GRATs, IDGTs, and family LPs — real estate funding appraisals for Utah estate planners
Most published GRAT guidance assumes the funding asset is a public stock. Real estate is different — the valuation is subjective at the inception date, the asset doesn't compound the way a stock ticker does, and the qualified-appraisal piece carries more weight because the IRS has more room to challenge the value. Here is what the appraisal side of a Utah real-estate GRAT, IDGT, or family LP actually looks like.
A Park City attorney calls about a client who wants to fund a five-year GRAT with a Deer Valley spec home under construction. A St. George CPA needs a defensible value for an IDGT installment-sale promissory note on a four-property rental portfolio. A Salt Lake County family office is restructuring a family LP that holds three primary-residence-class homes and a Heber cabin, with annual lifetime-exemption gifting of fractional limited-partner interests to the next generation.
This is the work that gets done in the last six months before the federal estate-tax exemption sunset on January 1, 2026 — when the per-individual federal exemption drops from $13.99 million to approximately $7 million unless Congress intervenes. The planning urgency is real. The appraisal piece is the part that most attorneys and advisors describe to the client as "we'll just need a number" without knowing the half-dozen ways the IRS will examine it.
Below is what each of the three primary structures requires from a qualified appraiser — GRATs, IDGTs, and family LPs — plus the Utah-specific wrinkle and a brief note on the appraisal-supported discount math. Nothing here is legal or tax advice. That belongs to the planner and the CPA. This is the appraiser's piece of the file.
Quick GRAT primer — and why real estate is sometimes the wrong asset
A Grantor Retained Annuity Trust (GRAT) is an irrevocable trust into which a grantor transfers an appreciating asset, retains an annuity payment back from the trust for a fixed term of years (typically two to ten), and passes whatever remains in the trust at term-end to the beneficiaries free of additional gift tax. The classic case is a "zeroed-out GRAT": the actuarial value of the retained annuity equals the value of the contributed asset, so the gift-tax cost of funding the GRAT is effectively zero. Anything the asset earns above the IRS Section 7520 hurdle rate over the term passes to beneficiaries tax-free.
Public stock works beautifully in a GRAT. A volatile stock can spike, the annuity gets paid in shares, and the residual value can be enormous. Real estate is more complicated. The annual annuity payment — usually a five-to-twenty percent payback of the original contribution — needs to come from somewhere, and an illiquid cabin doesn't generate cash. The asset doesn't trade, so its mid-term value is appraisal-dependent rather than market-quoted. And the qualified-appraisal piece carries more weight because there's no ticker to anchor the value to.
Real estate works in a GRAT when one of three conditions holds: the property is income-producing (a rental, a commercial-style property classified as residential) so the annuity can be paid from rents; the grantor can fund the annuity from outside the trust without a deemed gift; or the asset has clear, near-term appreciation expected (a property under contract, a pre-development parcel) so the GRAT can be structured as a short-term play.
The appraisal side: a qualified IRC § 2702-compliant valuation at funding, with the effective date matching the funding date. Standard USPAP report. No discounts at funding (the GRAT receives the whole-property value, not a fractional interest). Annual valuations may be needed if annuity payments are in kind. A second appraisal at term-end if the residual transfer requires substantiation.
Real estate in a GRAT is workable. It is not the default.
The IRC § 2702 funding-valuation problem
Section 2702 is the rule that makes the GRAT possible — and also the rule that controls how carefully the funding appraisal has to be written.
The statute, in shorthand: when a grantor transfers property to a trust in which the grantor retains an interest, the retained interest is valued at zero for gift-tax purposes unless the retained interest is a "qualified interest" under § 2702(b). A qualified interest must be either a fixed-dollar annuity or a fixed-percentage unitrust paid at least annually. Get the structure right and the retained interest is valued at its actuarial present value, computed using the IRS Section 7520 rate in effect for the month of funding. Get it wrong and the retained interest is zero — meaning the entire contributed value is treated as a gift.
The math: the funding-date appraised value times the actuarial factor for the annuity term and rate equals the value of the retained annuity. Whole-property value minus retained-annuity value equals the gift portion. A zeroed-out GRAT structures the annuity to equal the contribution, leaving the gift at zero.
The appraisal side of this: any error in the funding valuation cascades into the gift-tax computation. Overvalue the funding asset and the gift portion is larger than it needs to be. Undervalue and the IRS has grounds to challenge — and if the challenge succeeds, the grantor owes gift tax on the difference plus penalties. The appraisal has to be conservative-but-defensible, with comparable sales clearly anchored, the highest-and-best-use analysis explicit, and the certifications signed by an appraiser whose credentials clearly meet the qualified-appraiser test under Treas. Reg. § 1.170A-17.
The funding number is the entire game. Every subsequent calculation flows from it.
Fractional / undivided-interest discounts for FLP-held real estate
Family limited partnerships (FLPs) holding real estate are where the most meaningful valuation discounts live. The structure: a parent family member sets up an FLP, contributes real estate (a cabin, a vacation rental, sometimes multiple properties), retains a 1-2% general-partner interest with management control, and over a period of years gifts limited-partner interests to children and grandchildren using the annual exclusion and lifetime exemption.
The limited-partner interests support real, defensible discounts beyond the underlying property value:
- Lack of marketability discount (LOM). The LP interest has no public market. A buyer would have to negotiate with the GP, evaluate the partnership documents, accept a long hold without redemption rights, and price the illiquidity. The recognized discount range for LP interests in real-estate-holding FLPs is roughly 20% to 35%.
- Lack of control discount (LOC). The limited partner cannot force a sale, distribute partnership assets, replace the GP, or unilaterally manage the property. The recognized discount range is 10% to 25%.
Combined discounts of 25% to 40% are defensible for LP interests in real-estate-holding FLPs, but the discount must be supported with reasoned analysis. Tax Court cases — Estate of Forbes, Astleford v. Commissioner, Estate of Strangi, and the more recent Estate of Grieve — define the framework. The appraiser builds the discount narrative from the actual partnership operating documents (the restrictions, the buyout provisions, the GP control rights), studies of comparable LP-interest sales where available, and reasoned application of the academic literature on private-company discounts.
This is where amateur appraisal work gets caught. A flat "20% blended discount" with no support is the kind of report the IRS audits and the Tax Court overturns. A real discount narrative — fifteen pages of partnership analysis, sale-data support, and case-law application — is what survives challenge. Be specific with whoever writes the appraisal: ask whether they have done FLP-discount work before and ask to see a redacted prior report.
The discount, supported, is real money. A 35% combined discount on a $4 million Park City rental portfolio held in FLP form means $1.4 million of additional lifetime-exemption capacity over a multi-year gifting program.
IDGT installment sales — coordinating the appraisal with the promissory note
An Intentionally Defective Grantor Trust (IDGT) is an irrevocable trust drafted so it is treated as a grantor trust for income-tax purposes (the grantor pays the trust's income tax, effectively making additional tax-free gifts) but not for estate-tax purposes (assets pass to beneficiaries outside the grantor's taxable estate). The classic real-estate move is an installment sale to the IDGT: the grantor sells appreciating real estate to the trust in exchange for a long-term promissory note bearing the IRS Applicable Federal Rate (AFR).
The appraisal piece is critical because the IRS examines two values simultaneously: the value of the real estate sold to the trust, and the value of the promissory note received in return. If the real estate is overvalued or the note is undervalued (insufficient AFR, balloon structure with no real expectation of repayment), the IRS can argue the difference constitutes a taxable gift.
The qualified appraisal at the date of sale anchors both sides. Sale price equals appraised value. Promissory-note face value equals appraised value. Note interest rate equals or exceeds the AFR for the month of sale. The grantor pays the note's interest in cash from outside the trust; the trust's appreciating real estate compounds inside without the grantor's estate growing.
What the appraiser delivers: a qualified appraisal of the real estate as of the sale date, USPAP-compliant, with comparable sales and the standard valuation approaches. For multi-property portfolios, a portfolio approach with property-by-property values rolled to a portfolio total. Annual valuations may be needed if the planner wants to demonstrate the trust's growth above the AFR each year.
The IDGT installment sale done well moves more value out of a Utah taxable estate than any other single transaction. Done badly, it invites a deficiency notice years after the planner thought the work was finished.
Utah has no state estate tax — but the federal exposure still drives the appraisal work
Utah eliminated its state estate tax after the federal credit changes following the Economic Growth and Tax Relief Reconciliation Act of 2001. Today there is no separate Utah inheritance or estate tax, and Utah does not have a state-level gift tax. Compared to states like Washington, Oregon, or Massachusetts with active state estate taxes at much lower thresholds, Utah HNW families have one less layer of planning to manage.
What this means in practice: the planning math is driven entirely by federal exposure. The federal estate-tax exemption is $13.99 million per individual in 2025, with the spousal portability election allowing a married couple to effectively shield up to $27.98 million. On January 1, 2026, the federal exemption is scheduled to sunset to approximately $7 million per individual (the pre-Tax Cuts and Jobs Act level, adjusted for inflation) unless Congress acts. That sunset is driving a surge in GRAT, IDGT, and family-LP activity through 2025 as Utah HNW families try to lock in the higher exemption before it disappears.
The appraisal market reflects this. Park City and Deer Valley properties — the $5M-$15M residential range — are the primary targets, with Heber Valley estates and East-bench Salt Lake homes a secondary cluster. The work pace through the back half of 2025 and into 2026 will be aggressive; appraiser bandwidth in Summit County and Wasatch County in particular is going to be the binding constraint, not legal capacity.
