The quick read: A DSCR loan on a Salt Lake City rental is sized on the property's rent divided by the full monthly payment, not on the investor's personal income. NerdWallet's DSCR guide (updated July 17, 2026) says that payment includes principal, interest, taxes, insurance and HOA fees, and that lenders typically want a ratio of around 1.25 or higher. The Salt Lake City line that most often moves the answer is property tax. The Utah State Tax Commission says a residence that serves as someone's primary residence receives a 45% exemption from fair market value, owner or tenant, while a second residence or an unoccupied residential property is taxed at 100%. So the tax line depends on how you will use the building, not on what the seller paid. Rebuild it before you size the loan.
How does a DSCR loan work on a Salt Lake City rental property?
A DSCR loan on a Salt Lake City duplex or fourplex qualifies the purchase on the rent the units produce compared with the full monthly payment, taxes and insurance included, rather than on the investor's tax returns. NerdWallet says lenders typically want a ratio of around 1.25 or higher on a property the borrower will not live in.
NerdWallet's guide writes the formula as monthly rental income divided by the monthly loan payment. A DSCR calculator runs the same math on your numbers. NerdWallet describes the typical terms this way; each lender sets its own sheet, so treat them as a starting point:
Typical minimum DSCR (NerdWallet, updated Jul 17, 2026): around 1.25 or higher
Credit score (NerdWallet, updated Jul 17, 2026): at least 620
Down payment (NerdWallet, updated Jul 17, 2026): at least 20%
Minimum loan amount (NerdWallet, updated Jul 17, 2026): around $100,000
Reserves (NerdWallet, updated Jul 17, 2026): three to six months of mortgage payments
Prepayment (NerdWallet, updated Jul 17, 2026): most DSCR loans carry prepayment penalties
NerdWallet also says a DSCR loan can't be used to buy a fixer-upper or a primary residence. The occupancy line has a federal definition behind it. The Consumer Financial Protection Bureau's official interpretation of Regulation Z says credit to acquire, improve or maintain rental property that is not owner-occupied is deemed to be for business purposes, regardless of the number of housing units, and that if the owner expects to occupy the property for more than 14 days during the coming year, it cannot be considered non-owner-occupied. An investor who plans to live in one side of a Sugar House duplex is shopping for a different loan.
Why do Salt Lake City DSCR borrowers mostly buy existing small buildings?
Salt Lake City DSCR borrowers mostly buy existing small buildings because new multifamily supply in the metro arrives in large projects: the Census Bureau counted 89 buildings of five or more units permitted across the Salt Lake City-Murray metro in 2025, carrying 4,471 units, about 50.2 units per building (our arithmetic).
The same 2025 Census file shows how little small multifamily gets built. Across the metro, permits covered 38 two-unit buildings with 76 units and 39 buildings of three or four units with 140 units, against 3,015 single-family homes. The towers going up in the Granary District sit in a different financing world. The duplex, triplex or eight-unit walk-up an investor buys in Sugar House, Rose Park, Fairpark, Central Ninth or Liberty Wells is almost always an existing building, so its age, condition and current tax status go straight into the underwriting.
Salt Lake City-Murray metro, 5+ unit buildings permitted in 2025 (Census Bureau): 89 buildings, 4,471 units
Salt Lake City-Murray metro, 2-unit buildings permitted in 2025 (Census Bureau): 38 buildings, 76 units
Salt Lake City-Murray metro, 3-and-4-unit buildings permitted in 2025 (Census Bureau): 39 buildings, 140 units
The unit count also decides which lending box the building sits in. The interagency real estate lending guidelines that federal bank regulators publish (12 CFR Part 34, Subpart D, Appendix A, 2025 edition) list 1- to 4-family residential property that is not owner-occupied and residential property with five or more dwelling units as separate types of improved property, with an 85% supervisory loan-to-value ceiling for improved property. A fourplex sits in the first group; a fifth unit moves the building into a commercial multifamily conversation about the full operating statement.
Do not lean on rent growth to close the gap. Size the loan on the leases in place today, and treat any rent increase as upside rather than as part of the coverage test.
How does Utah's 45% residential exemption change the DSCR on a rental?
Utah's 45% residential exemption changes the DSCR because the tax line on a Salt Lake City rental can be computed on 55% of market value or on 100% of it, depending on whether a tenant lives there as a primary residence, and the difference is large enough to move a building above or below a 1.25 coverage test.
The Utah State Tax Commission's residential property page states the rule plainly. Residential properties that serve as someone's primary residence receive an exemption of 45% of fair market value. The exemption applies regardless of whether the resident is an owner or a tenant. It covers one acre of land per residence plus the associated buildings, it is limited to one primary residence per household, and the owner may need to apply with the county assessor to receive it. A second residence or an unoccupied residential property is taxed on 100% of value.
| How the unit is used | Taxable share of market value (Utah Tax Commission) | What it means for the DSCR line |
|---|---|---|
| How the unit is used Long-term lease to a tenant who lives there as a primary residence | Taxable share of market value (Utah Tax Commission) 55% (45% exemption) | What it means for the DSCR line Lowest tax line; confirm the exemption is on the parcel record |
| How the unit is used Owner's own primary residence | Taxable share of market value (Utah Tax Commission) 55% (45% exemption) | What it means for the DSCR line Not a DSCR loan; the investor occupies it |
| How the unit is used Second residence | Taxable share of market value (Utah Tax Commission) 100% | What it means for the DSCR line Full-value tax line |
| How the unit is used Unoccupied residential property | Taxable share of market value (Utah Tax Commission) 100% | What it means for the DSCR line Full-value tax line during vacancy |
| How the unit is used Nightly rental (no one's primary residence) | Taxable share of market value (Utah Tax Commission) 100% (our reading: no household uses it as a primary residence) | What it means for the DSCR line Full-value tax line, plus licensing limits |
Two practical rules follow. First, never inherit the seller's tax bill. A seller who lived in the house, or who kept tenants on long leases, may show a bill based on 55% of value; a seller whose units sat empty or ran as nightly rentals may show 100%. Your bill depends on your use, so rebuild it from your plan. Second, confirm the paperwork. The Tax Commission says the owner may need to apply with the county assessor, so ask the Salt Lake County Assessor what it requires when title transfers and lock that step into your closing checklist.
Can you use short-term rental income on a Salt Lake City DSCR loan?
You can use short-term rental income on a Salt Lake City DSCR loan only where the city will license the unit, and the city's licensing districts are mostly mixed-use, downtown and commercial zones, so most small rental buildings in residential neighborhoods should be underwritten on long-term leases instead.
The Salt Lake City Council passed Ordinance 38 of 2026 on June 16, 2026, enacting Chapter 5.13 of the city code on short-term rental business licenses, according to the notice published on the Utah Public Notice Website on July 1, 2026. The city's Finance department page sets the operating terms:
License (Salt Lake City Finance): required before advertising the property or accepting bookings
Approved districts (Salt Lake City Finance): MU2, MU3, MU5, MU6, MU8, MU11, M1, M1-A, D1, D2, D3, D4, GMU, RP, BP, A, JRF
Minimum stay (Salt Lake City Finance): two consecutive nights
Annual cap (Salt Lake City Finance): 200 rental nights per calendar year
Larger buildings (Salt Lake City Finance): more than 11 dwelling units may license up to 10% of units
The city's single-family and multifamily residential districts are not on that list. Two underwriting consequences follow. A 200-night cap limits the income a nightly rental can show, and a nightly unit is no one's primary residence, which puts it on the full-value side of the tax table above. NerdWallet notes DSCR loans can be used for short-term and vacation rentals, but in Salt Lake City the license and the zone come first.
What does the DSCR math look like on an illustrative Salt Lake City duplex?
On an illustrative $480,000 Salt Lake City duplex renting for $3,550 a month, a $360,000 loan at an assumed rate inside NerdWallet's 6% to 8% typical DSCR range produces a DSCR of about 1.26 when tenants hold Utah's 45% exemption, but about 1.19 if the tax line is computed on full value, enough to fail a 1.25 test.
Every input below is an illustrative assumption, not a quote, a market rate, an appraisal, a rent survey or a Salt Lake County tax rate. The tax rate is an assumed 0.95% of taxable value, used only to show the mechanism. Pull the parcel's actual rate from the county before you model.
| Illustrative line (our arithmetic) | Long-term tenants, 45% exemption | Full value (vacant or nightly) |
|---|---|---|
| Illustrative line (our arithmetic) Value (assumption) | Long-term tenants, 45% exemption $480,000 | Full value (vacant or nightly) $480,000 |
| Illustrative line (our arithmetic) Gross rent, two units (assumption) | Long-term tenants, 45% exemption $3,550.00 | Full value (vacant or nightly) $3,550.00 |
| Illustrative line (our arithmetic) Loan at 75% of value | Long-term tenants, 45% exemption $360,000 | Full value (vacant or nightly) $360,000 |
| Illustrative line (our arithmetic) Principal and interest, 7.25%, 30-year amortization | Long-term tenants, 45% exemption $2,455.83 | Full value (vacant or nightly) $2,455.83 |
| Illustrative line (our arithmetic) Taxable value | Long-term tenants, 45% exemption $264,000 | Full value (vacant or nightly) $480,000 |
| Illustrative line (our arithmetic) Property tax at assumed 0.95% | Long-term tenants, 45% exemption $209.00 | Full value (vacant or nightly) $380.00 |
| Illustrative line (our arithmetic) Insurance (assumption) | Long-term tenants, 45% exemption $150.00 | Full value (vacant or nightly) $150.00 |
| Illustrative line (our arithmetic) Total payment | Long-term tenants, 45% exemption $2,814.83 | Full value (vacant or nightly) $2,985.83 |
| Illustrative line (our arithmetic) DSCR | Long-term tenants, 45% exemption 1.26 | Full value (vacant or nightly) 1.19 |
| Illustrative line (our arithmetic) Loan that reaches 1.25 | Long-term tenants, 45% exemption About $363,700 | Full value (vacant or nightly) About $338,600 |
The same building, the same rent and the same loan land on opposite sides of the lender's ratio. The $171 monthly difference in tax costs about $25,000 of loan proceeds at these terms (all our arithmetic). If the seller's bill shows the exemption and your plan is long-term leases, confirm the exemption carries over after the sale. If the seller's bill shows full value and you plan long-term leases, your tax line may drop once the assessor applies the exemption, but do not size on that until it is on the record.
Which lenders finance Salt Lake City rentals on DSCR?
DSCR and non-QM investor lenders are the core option for a non-owner-occupied Salt Lake City duplex or fourplex, portfolio banks and credit unions may underwrite the borrower alongside the building, and buildings of five or more units move into commercial multifamily programs that look at the full operating statement rather than a single ratio.
DSCR and non-QM investor lenders. These lenders qualify the deal on the property's coverage. Their published minimums differ, so compare the ratio, the leverage, the minimum loan amount, the reserve requirement and the prepayment schedule in writing, side by side.
Portfolio banks and credit unions. A lender that keeps the loan sets its own coverage and pricing inside the 85% supervisory ceiling for improved property.
Five units and up. The interagency guidelines treat residential property with five or more units as its own category. Expect questions about operating expenses, vacancy and capital reserves.
Ask every lender the same three Salt Lake City questions: does it underwrite taxes from the current bill, the purchase price or its own estimate; does it give credit for Utah's 45% residential exemption on a tenant-occupied unit; and will it count any nightly rental income in a licensed district.
How do you get a Salt Lake City DSCR loan placed with the right lender?
You get a Salt Lake City DSCR loan placed by sending every lender the same complete package, with the leases, the parcel's current tax record and exemption status, the insurance quote and the target loan size, so their quotes are comparable. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors.
YieldStack's software matches the deal against a catalog of 20,000+ loan programs, a count of programs rather than of lenders. Human brokers then structure the request, negotiate for the borrower and carry the deal toward closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
What to send:
- Property address, parcel number and the current Salt Lake County tax record, including whether the residential exemption is applied
- Current leases or a rent roll for every unit, with vacancy history
- Your planned use: long-term leases, or a licensed nightly rental in an approved district
- An insurance quote or the current declarations page
- Purchase contract or payoff statement, plus any repair scope
- Target loan amount, expected hold and the prepayment penalty you can accept
The Salt Lake City market hub collects our Salt Lake City material and the Utah market hub covers the rest of the state; neither is a promise of any particular lender or term. When the package is ready, send the deal for review. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
The bottom line
A DSCR loan on a Salt Lake City rental is one division: documented rent over the full payment. Build the tax line from your own plan, because Utah taxes a tenant's primary residence on 55% of value and a vacant, second or nightly unit on 100%, then underwrite on long-term leases unless the unit sits in a district where the city will license nightly stays.
