Qualifying in Utah While You Still Own the Old House
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
The question is really about one number: whether the payment on the house you are leaving stays in your debt-to-income ratio. Here is what moves it and what does not.
Start from the default
Underwriting assumes you owe both payments. Your current mortgage principal and interest, its taxes and insurance, any HOA dues, plus the same on the home you are buying. Both sit in the ratio until a documented rule takes one out.
That is not pessimism, it is how the guideline is written, and it is why the first useful conversation is about the size of the departing home's PITIA rather than about the new purchase.
The tax line inside that PITIA
In Utah the taxes inside that payment are not fixed. Utah Code 59-2-103(3) reduces residential taxable value by 45%, and (6)(a) allows that on one primary residence per household. A departing home left vacant does not hold the exemption; a departing home that is a tenant's primary residence does, under (6)(b)(ii).
So the structure you choose changes the PITIA that underwriting is testing. That is unusual and it is specific to Utah's statute. See the exemption page.
The rental offset, precisely
Fannie Mae B3-3.8-05, dated 09/02/2026, allows a departing primary residence being converted to an investment property to produce qualifying rental income, with conditions:
- The lender must document a current housing payment first.
- Market rent comes from a complete appraisal with market rents, a Form 1007, or market tools with at least three comparable rentals. Leases are not permitted.
- Adjusted net rental income is gross rent times 75% less that property's PITIA.
- Positive offsets that PITIA only. Negative is added to the ratio.
Read that last pair carefully, because it sets a ceiling on how much this helps. The best available outcome is neutral: the departing home stops counting. There is no version where the old house makes you stronger.
Using the equity instead
If the ratio will not carry both payments, the other lever is the down payment. A larger down payment on the new home lowers the new payment, and in Utah you can reach the departing home's equity to fund it.
That matters because it is not true everywhere. Texas caps all homestead liens at 80% combined loan-to-value under Article XVI Section 50(a)(6) of its constitution and prohibits a subordinate home equity line, which closes the route. Utah's homestead protection under 78B-5-503 is a creditor exemption over equity and does not restrict voluntary liens, so the limit is the investor guideline.
Reserves as the pressure valve
Where the ratio is tight, reserves are often what gets a file done. Under B3-3.8-05, six months of reserves on the vacated property's PITIA are required when the borrower has less than 12 months of property management experience, and that sits on top of reserves required for multiple financed properties.
Bridge structures also tier reserves against how long homes are taking to sell locally, which is why the same file looks different in Heber than in St. George. See the market page.
The ceiling nobody checks first
None of this matters if the purchase price is above what the county allows as conforming. Utah's 2026 one-unit limit is $832,750 in 25 of 29 counties and $1,150,000 in Summit and Wasatch. A Heber purchase at the typical value of $1,151,512 is already over the line. Check this before you run ratios: the jumbo page.
Two common situations have their own answers: under contract but not closed and listed but not sold. The structures sit on the structures page.
Frequently asked questions
Do both mortgage payments count when I buy before selling in Utah?
Yes, by default. Underwriting includes the full PITIA on the departing residence and on the new home until a documented rule removes one. The main rule that removes it is the departing-residence rental offset under Fannie Mae B3-3.8-05.
Can rental income from my old Utah home increase my purchase price?
No. Under B3-3.8-05 a positive adjusted net rental income may offset the departing residence's PITIA only. It never adds qualifying income. The best outcome is that the old payment stops counting against your ratio.
Can I borrow against my Utah home to make the down payment on the next one?
Yes. Utah places no constitutional cap on homestead liens. Utah Code 78B-5-503 protects a dollar amount of equity from creditors and does not restrict voluntary liens, so a closed-end second or an equity line is available subject to investor guidelines. Texas, by contrast, caps homestead liens at 80% CLTV and bars a subordinate equity line.
How does Utah's residential exemption affect whether I qualify?
It changes the payment being tested. Taxes are part of PITIA, and Utah Code 59-2-103(3) reduces residential taxable value by 45%. Because the exemption is limited to one primary residence per household under (6)(a), whether the departing home keeps it depends on which structure you choose, which in turn changes the PITIA in your ratio.
What reserves are required to buy before selling in Utah?
For a rental conversion, six months of reserves on the vacated property's PITIA when you have less than 12 months of property management experience, in addition to reserves for multiple financed properties. Bridge structures also tier reserves against local marketing time.
