Key Takeaways:
Ownwell built a name on one promise: file a property tax appeal with zero upfront cost and only pay if it wins. That promise still holds for a landlord with two or three rentals in a state Ownwell covers. It gets shakier the moment your portfolio spans counties, states, or property types with different deadlines and different rules β a Texas duplex, a Georgia single-family rental, and a Florida condo don't run on the same calendar. The best Ownwell alternative for landlords in 2026 is TaxDrop if your portfolio crosses state lines or you want a flat-fee option instead of a percentage-based one; Ownwell remains a solid pick if you own a handful of properties in one of its covered states and want to stay fully hands-off.
TL;DR
- TaxDrop covers Texas, California, Georgia, Florida, New Jersey, and Maryland with either a licensed-consultant protest or a flat-fee self-serve packet.
- Ownwell works entirely on contingency across a broad multi-state footprint but has no flat-fee tier for landlords who want cost predictability.
- O'Connor & Associates is a deep-bench Texas-only option for landlords whose entire portfolio sits inside the state.
- DIY filing costs nothing but time, and it works in any county or state you own property in.
- 30-60% of properties nationally are over-assessed, yet only about 5% of owners ever appeal.
Why this matters for landlords
A landlord's tax exposure multiplies with every door. One over-assessed rental in Texas is an annoyance; five over-assessed rentals across three states is a recurring drag on cash flow every single tax cycle.
Appraisal districts and assessors don't visit most properties before mailing a value. Rental comps get missed, condition adjustments get skipped, and the burden sits on the owner to catch it. That's true whether you're filing a Texas protest with the county appraisal district or an appeal with a California assessor's office.
TaxDrop built its model around that reality: a licensed-consultant-led protest for Texas landlords, and a flat-fee self-serve appeal packet for landlords holding property in California, Georgia, Florida, New Jersey, and Maryland. Ownwell solves a piece of that problem. It doesn't solve all of it for a multi-state portfolio.

1. TaxDrop: best for landlords with properties in more than one state
TaxDrop splits its offer into two tiers on purpose. Full-service protest β a licensed consultant handling your case from filing to hearing β runs in 17 Texas counties. TaxDrop One, the flat-fee self-serve packet, covers 43 Texas counties plus California, Georgia, Florida, New Jersey, and Maryland.
That structure matters for a landlord holding a Texas rental and a Georgia rental in the same year. One property gets a consultant filing a protest with the appraisal district before the May 15 deadline. The other gets a self-serve appeal packet built around Georgia's Board of Tax Assessors process and its roughly 45-day window from the Annual Notice of Assessment.
Where TaxDrop shines:
- Full-service protest charges nothing unless your assessment goes down β no reduction, no fee
- Flat-fee self-serve packet gives you a fixed cost regardless of how large the reduction turns out to be
- Covers six states with terminology and deadlines matched to each one, not a single generic process
- A free instant analysis flags over-assessment in under 2 minutes before you commit to anything
Where TaxDrop falls short:
- Full-service, consultant-led protest is Texas-only β landlords with California, Georgia, Florida, New Jersey, or Maryland rentals get the self-serve packet, not a licensed consultant
- New Jersey filings carry a non-refundable county filing cost paid upfront, unlike the other five states
Best for: landlords who want either a no-fee-unless-it-wins Texas protest or a flat-fee appeal packet for out-of-state rentals, and who'd rather not run five filings through five different vendors.

Verdict: Buy if you own rentals in two or more of the six states TaxDrop covers.
2. Ownwell: best for a small, single-state rental portfolio
Ownwell's real strength is simplicity. One contingency-fee agreement, one dashboard, no money out of pocket until a reduction lands. For a landlord with two rentals in the same state, that's genuinely low-friction.
The ceiling shows up with scale. A landlord managing eight rentals across three states with three deadlines and three filing bodies is asking one contingency process to flex in ways it wasn't built for β and there's no flat-fee tier for owners who'd rather pay a fixed cost than a percentage of the win.
Where Ownwell shines:
- No upfront cost β you pay only if the appeal wins
- One provider, one process, for landlords concentrated in a single state
- Handles both residential and commercial parcels
Where Ownwell falls short:
- No flat-fee option for landlords who want a fixed, budgetable cost per door
- The fee scales with the reduction, so a bigger win costs more
Best for: landlords with a small, single-state portfolio who want a fully hands-off process and don't need county-by-county customization.
Verdict: Hold β no reason to switch if your rentals sit in one covered state.
3. O'Connor & Associates: best for landlords fully invested in Texas
O'Connor & Associates is one of the longer-running property tax consulting firms operating in Texas, handling both residential and commercial protests before county appraisal districts. For a landlord whose entire book of business sits inside Texas county lines, that depth of local experience matters.
Where it shines: long track record with Texas appraisal districts and experience with commercial parcels, not just single-family homes.
Where it falls short: Texas-only, so one out-of-state rental means adding a second vendor and a second process.
Best for: landlords whose entire portfolio sits inside Texas and who want an established, contingency-based firm.
Verdict: Buy for all-Texas portfolios; Skip if you own anything outside the state.
4. DIY self-filing: best for one or two properties you know well
Filing your own flat-fee self-serve property tax appeal alternative β a fully DIY filing β costs nothing beyond the hours it takes to pull comps, build an evidence packet, and show up to the hearing. For a landlord with a single rental in a familiar county, that's a fair trade.
It stops making sense once you're juggling multiple deadlines in one season: Texas's May 15 cutoff, Georgia's roughly 45-day window from the notice, and New Jersey's April 1 filing date β which is January 15 in Burlington, Gloucester, and Monmouth counties.
Where DIY shines: zero cost beyond your time, and it works in any county or state you own property in.
Where DIY falls short: no professional comps analysis, no hearing representation, and a much higher chance of missing a deadline across a multi-property portfolio.
Best for: a landlord with one or two properties in a county they already understand.
Verdict: Buy for a single rental; Skip at three doors or more.

Why landlords switch from Ownwell
- The portfolio crossed a state line. A pure contingency model doesn't flex for an owner who needs a Texas protest on one property and a California appeal on another in the same year.
- They want a fixed cost. A flat fee per property, per tax year, is easier to budget across a rental portfolio than a fee that grows with the reduction.
- New Jersey rentals. New Jersey isn't a plain appeal. The County Board of Taxation tests your assessment against the Chapter 123 ratio and is required by statute to raise the assessment when the ratio falls below the common level range. Landlords want a process that screens for that risk before filing, not a generic national one.
- Maryland rentals. Maryland is state-assessed through SDAT and reassesses roughly one third of the state each year, so a landlord needs to know which cycle their property falls into before doing anything in 2026.
- Equity arguments only exist in two states. The unequal-appraisal argument β comparing your assessment to comparable assessments rather than sales β is a Texas and Georgia statute. It does not apply in California, Florida, New Jersey, or Maryland, and a service that treats every state the same misses that.
When staying with Ownwell is the right call
If you own one or two rentals in a single state Ownwell already covers, and you'd rather never think about deadlines or filing bodies again, staying put is a reasonable call. Switching vendors carries its own overhead, and a small single-state portfolio doesn't need six state processes solved at once. Revisit the decision the year you buy a door outside that state.
FAQ
What's the best Ownwell alternative for landlords with rentals in multiple states?
TaxDrop is built for that case β a licensed-consultant protest in Texas plus a flat-fee self-serve appeal packet for California, Georgia, Florida, New Jersey, and Maryland, each matched to that state's deadline and terminology.
Is TaxDrop better than Ownwell for landlords?
TaxDrop is the better fit for a multi-state portfolio or for landlords who want a flat fee instead of a percentage of savings. Ownwell is a fine fit for a small, single-state portfolio that wants a pure contingency process.
How do property tax appeal companies charge landlords?
Most charge a contingency fee tied to the reduction they win. TaxDrop's full-service Texas protest charges nothing unless it reduces your assessment, and its self-serve packet charges one flat fee per property, per tax year.
Does Ownwell work for rental properties?
Yes. Ownwell handles residential and commercial parcels, including rentals, in the states it covers. The constraint is fee structure and multi-state complexity, not property type.
What happens if a property tax appeal doesn't win a reduction?
Under a no-reduction-no-fee model you pay nothing. A flat-fee self-serve packet is paid upfront regardless of outcome, because the fee covers the packet and evidence build, not a guaranteed result.
Is a DIY property tax appeal worth it for landlords?
It's worth it for one or two properties in a county you know well. It gets hard to justify once you're tracking several deadlines across multiple counties or states in the same season.
When is the property tax protest deadline in Texas?
May 15 is the standard Texas protest deadline with your county appraisal district. Texas appeal activity peaks March through May, so start pulling comps before the notice of appraised value arrives.
Can filing a property tax appeal increase my assessment?
In New Jersey, yes. The county board decides on the Chapter 123 ratio test, and when your assessment falls below the common level range the board is required by statute to increase it.
One last thing
Maryland reassesses about one third of the state each year, which means a Maryland landlord doesn't get a live appeal window every season. Miss the cycle your property falls into and you wait roughly three years for the next one. Check which reassessment group your Maryland rental sits in before assuming you can file in 2026 β and note that Maryland's window runs December through February, the opposite end of the calendar from Texas.
