Buying Before You Sell in Utah: The Whole Picture
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
Everything a Utah homeowner needs before making an offer on the next house: the three ways to fund it, what the property tax statute does during the overlap, and where the county limits change the structure.
Take it in this order
Most buy-before-you-sell advice starts with the loan. In Utah that is the wrong first question, because the tax consequence of the overlap is larger and less reversible than the difference between the financing options. Work in this order: what happens to your exemption, then what the county limit allows, then which structure fits the income.
One: what happens to the 45%
Utah Code 59-2-103(3) allows residential property a residential exemption equal to a 45% reduction in the value of the property. Subsection (6)(a) limits it to one primary residence per household, and (1)(a)(ii) defines household to include married individuals not legally separated who have established domiciles at separate locations within the state, which closes the two-names workaround.
The exception in (6)(b)(ii) preserves the exemption for each residential property that is the primary residence of a tenant. A vacant house on the market qualifies for nothing. A tenanted house keeps its reduction. Details on the exemption page and the tenant exception page.
Two: what your county allows
The 2026 FHFA one-unit conforming limit is $832,750 across 25 of Utah's 29 counties. Salt Lake, Utah, Davis, Weber, Washington, Cache, Tooele, Box Elder, Iron, Morgan and Juab all sit there. Summit and Wasatch counties are $1,150,000, with $1,472,250 on two units. Wayne County is $997,050 and Grand County is $839,500.
The gap between Salt Lake County and Summit County is $317,250 for houses about 25 miles apart. That single line decides whether the new purchase is conforming or jumbo, and jumbo underwriting treats a departing residence differently and asks for more reserves. See the jumbo page.
Three: which structure fits
Carry both and recast. Borrow against the departing home's equity. Or keep it and rent it. The structures page compares them properly, including what each does to the exemption.
The rental-income rules changed in September 2026
If you are considering the third route, this is current and it is stricter than older articles describe. Fannie Mae Selling Guide B3-3.8-05, dated 09/02/2026 under Announcement SEL-2026-08:
- A primary residence that will be vacated and converted to an investment property when the borrower purchases a new primary residence is eligible.
- The lender must document a current housing payment to use any rental income from the departing residence.
- Documentation is a complete appraisal including market rents, a Form 1007 rent schedule for the occupied unit, or market analysis tools with at least three comparable rentals from the same market area where possible.
- Lease agreements are not permitted for any departing residence.
- Adjusted net rental income is gross rent times 75% less that property's PITIA. Positive offsets that PITIA only. Negative is added to the debt-to-income ratio.
- Six months of reserves for the vacated property's PITIA when the borrower has less than 12 months of property management experience, in addition to reserves for multiple financed properties.
Mechanics on the Form 1007 page and the Utah-specific version on the rental conversion page.
Where in Utah you are moving matters
Zillow put the typical home value in August 2026 at $560,068 in Salt Lake City, $539,276 in Provo, $511,736 in Ogden, $526,381 in St. George and $1,151,512 in Heber. Heber rose 3.7% year over year and Ogden 2.1%. St. George fell 0.8%.
Direction matters more than level for a bridge, because reserve tiers move with how long homes take to sell. Read the move-up market page, then the metro pages for Salt Lake City, Provo and Orem, Ogden, Park City and Heber and St. George.
Two situations we get asked about constantly
Under contract but not closed and listed but not sold are different underwriting problems with different answers. They have their own pages.
Frequently asked questions
What is the first thing a Utah homeowner should check before buying the next house?
What happens to the residential exemption during the overlap. Utah Code 59-2-103(6)(a) limits the 45% reduction to one primary residence per household, so the home you are still carrying can lose it while it sits vacant. That consequence is larger and harder to undo than the difference between the financing options.
What are the 2026 conforming loan limits in Utah?
$832,750 on one unit in 25 of Utah's 29 counties, including Salt Lake, Utah, Davis, Weber, Washington, Cache and Tooele. Summit and Wasatch counties are $1,150,000 one-unit and $1,472,250 two-unit. Wayne County is $997,050 and Grand County is $839,500. FHFA 2026 county file.
Why does the Summit County loan limit matter for a move-up?
Because it is $317,250 higher than Salt Lake County's for homes roughly 25 miles apart, and it decides whether the purchase is conforming or jumbo. Jumbo underwriting handles a departing residence differently and generally asks for more reserves, which changes how the whole move is structured.
Did the rules for using rental income from a departing residence change?
Yes. Fannie Mae Selling Guide B3-3.8-05 is dated 09/02/2026 under Announcement SEL-2026-08. Lease agreements are no longer permitted for any departing residence, qualifying income is gross rent times 75% less that property's PITIA as an offset only, and six months of reserves apply when the borrower has less than 12 months of property management experience.
Does the lender need to see my current housing payment?
Yes. B3-3.8-05 states the lender must document a current housing payment in order to use any rental income from the departing residence in qualifying, and must include all documentation used to determine monthly market rents in the loan file.
