The Tenant Exception That Keeps Your Utah Exemption
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
One clause decides which Utah move-up is cheapest. It says the exemption survives on a home that is a tenant's primary residence, and it is the reason renting beats carrying here.
The clause
Utah Code 59-2-103(6)(a) limits the residential exemption to one primary residence per household. Subsection (6)(b) then lists what an owner of multiple primary residences located within the state still gets:
- (i) subject to (6)(a), the primary residence of the owner;
- (ii) each residential property that is the primary residence of a tenant; and
- (iii) subject to Subsection 59-2-103.5(4), each residential property described in Subsection 59-2-102(35)(b)(ii).
Item (ii) is the one that matters when you are leaving a house behind. The exemption follows occupancy, and the statute accepts somebody else's occupancy. A tenant who makes the home their primary residence keeps the 45% reduction attached to it.
Why it decides the structure
Line the three financing routes up against that sentence.
| Structure | State of the departing home | Exemption under 59-2-103(6) |
|---|---|---|
| Carry both payments, recast after the sale | Vacant and for sale | Nobody's primary residence, so no exemption |
| Borrow against the departing home's equity | Vacant and for sale | Same. The lien has no bearing on occupancy |
| Keep it and rent it | A tenant's primary residence | Preserved under (6)(b)(ii) |
In most states the rental conversion is the compromise you accept when the debt-to-income ratio will not stretch. In Utah it is the structure the tax statute rewards. The two things point the same way, which is unusual and worth planning around rather than discovering afterward.
What counts as a tenant's primary residence
The statutory words are narrow and they are the words a county will read. The property has to be the primary residence of a tenant. A home sitting empty with a listing on it does not qualify. Neither does a home marketed by the night. A tenant in place who lives there does.
Utah Code 59-2-103.5 governs the procedure. Under (1) a county may require an application where the property was ineligible the previous year, where an ownership interest changes, or where the board of equalization has reason to believe the property no longer qualifies. Converting your former home to a rental is precisely the kind of change that invites that question, so expect to document the tenancy to your county and ask the assessor what they want to see. This page is not tax advice and your county administers the exemption, not us.
The tension between the tax rule and the loan rule
Here is the part that catches people, and it is genuinely awkward. The lease is what proves the tenancy for your exemption. The lease is also the one document the mortgage rulebook will not look at.
Fannie Mae Selling Guide B3-3.8-05, dated 09/02/2026 under Announcement SEL-2026-08, states that lease agreements are not permitted for any departing residence. Qualifying market rent is documented by a complete appraisal that includes market rents, a Single-Family Comparable Rent Schedule on Form 1007 for the occupied unit, or market analysis tools with at least three comparable rental properties, from the same market area where possible.
So a Utah borrower converting a departing residence ends up with two parallel paper trails. One is the tenancy, for the county. The other is documented market rent, for the loan. Neither substitutes for the other. Plan for both at the same time instead of discovering the second one in underwriting. The mechanics are on the Form 1007 page.
The rest of the math
Preserving the exemption lowers the departing home's tax line, which lowers its PITIA, which matters twice. It improves the property's own cash flow, and because qualifying rental income is monthly gross rent times 75% less that property's PITIA, a smaller PITIA makes a positive result more likely. A positive result offsets that property's payment. It never adds income.
Under 12 months of property management experience, B3-3.8-05 also requires six months of reserves for the vacated home's PITIA, on top of any reserves required for multiple financed properties. A preserved exemption shrinks that reserve figure too, because reserves are measured against the payment.

Frequently asked questions
Does Utah's residential exemption survive if I rent out my old house?
Yes. Utah Code 59-2-103(6)(b)(ii) allows an owner of multiple primary residences a residential exemption for each residential property that is the primary residence of a tenant. A tenant who actually lives in the home keeps its 45% reduction in place.
Why does renting the departing home beat carrying two payments in Utah?
Because of occupancy. Utah Code 59-2-103(6)(a) limits the exemption to one primary residence per household, and a vacant house for sale is nobody's primary residence, so it loses the 45% reduction. A tenanted home qualifies under (6)(b)(ii). Carrying both payments and borrowing against equity both leave the departing home vacant.
Does a short-term rental keep the Utah residential exemption?
The statute requires the property to be the primary residence of a tenant. Nightly or short-stay letting does not establish a tenant's primary residence, so it does not meet the words of 59-2-103(6)(b)(ii). Your county assessor administers this, so confirm your specific arrangement with them.
Can I use my tenant's lease to qualify for the new mortgage?
No. Fannie Mae Selling Guide B3-3.8-05, dated 09/02/2026, states that lease agreements are not permitted for any departing residence. Market rent is documented by a complete appraisal including market rents, a Form 1007 rent schedule, or market analysis tools with at least three comparable rentals. The lease supports your county exemption, not your loan file.
How much rental income can I use from the home I am leaving?
Monthly gross rent times 75%, less that property's PITIA. If the result is positive it offsets the departing residence's payment only and never adds qualifying income. If it is negative, the amount goes into your debt-to-income ratio. That is Fannie Mae B3-3.8-05.
Will I need extra reserves to convert my Utah home to a rental?
With less than 12 months of property management experience, Fannie Mae B3-3.8-05 requires six months of reserves to cover the vacated property's PITIA, in addition to any reserves required for multiple financed properties. Keeping the residential exemption on that home lowers its PITIA, which lowers the reserve figure as well.
