The Squeeze Nobody's Talking About
You raised rents this year. Maybe 3%, maybe 5% if you got aggressive. Felt good. Then your insurance renewal hit.
Up 19%.
That's not a typo. According to S&P Global, U.S. property insurance premiums rose 19% in 2024 alone — the fourth consecutive year of double-digit increases. Meanwhile, national rent growth hovered between 3% and 5%. Run that math across a 10-unit portfolio and the picture gets ugly fast.
Say your portfolio collects $15,000/month in rent. A 4% rent increase puts $7,200 more in your pocket annually. But if your combined premiums jumped from $18,000 to $21,420, that's $3,420 gone — nearly half your rent gains, consumed by a single line item you probably didn't even negotiate.
Insurance is quietly becoming the biggest threat to small landlord margins. And most owners are doing almost nothing about it.
Why Insurance Costs Are Outrunning Everything
This isn't just "inflation." Several structural forces are compounding simultaneously, and they're not going away.
Climate risk repricing. Insurers aren't stupid. Wildfire seasons are longer. Hurricane zones are expanding. Hail damage in Texas and the Midwest has become an annual certainty, not a freak event. Carriers are repricing risk across entire regions — not just disaster zones. If you own property within 200 miles of a coast or in a hail corridor, you're paying the bill for everyone's claims.
Reinsurance costs. The companies that insure your insurer have jacked up their rates. Those costs get passed directly to you. This is why even landlords in "safe" markets are seeing 10-15% increases — the global reinsurance market doesn't care that your duplex in Ohio hasn't filed a claim in a decade.
Replacement cost inflation. Building materials are up 30%+ since 2020. Labor costs haven't come back down. Your insurer's exposure — the cost to rebuild your property if it burns down — has grown dramatically, and your premium reflects that. Even if your property hasn't changed, the cost to replace it has.
Carrier exits. State Farm stopped writing new homeowner policies in California. Farmers Insurance pulled out of Florida. When carriers leave a state, competition drops and the remaining insurers charge whatever they want. If you're in one of these markets, you know exactly what this feels like.
Here's the uncomfortable truth: most of these trends are accelerating, not stabilizing. Hoping premiums come back down is not a strategy.
The Real Cost: What Insurance Does to Your NOI
Insurance isn't just an annoying line item. It's a direct hit to your net operating income — the number that determines what your property is actually worth.
Let's say you own a small apartment building generating $8,000/month in rent. Your annual insurance was $4,800, which is reasonable at about 5% of gross rent. Then it jumped to $6,200. That $1,400 increase drops your NOI by $1,400 — and at a 7% cap rate, that means your property's market value just dropped by $20,000. From one renewal letter.
Now multiply that across multiple properties. A landlord with a 15-unit portfolio could easily see $5,000-$8,000 in additional insurance costs per year. That's not just less cash flow. That's a meaningful reduction in what the portfolio is worth on paper — and what a buyer would pay for it.
If you track rent increases religiously but don't track insurance as a percentage of gross rent, you're measuring the wrong thing.
What You Can Actually Do About It
You can't control wildfire risk or reinsurance markets. But you can control how you manage insurance as an expense category. Most landlords leave thousands on the table because they treat insurance as a fixed cost. It's not. It's a negotiable, benchmarkable, manageable expense — if you treat it like one.
1. Know Your Numbers Per Property
Step one is embarrassingly simple, and most landlords haven't done it: know what you're paying per property, per unit, as a percentage of gross rent.
Industry benchmarks vary by market and property type, but most residential rental properties should fall between 4% and 8% of gross rent for insurance. If you're above 8%, something is wrong — either you're overpaying, you're in a high-risk zone that needs a different strategy, or your coverage is misaligned with your actual exposure.
You can't optimize what you don't measure. Pull every policy. Build a simple spreadsheet. See where you actually stand.
2. Shop Every Renewal — Every Single One
Auto-renewing insurance is the most expensive habit in property management. Carriers count on your inertia. They know most landlords will grumble at the increase and pay it anyway.
Get quotes from at least three carriers 90 days before every renewal. Not 30 days — 90. This gives you time to actually negotiate, compare coverage (not just price), and switch if needed. Yes, it's tedious. But a single afternoon of comparison shopping can save $500-$1,500 per property per year.
For landlords with 5+ properties, an independent insurance broker who specializes in investment properties is worth their weight in gold. They shop the market for you and have access to carriers you can't reach directly.
3. Bundle Strategically
Carriers give multi-policy discounts — typically 10-15% — but only if you ask. If you have three properties with three different carriers, you're leaving the volume discount on the table.
The exception: don't bundle if it means accepting worse coverage or a financially shaky carrier just for a discount. A 12% savings means nothing if the carrier slow-pays your claim or goes insolvent.
4. Raise Deductibles Intentionally
Most landlords carry $1,000 deductibles because that's the default. Moving to a $2,500 or $5,000 deductible can reduce premiums 15-25%. On a property where insurance costs $4,000/year, that's $600-$1,000 in annual savings.
The math: you're self-insuring the first $2,500-$5,000 of any claim. If you have reserves (and you should), this is often the right trade. You're paying less every year in exchange for paying more in the rare event of a small claim. Most experienced landlords who track their claims history realize they file a claim once every 5-10 years per property. The premium savings compound every year between claims.
5. Audit Your Coverage — You're Probably Misinsured
Overpaying isn't the only risk. Being underinsured is worse, and it's shockingly common.
Check your replacement cost estimate against current construction costs in your market. If your policy says $200,000 replacement cost but it would actually cost $280,000 to rebuild, you're carrying a gap that could financially destroy you. Conversely, if your replacement cost is inflated beyond reality, you're overpaying for coverage you'd never collect.
Also check: Does your policy cover loss of rental income during repairs? For how long? What's excluded? Many landlords discover their coverage gaps only when they file a claim. That's the worst time to learn.
The Portfolio View Changes Everything
When you manage insurance property by property, you're playing defense on ten separate fronts. You miss the patterns. You don't notice that your Florida properties are subsidizing your Midwest ones. You can't see that consolidating carriers would save you $3,000/year across the portfolio.
Institutional investors don't manage insurance this way. They look at insurance as a portfolio-level expense category — benchmarked, monitored, and actively managed just like rent pricing or maintenance spending. They track premium-to-rent ratios across every asset. They know which properties are outliers. They calendar every renewal 90 days out.
You don't need an institutional risk management team to think this way. You need visibility. One place where you can see every policy, every renewal date, every premium as a percentage of income — across your entire portfolio.
Stop Hoping. Start Managing.
Trenly tracks your insurance policies alongside every other expense, flags renewal dates before they sneak up on you, and shows you exactly what insurance is costing you as a percentage of gross rent — per property and across your portfolio. Because the landlords who treat insurance as a managed expense are the ones who keep their margins while everyone else watches them erode.
Insurance premiums aren't coming back down. But your margins don't have to follow them.
The landlords who win the next five years won't be the ones who collected the most rent. They'll be the ones who controlled the costs that everyone else ignored.
