Property Tax Shock: Why Bills Are Rising & How to Fight Back

You opened your property tax assessment, saw the number, and said something you can't repeat on a podcast. I've been there. Last spring, one of my rentals in Memphis got hit with a 23% increase. Not 2.3%. Twenty-three percent. On a property I hadn't touched in two years.

Here's the thing — you don't have to just take it. There's a process. It works. And most investors never bother.

I'm Martin Maxwell, and this is 5-Minute PRIME. Let's talk about why your tax bill is climbing and exactly how to push back.

The Numbers Behind the Spike

The national average property tax increase in 2024 was 4.1%. Doesn't sound terrible — until you realize that's an average. Some markets barely moved. Others got wrecked.

Cook County, Illinois? Reassessments pushed bills up 17% in certain townships. Parts of Harris County, Texas saw 20% jumps after post-pandemic valuations finally caught up. Maricopa County, Arizona — same story. Assessors spent the last three years playing catch-up on home values that surged during 2021 and 2022, and now they're sending the bill.

Here's what that looks like on a real property. Say you own a duplex in Cleveland assessed at $185,000. Your old tax bill was $4,218 a year. After a 19% reassessment bump, you're now assessed at $220,150 — and your tax bill jumps to $5,019. That's $801 a year you didn't plan for. On a property that might cash flow $3,600 annually, that's 22% of your profit wiped out. Just like that.

And here's the kicker — this hits your NOI directly. Property taxes are an operating expense. When they spike, your net operating income drops dollar-for-dollar. Your cap rate compresses. Your deal looks worse on paper even though nothing changed about the property itself.

The Appeal Window You Can't Miss

Every jurisdiction gives you a window to challenge your assessment. In most counties, it's 30 to 90 days from the date the assessment notice is mailed. Not from when you opened it. Not from when you finally noticed it buried under junk mail. From the day they mailed it.

Miss that window and you're stuck paying the new number for an entire year. Maybe longer.

So step one — and I mean the day you get that notice — check the deadline. It's printed right on the form. Circle it. Set a phone reminder. Tape the notice to your fridge if you have to.

Tennessee gives you about 45 days. Texas? May 15 or 30 days after the notice — whichever comes later. Ohio's different — you file between January 1 and March 31 for the previous year's valuation. Every state has its own rules. Look it up.

Building Your Case

Here's where most people go wrong. They walk into the appeal hearing and say, "My taxes are too high." That's not an argument. That's a complaint.

You need three things.

Comparable sales. Pull three to five properties that sold within half a mile and the last 12 months. They need to match yours — similar size, age, condition. If your property is a 1,400-square-foot duplex built in 1978, don't pull a 2,200-square-foot new build as a comp. The assessor will throw it out.

Here's your line: "These comparable properties sold for $165,000, $172,000, and $168,000. My property is assessed at $220,150. The market doesn't support that number."

Condition evidence. Take photos of deferred maintenance, aging systems, and anything that drags value down. Foundation cracks. A 22-year-old roof. That original HVAC unit the seller swore had "a few good years left" — spoiler, it doesn't. Capital expenditures you haven't made yet are proof that the property isn't worth what they claim.

Error documentation. You'd be surprised how often assessors get basic facts wrong. Square footage off by 200 feet. An extra bathroom that doesn't exist. I once pulled a property card that listed a "finished basement" — it was raw concrete with a drain in the floor. Pull your property card from the assessor's website and check every line.

Hire a Pro — On Contingency

If your appeal involves more than a few thousand dollars in potential savings, hire a property tax attorney or consultant. Most work on contingency — they take 25-40% of your first-year savings, and if they don't win, you pay nothing.

On that Cleveland duplex, if an attorney gets your assessment knocked down from $220,150 to $190,000, your annual tax bill drops by roughly $687. The attorney takes $250 or so. You keep the rest — and the lower assessment sticks for the next reassessment cycle. That's savings you collect year after year for one afternoon of work.

I've done this three times across different states. Won two, lost one. The two wins saved me a combined $1,340 annually. Not glamorous. But it took me about two hours total, and the attorney handled the hearing.

Budgeting for the Long Game

Here's what I tell every investor in my property management guide: budget 1-2% of property value annually for property taxes. Not the current bill — the percentage of value. Assessments go up. Always have, always will. And if you're underwriting deals assuming today's tax number stays flat, you're lying to yourself.

Run your deal analysis with a 5% annual tax escalation baked in. If the deal still works at that assumption, you're solid. If a 5% tax bump kills your cash flow, the deal was too thin to begin with.

And here's the part most investors forget: property taxes are the one expense you can actually fight. You can't argue with the water company. Good luck negotiating your insurance premium at a hearing. But property taxes? You can walk into a county board of equalization with three comps and a stack of photos and walk out paying less.

Your Move

Pull up your most recent property tax assessment for every rental you own. Check three things:

1. Is the assessed value reasonable? Compare it to recent sales in your area. If it's 15% or more above market, you've got a case.
2. Is the property description accurate? Check square footage, bedroom count, lot size, and condition ratings. One error is all you need.
3. When's the deadline? Mark it. Don't let it pass. Missing that deadline is throwing money away — and that's money you'll never see again.

You earned that cash flow. Don't let a lazy reassessment take it from you.
