, and your risk tolerance all change this math significantly. The $750K LA scenario is illustrative — your scenario is specific.
Run your own numbers at Torvani. Model the PMI removal timeline, the points break-even at different rate assumptions, the opportunity cost of your down payment, and the true month-by-month comparison against your actual rent. The spreadsheet you build in 20 minutes could save you from a 30-year decision made on incomplete math.
