The quick read: A DSCR loan on a Fort Collins rental is sized on the property's rent divided by its full monthly payment, not on the investor's personal income, and NerdWallet's DSCR guide (updated Jul 17, 2026) says lenders generally want a ratio of around 1.25 or higher. The Fort Collins rule that changes the math is local: the City of Fort Collins' short-term rental rules say an owner of a building with three or more units cannot rent a short-term rental in it, regardless of zone. So a DSCR on a triplex, a fourplex or a 5+ unit building in Midtown or Old Town has to be built on long-term lease income alone, with no nightly-rental upside. Campus West needs its own math, because by-the-bed leases and summer gaps break a standard twelve-month rent assumption.

How does a DSCR loan work on a Fort Collins rental property?
A DSCR loan on a Fort Collins rental qualifies the property rather than the borrower's income: the lender divides monthly rent by the full monthly payment, including taxes, insurance and any association dues, and the loan can proceed if the ratio clears that lender's minimum. Credit, reserves and leverage still matter, and each lender sets its own thresholds.
NerdWallet's DSCR guide (updated Jul 17, 2026) defines the calculation as a property's monthly rental income, or projected income, divided by the loan payment. It lists the usual requirements as a DSCR of around 1.25 or higher verified through an appraisal, a credit score of at least 620 and a down payment of at least 20%, and it says most DSCR loans carry prepayment penalties and cannot be used to buy a fixer-upper or a primary residence. Treat those as one consumer guide's typical figures, not a market rule, and test your own numbers in the DSCR calculator.
The business-purpose line matters in a college town where parents buy for students. 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 an owner who expects to occupy the property for more than 14 days in the coming year cannot treat it as non-owner-occupied. A house a family member lives in rent-free is not a rental to a DSCR lender.
Why can't a Fort Collins DSCR on a three-plus-unit building count short-term rental income?
A Fort Collins DSCR on a building of three or more units cannot count short-term rental income because the City of Fort Collins says an owner of a building with three or more units cannot rent a short-term rental there regardless of zone, so the only rent a lender can underwrite is long-term lease income.
The city's short-term rental page spells out the rest of the structure. Apartment or condo buildings with three or more dwelling units are classed as multi-family R-2 buildings, and an owner who wants short-term rentals in one has to take the whole building through a change of occupancy to the R-1 building code. An accessory dwelling unit may not be used as a short-term rental. Licenses do not transfer on a sale; the new owner has to apply in their own name after closing. Where short-term rentals are allowed, the city's map separates areas that allow only primary short-term rentals from areas that allow both primary and non-primary ones, and a primary short-term rental requires proof that the owner lives at the property for most of the year.
Three consequences for a DSCR borrower follow:
- On a triplex, fourplex or larger building, build the rent roll from twelve-month leases only. A seller's pro forma that mixes in nightly income is not underwritable.
- On a single-family home or duplex, short-term rental income depends on the property's zone and on the buyer's own license, because the seller's license does not carry over. Ask lenders whether they will count it at all; see our guide to DSCR loans on short-term rentals.
- An ADU on the lot is long-term rent or nothing.
What does Fort Collins' building stock mean for DSCR financing?
Fort Collins' building stock means most DSCR files are single-family homes and small buildings, while new apartment supply arrives in mid-size projects: the Census Bureau's 2025 permit file shows 985 single-family homes and 74 buildings of five or more units with 1,367 units across the Fort Collins metro, about 18.5 units per building.
The same 2025 metro file lists 5 two-unit buildings with 10 units and 19 three- and four-unit buildings with 74 units. The Census place file for the City of Fort Collins shows 296 single-family homes, 3 two-unit buildings with 6 units, 14 three- and four-unit buildings with 54 units, and 48 buildings of five or more units with 957 units, about 19.9 units each. These are permit authorizations, not completions.
Read by neighborhood, the pattern is familiar. Midtown and the South College corridor carry most of the garden-style stock, Old Town carries older small multifamily, and Campus West carries single-family homes and small buildings leased to students. Every one of those triplexes and larger buildings sits under the three-unit short-term rental bar, and new permits add to the long-term rental supply a lender's appraiser will compare against.
5+ unit buildings permitted, Fort Collins metro, 2025 (Census BPS): 74 Units in those buildings (Census BPS, 2025): 1,367 Average units per 5+ building (our arithmetic): about 18.5
How should a DSCR be underwritten on a Campus West student rental?
A DSCR on a Campus West student rental should be underwritten on the rent the leases actually collect over twelve months, not on a by-the-bed monthly figure, because summer gaps and ten-month leases lower average monthly rent while the mortgage payment stays the same every month.
Colorado State University reports that its Fort Collins enrollment reached an all-time high of 34,412 in fall 2025, so demand near campus is real. The underwriting problem is timing, not demand. A lender comparing rent to the payment needs a monthly figure that holds all year, and a house leased by the bedroom on school-year terms does not produce one.
Illustrative example (our arithmetic, not a quote): a four-bedroom Campus West house leases each bedroom at $800, so in-season rent is $3,200 a month. The full monthly payment, including taxes and insurance, is assumed at $2,300.
- On the in-season figure, $3,200 divided by $2,300 gives a DSCR of about 1.39.
- If the leases run ten months and the house sits empty for two, annual rent is $32,000, or an average of about $2,667 a month, and the DSCR is about 1.16.
- If the appraiser uses a whole-house market rent near HUD's FY2026 four-bedroom Fair Market Rent for the Fort Collins-Loveland MSA, $2,540, the DSCR is about 1.10.
Same house, three answers. Ask each lender which rent it will count: in-place leases annualized, the appraiser's whole-unit rent schedule, or the lower of the two. Twelve-month leases with staggered start dates and parental guaranties make the file far easier to underwrite.
What published figures go into a Fort Collins DSCR quote?
A Fort Collins DSCR quote rests on a small set of published figures, each with its own source and date: lender-side guidelines from DSCR and agency term sheets, HUD's benchmark rents for checking a rent roll, and the city's short-term rental rule that decides which income counts at all.

HUD's schedule also shows how little some benchmarks moved. From FY2025 to FY2026 the Fort Collins two-bedroom FMR rose from $1,695 to $1,732, about 2.2%, and the three-bedroom from $2,375 to $2,385, about 0.4%. Do not lean on rent growth to rescue a thin ratio. Freddie Mac's term sheet adds the guardrails for a 5 to 50 unit building: loans of generally $2 million to $10 million, a 75% maximum loan-to-value on five- to under-seven-year terms and 80% on seven-year and longer terms, and non-recourse terms except for standard carve-outs.

The bottom line
A DSCR loan on a Fort Collins rental is rent over the full payment, and the city decides which rent counts. Buildings of three or more units cannot run short-term rentals, so size them on long-term leases. Underwrite Campus West on twelve months of collected rent, not a by-the-bed headline, and expect only modest rent growth.
