If you have a solar or battery storage lease on your ground, expect the phone to ring. Some callers want to buy the land under the project. Others want to buy the rent: they will pay you a lump sum today in exchange for the lease payments over the next ten, twenty or thirty years.
That can be a smart move, especially for an older landowner who would rather have the money now than wait on a check that arrives once a year until 2050. But the price, the structure and the tax treatment are all negotiable, and the buyer’s first draft is written for the buyer. Here is how these deals work and where the money gets left on the table.
What a “rent strip” actually is
A rent strip sale is the sale of the right to collect lease rent for a set period. You keep the land. When the strip ends, the rent comes back to you or your heirs. Anything outside the strip — extension-term rent, a revenue share, the land itself — stays with you unless the documents say otherwise.
None of this is new. Cell tower landlords have been selling their lease income for decades, either through a permanent easement or a long term-limited assignment. In the United Kingdom, investors now buy renewable ground-lease income as a long-term asset class. A solar or battery storage strip is the same idea applied to a shorter and riskier tenancy.
The deal can be built several ways, from lightest to heaviest:
- Bare assignment of rents. You stay the landlord and assign only the right to receive rent for a number of years. Simplest paperwork, and the weakest position on taxes.
- Assignment of the lessor’s interest plus an easement. The buyer steps into your shoes as landlord for the strip period and holds a recorded interest in the property. Institutional buyers prefer this.
- Partial strip. Sell only the first ten years, or half the rent for the whole term. Useful when you need some cash but want continuing income.
- Developer prepayment. Before you shop the lease to investors, ask your tenant whether it will prepay rent. Developers sometimes have cheaper money than investors and may pay more. Even a “no” gives you a benchmark.
Selling the land outright to the developer, or to an aggregator who leases it back, is a different transaction with different consequences. It belongs in the same conversation, but it is not a rent strip.
Why the calls are coming now
Illinois is building battery storage on a deadline. State law directs the Illinois Power Agency to run procurements for 3,000 megawatts of energy storage for projects committed to reach commercial operation by December 31, 2030, subject to extensions (20 ILCS 3855/1-75(d-20)). We walked through what that program requires in Illinois Is Buying 3,000 Megawatts of Storage.
The rents are real. In the Illinois Society of Professional Farm Managers and Rural Appraisers’ mid-year 2026 survey, a third of respondents reported battery storage inquiries or option agreements in the first half of the year. Of the seven guaranteed battery storage base rents respondents knew of, four were $1,500 to $4,999 per acre, two were $5,000 to $9,999, and one was $10,000 or more. New solar and wind leases mostly ran $1,000 to $1,999 per acre. Most respondents also reported that an active energy lease adds a premium when the farm sells.
Developers are noticing that land is worth owning, too. In September 2026, Energy Vault announced it had bought the land under its 125 MW / 1 GWh Stoney Creek battery project in Australia rather than continue leasing it. Specialized land aggregators and online marketplaces are doing the same thing in the U.S.
How the buyer prices your rent
Buyers price a rent strip by discounting each future payment back to today at their required rate of return. That rate is not the inflation rate. It is a base rate plus a premium for everything that could go wrong: the tenant’s credit, whether the tenant can walk away, whether the project is built yet, and how the technology ages.
Here is a hypothetical: five acres at $5,000 per acre, or $25,000 a year, with a 2% annual escalator and 25 years left on the lease.
| Buyer’s discount rate | Lump sum today | Multiple of first-year rent |
|---|---|---|
| 7% | about $349,000 | 14.0x |
| 8% | about $317,000 | 12.7x |
| 10% | about $265,000 | 10.6x |
A three-point change in the discount rate moves the price by more than $80,000. That one assumption is where most of the negotiation happens.
Watch out for “cap rate” shortcuts. A cap rate assumes the income lasts forever. A battery lease does not, and battery equipment has a limited useful life. Applying a perpetual 6% cap rate to the same lease produces about $417,000 — roughly $100,000 more than the lease is worth at 8%. If a buyer’s math looks generous, check whether it is quietly assuming a lease that never ends, and what it plans to claw back later.
Cell tower buyouts are a useful reference point, but they are usually permanent or very long interests backed by national carriers. A battery storage lease with a single-project LLC as the tenant should price lower than that, not higher.
Sell the front years, keep the back years
This is the point most landowners miss. Because distant payments are discounted the most, the back half of a lease adds surprisingly little to the price.
| Years sold | Rent you give up | Cash at 7% | Cash at 8% | Cash at 10% |
|---|---|---|---|---|
| 10 years | $274,000 | $190,000 | $181,000 | $166,000 |
| 15 years | $432,000 | $256,000 | $240,000 | $212,000 |
| 20 years | $607,000 | $308,000 | $284,000 | $243,000 |
| 25 years | $801,000 | $349,000 | $317,000 | $265,000 |
At 8%, stretching the sale from 15 years to 25 years puts about $77,000 more in your pocket — and gives up about $368,000 of later rent. For many families, a shorter strip delivers most of the cash and leaves the back-end rent and the land for the next generation.
A quick way to test an offer: divide the first-year rent by the price. That is the buyer’s going-in yield. Then work out what discount rate makes the stream of payments equal the offer. If a buyer is pricing an operating project with a strong parent guaranty at 10% or more, the offer is probably light.
What moves the price up or down
- Project stage. Option payments on a project that has not been built are worth far less than rent from an operating facility. Many buyers will not pay for rent that has not started.
- Termination rights. The biggest value driver. If the tenant can walk away on notice, the buyer prices that risk heavily. This is also the clause most worth tightening before you sign the lease in the first place.
- Who stands behind the rent. A single-purpose project LLC is worth less than a parent guaranty or an investment-grade owner.
- Extensions and revenue share. Some buyers include them at a steeper discount; others ignore them. Make the buyer say exactly what it is buying, and consider keeping both.
- Battery-specific terms. Decommissioning security, fire and contamination indemnities, and the tenant’s rights to augment or repower all affect how a buyer sees the risk.
The capital gains pitch: be careful
Buyers and marketers often tell landowners the lump sum will be taxed as long-term capital gain. Sometimes that is right. Often it is not, and the difference can be large.
The problem is a line of federal tax law that is more than eighty years old. In Hort v. Commissioner, 313 U.S. 28, 31 (1941), a landlord took a lump sum to cancel a lease, and the Supreme Court held the payment was “merely a substitute for the rent” — ordinary income, not capital. In Commissioner v. P.G. Lake, Inc., 356 U.S. 260, 265 (1958), the Court went further: a company that sold a carved-out right to future oil payments for a lump sum had ordinary income, because the payment was “essentially a substitute” for income it would otherwise receive later. The Court reached that result even though it treated the oil payments as interests in land.
That last point matters. Calling the thing you sell a “real property interest” does not by itself turn rent into capital gain.
The other side of the line is a sale of your whole interest. In McAllister v. Commissioner, 157 F.2d 235, 236 (2d Cir. 1946), a life beneficiary who gave up her entire life interest in a trust was treated as selling a capital asset, and the court expressly distinguished Hort. The more a transaction looks like a sale of a complete property interest, and the less it looks like selling a slice of the income while keeping everything else, the stronger the capital gain argument.
Three practical consequences:
- Structure matters, but it is not magic. An assignment of the lessor’s interest with a recorded easement is a better starting point than a bare assignment of rents. An easement that exactly matches the rent period can still be attacked as a rent sale in disguise.
- Watch the bunching. If the proceeds are ordinary income, twenty years of rent can land in one high-bracket tax year. Installment payments may soften that.
- Like-kind exchanges need the right kind of interest. Treasury regulations treat a leasehold with 30 years or more to run as like-kind to fee real estate (Treas. Reg. § 1.1031(a)-1(c)). A short rent assignment does not fit that mold.
Do not assume capital gain treatment. Have the deal structured before you sign a letter of intent, not after.
What should be in the documents
Start with the lease itself: what it says about assignment and consent, termination, setoff and abatement, revenue share, decommissioning security and extensions. Then make sure the sale documents cover:
- No clawback. If the tenant terminates or the project fails, you should not owe the buyer a refund. This is the single most important term.
- Limited, capped indemnity. Your responsibility should be limited to your own conduct — interfering with the tenant, placing new liens on the property — and capped.
- Tenant estoppel and direction letter. The tenant confirms the rent, the term and that there are no defaults or prepaid rent, and is directed to pay the buyer.
- Your mortgage lender. If there is a mortgage, the lender may already hold an assignment of rents and may need to consent or require a paydown.
- Your obligations during the strip. Who pays property taxes, who controls lease amendments and consents, and who receives notices.
- The end of the strip. How the landlord’s rights come back to you, what happens to decommissioning security, and whether the buyer can extend or renegotiate near the end.
Everything gets recorded with the county recorder and will show up on title when you sell or refinance.
Older landowners and the estate plan
For many families, the real question is not “what is the rent worth?” but “who should get it?” A strip sale can fund retirement, long-term care, debt payoff or gifts to children without selling the farm. But it should fit the plan, not drive it.
- Stepped-up basis. Property acquired from a decedent generally takes a basis equal to its fair market value at death (26 U.S.C. § 1014). Selling the land or a permanent easement during life triggers gain your heirs might otherwise avoid. A shorter rent strip that leaves the land and the reversion in place keeps that option open.
- Long-term care. A lump sum is an asset. If Medicaid planning is in the picture, coordinate before the money arrives.
- Trust-owned land. If the farm is in a trust, the trustee signs, and the proceeds and the reversion should land where the trust says they should. See our farm succession and estate planning pages.
- Family. If capacity could ever be questioned, document the decision carefully and consider keeping the next generation informed.
The bottom line
A solar or battery storage lease is an asset with a market value. You can hold it, sell part of it, or sell all of it. The right answer depends on the lease terms, the buyer’s pricing, the tax structure and your family’s plans — and the buyer’s first offer reflects none of those things in your favor.
If you have an existing lease, a buyout offer, or a developer asking to buy the land, have the lease and the offer reviewed before you respond. See our wind, solar and battery lease practice.
