RV Park Property Tax Reassessment: What Happens to Your Tax Bill After You Buy
The seller's T-12 shows $9,000 a year in property taxes. You buy the park, and eighteen months later the county mails you a bill for $19,000. Nothing was hidden from you. You simply underwrote the seller's tax bill instead of your own.
Property tax is one of the largest operating expenses at an RV park, and it is the one line item that your purchase can change overnight. This guide explains how reassessment works, how it differs by state, and how to build it into your numbers before you sign.
Why a Sale Can Raise Your Taxes
Counties tax property based on an assessed value. When a long-time owner holds a park for 15 years, the assessed value often lags far behind what the park would sell for today. A sale produces a fresh data point: the price you paid. Many assessors use it as evidence of market value and adjust the assessment toward it, either immediately or at the next reappraisal cycle.
Because RV parks are valued on income, the effect is larger than on a house. A park bought at a 7-8% cap rate is priced off its NOI, and a higher assessment cuts directly into that NOI. For the full valuation mechanics, see how to value an RV park.
A Simple Example
| Item | Seller's Bill | After Reassessment |
|---|---|---|
| Assessed value | $700,000 | $1,500,000 |
| Effective tax rate (illustrative) | 1.2% | 1.2% |
| Annual property tax | $8,400 | $18,000 |
| NOI impact | -$9,600 per year | |
| Value impact at a 7.5% cap rate | about $128,000 less value | |
The numbers are illustrative, but the logic is real. Every $1 of added annual tax costs you roughly $13 of value at a 7.5% cap rate. That is why the tax line deserves its own row in your model, not a copy of the seller's figure. Our guide to RV park underwriting covers how to build the rest of the pro forma.
How Reassessment Differs by State
Rules vary widely, and they change. Treat the following as orientation, then confirm with the county assessor or a local tax attorney before relying on it.
- California: Under Proposition 13, a change in ownership generally resets the assessed value to the purchase price, with annual increases capped at 2% after that. Transfers of a controlling interest in an entity can also trigger reassessment. See the California RV park listings for market context.
- Florida: Non-homestead property has an annual cap on assessment increases, but the cap resets after a change of ownership or control. New buyers often see a jump the following year.
- Texas: There is no state income tax, and appraisal districts reappraise on a regular cycle. Texas does not require sale prices to be disclosed publicly, so the county may not know what you paid. Appraisal districts still estimate market value and can raise it every year.
- Other states: Some reassess annually, some every few years, and some only on sale. Ask the assessor three questions: when is the next reappraisal, does a sale trigger one, and what is the current mill rate or effective rate?
How to Underwrite It
- Pull the current tax bill and assessed value. The county assessor's website usually has both, free.
- Find the effective rate. Divide the annual tax bill by the assessed value. Include special assessments and district levies, which can add meaningfully in some counties.
- Model the post-sale assessment. Use your purchase price, or a realistic fraction of it if the assessor typically values only the real property and excludes business value. Multiply by the effective rate.
- Run the deal on the higher number. If the deal only works at the seller's tax figure, it does not work.
- Check the escrow. Lenders often require a tax impound, which raises your cash at closing. See RV park closing costs for the full list.
Taxes sit alongside insurance, utilities, payroll, and repairs in the expense stack. Our RV park operating expenses breakdown shows typical ranges, and hidden costs of RV park ownership covers the surprises that most often hit first-time buyers.
Ways to Reduce the Hit
- Allocate the purchase price carefully. A portion of the price may belong to personal property, equipment, or goodwill rather than real property. A reasonable allocation, documented with your CPA and attorney, can affect both depreciation and what the county sees. It must be defensible, not invented.
- Appeal. Most counties give you a limited window, often 30 to 90 days after the notice, to contest the value. Bring the T-12, a rent roll, and comparable sales. Because parks are income-valued, an income-approach argument can be persuasive.
- Negotiate it into the price. If reassessment will cost you $10,000 a year, that is a documented NOI reduction. Use it as leverage. See how to negotiate an RV park purchase.
- Ask about special classifications. Some jurisdictions offer agricultural, recreational, or economic development treatment. Eligibility is narrow and local, so verify before counting on it.
- Review the tax strategy as a whole. Depreciation can offset part of the cash cost. See RV park tax benefits and depreciation.
Add It to Your Due Diligence
Put property tax on the checklist next to title, survey, and environmental. Ask the seller for three years of tax bills, request a copy of any pending appeal, and call the assessor yourself. The RV park due diligence checklist is a good place to track it.
The Bottom Line
A purchase can reset your property tax basis, and the seller's tax bill is a poor predictor of yours. Find the effective rate, model the reassessed value, run the deal on that number, and know your appeal window before closing. Doing that math upfront is cheap. Discovering it in year two is not.
