Can You Use a DSCR Loan on a Boulder Rental Property or Student Rental?

The quick read: Yes, you can use a DSCR loan on a Boulder rental property or a student rental near the University of Colorado, but the ratio has to rest on long-term rent. The City of Boulder licenses short-term rentals only at the owner's principal residence, held by a natural person, trust or nonprofit, with an annual affidavit, and a short-term license is no longer valid once the property is sold. So nightly income cannot carry an investor-owned house on University Hill, in Gunbarrel or in Table Mesa. Colorado's HB24-1007, effective July 1, 2024, also changed what a by-the-bed rent roll can count: local governments can no longer cap occupancy by familial relationship, and Boulder now enforces occupancy through the International Property Maintenance Code, which requires each bedroom to be at least 70 square feet with at least 50 square feet per occupant. NerdWallet's DSCR guide (updated Jul 17, 2026) says lenders typically want a ratio of around 1.25 or higher, verified through an appraisal.

Can you use a DSCR loan on a Boulder rental property?

Yes, you can use a DSCR loan on a Boulder rental property or student rental, as long as the ratio is built on long-term rent from licensed 30-day-plus leases, because the city's short-term rental license is tied to the owner's principal residence and cannot carry an investor-owned property's coverage ratio.

A DSCR loan qualifies the property on its rent compared with the full monthly payment, not on the investor's personal income. NerdWallet's DSCR guide describes the typical terms below. Each lender sets its own sheet, so treat these as starting points rather than a Boulder rule:

DSCR formula (NerdWallet, updated Jul 17, 2026): monthly rental income divided by the loan payment, which includes principal, interest, taxes, insurance and homeowners association fees
Typical minimum DSCR (NerdWallet, updated Jul 17, 2026): around 1.25 or higher, verified through a property appraisal
Credit score (NerdWallet, updated Jul 17, 2026): at least 620
Down payment (NerdWallet, updated Jul 17, 2026): at least 20%
Reserves (NerdWallet, updated Jul 17, 2026): three to six months of mortgage payments
Typical DSCR loan rates (NerdWallet, updated Jul 17, 2026): 6% to 8%
Property condition (NerdWallet, updated Jul 17, 2026): rent-ready, with no fixer-uppers

NerdWallet also says DSCR loans can be used to buy short-term and vacation rental properties, and that they cannot be used to buy a primary residence. In Boulder those two lines collide. The only legal short-term rental is the owner's own principal residence, and a DSCR loan is not for a home you live in. For an investor, the Boulder DSCR question is therefore a long-term rent question.

Why can't short-term rental income support a DSCR on an investor-owned Boulder property?

Short-term rental income cannot support a DSCR on an investor-owned Boulder property because the City of Boulder licenses short-term rentals only at the owner's principal residence, held by a natural person, trust or nonprofit, and a license is no longer valid once the property is sold. The seller's nightly income does not transfer to you.

The City of Boulder's short-term rental licensing page sets out the rules. A short-term rental is a property rented for 29 days or fewer at a time. The rental must be the owner's principal residence, the name on the license must match the name on the deed, and the owner must be a natural person, trust or nonprofit organization. Licenses run for a four-year term, and the owner must file an annual affidavit and fee by the license's anniversary date to certify continued principal residence; missing it means revocation. The page also says short-term rental is no longer an approved use for any property with an accessory dwelling unit.

Short-term rental definition (City of Boulder): rented for 29 days or fewer at a time
Who can hold the license (City of Boulder): the owner, at the owner's principal residence, as a natural person, trust or nonprofit
License term (City of Boulder): four years, with an annual principal-residence affidavit
On sale (City of Boulder): the license is no longer valid
Fees (City of Boulder): $190 rental license fee, $25 one-time business license fee, $20 with each annual affidavit

Put that against a typical investor purchase. An LLC buying a Hill house to rent is not a natural person and does not live there, so a pro forma built on nightly rates describes income the property cannot legally produce for that owner. A listing that shows strong short-term rental history is showing the seller's license, which ends at the sale. Model the ratio on 30-day-plus leases, and treat any nightly figure in a seller's package as irrelevant to your loan.

How does Colorado's HB24-1007 change a by-the-bed rent roll near CU Boulder?

Colorado's HB24-1007, effective July 1, 2024, bars local governments from limiting how many people live together in a dwelling based on familial relationship, so a by-the-bed rent roll on University Hill is now tested against bedroom size and safety codes rather than Boulder's old unrelated-occupant count.

The signed act adds section 29-20-111 to the Colorado Revised Statutes. It says a local government shall not limit the number of people who may live together in a single dwelling based on familial relationship, and it lets local governments keep occupancy limits based only on demonstrated health and safety standards, such as building code, fire code or state water and wastewater standards, or on affordable housing program guidelines. The act took effect July 1, 2024.

The City of Boulder's occupancy page explains the local result. City code enforcement administratively ceased enforcing the land use code's occupancy rules based on the number of unrelated persons per unit, and the city said it would prepare ordinance revisions for Council. The city continues to enforce the International Property Maintenance Code, which requires each bedroom to be no fewer than 70 square feet, with a minimum of 50 square feet per occupant of a bedroom (IPMC sec. 404.4.1), and sets minimum living and dining areas by the number of occupants.

For a DSCR loan, that moves the argument from relationships to measurements. A five-bedroom house leased by the bed can now count every lawful bed, but each one has to survive a tape measure, and a den rented as a bedroom is a line a lender or appraiser can strike. Ask each lender whether it will size on the lease total or on the appraiser's market rent; the trade-offs are set out in which rent a DSCR lender uses. Then measure every bedroom before you sign a by-the-bed lease that the loan depends on.

What does a long-term Boulder rental need before a lender counts its rent?

A long-term Boulder rental needs a city rental license before it is rented, because the city requires every rental property to hold one, and licensing brings an inspection, the SmartRegs basic energy efficiency standard and, for owners outside Boulder County, a local agent who can respond within 60 minutes.

The City of Boulder's long-term rental licensing page says standard long-term rentals are rentals of 30 days or more at a time, that obtaining the license is the owner's responsibility, and that discovering an unlicensed rental will result in legal action. The licensing process runs through a rental inspection, and single-family homes certify outdoor lighting compliance in that inspection. The SmartRegs ordinances require all rental housing to meet a basic energy efficiency standard. Owners who do not live in Boulder County must designate a local agent who can respond to the property within 60 minutes. The page also says a license term can be reduced to 12 months for land use violations or to 24 months for housing code violations.

Each of those lines touches the loan. A house that needs SmartRegs upgrades before it can be licensed is not yet the rent-ready property NerdWallet says a DSCR loan expects, so it may need a short bridge or renovation loan first and a DSCR refinance after. A reduced license term is a flag a lender will ask about. And the local agent is a recurring cost that belongs in the expense side of your model even though it is not in the DSCR payment.

What does the DSCR math look like on an illustrative University Hill house?

On an illustrative four-bedroom University Hill house worth $1,000,000, a $750,000 loan at 7.00% produces a DSCR of about 0.96 on a $5,600 lease total and about 0.82 on a $4,800 market-rent opinion, both below the roughly 1.25 NerdWallet says lenders typically want (our arithmetic).

Every input below is an assumption chosen for illustration, not a quote, an appraisal or a Boulder rent survey. The 7.00% rate sits inside the 6% to 8% range NerdWallet lists as typical for DSCR loans.

To reach 1.25 on $5,600 of rent, the payment can be no more than $4,480. Take out $850 of taxes and insurance and $3,630 is left for principal and interest, which at 7.00% over 30 years supports about $545,600, roughly 55% of value. On the $4,800 market-rent opinion the same math supports about $449,400, roughly 45% (all our arithmetic). NerdWallet notes that a DSCR loan can sometimes be had at 1.00 or lower, at a higher rate and with more money down.

That is the Boulder trade in one table: purchase prices that long-term rent does not fully cover push leverage down, and the gap between the lease total and the appraiser's rent decides how far. Run your own numbers in the DSCR calculator before you write an offer, and settle which rent each lender will use before you rely on its leverage.

What do HUD and Census data say about Boulder-area rents and new supply?

HUD's FY2027 Fair Market Rents for the Boulder, CO MSA run from $1,520 for an efficiency to $3,146 for four bedrooms, each below HUD's revised FY2026 figure, and the Census Bureau counted 1,534 units in 39 buildings of five or more units permitted across the metro in 2025.

HUD defines Fair Market Rents as estimates of 40th percentile gross rents for standard quality units within a metropolitan area. They are a metro benchmark, not the rent on a Hill lease or a Gunbarrel townhome, and they include utilities. Their direction is still useful context for a long-term rent assumption.

Sources: HUD FY2026 revised and FY2027 Fair Market Rent data files. FMR methodology can change between years, so read the change as a benchmark move, not a measured rent decline.

On supply, the Census Bureau's 2025 annual permit file for the Boulder metro shows 428 single-family units, 12 two-unit buildings with 24 units, 4 three-or-four-unit buildings with 15 units, and 39 buildings of five or more units holding 1,534 units, about 39.3 units per building (our arithmetic). New rental supply is arriving mostly in large apartment buildings that compete for the same long-term tenants as a Table Mesa duplex or a Gunbarrel townhome. The metro is Boulder County, which also takes in Louisville and Lafayette; those cities set their own rental and short-term rental rules, so the City of Boulder rules above apply inside Boulder city limits only. Check the town's code before modeling income on a Louisville or Lafayette property.

How do you get a Boulder DSCR loan placed?

You get a Boulder DSCR loan placed by sending lenders a package built on long-term rent, with the rental license, the leases, bedroom measurements and the market-rent support in one place, so every term sheet sizes the same ratio. YieldStack is an AI-native commercial mortgage brokerage that arranges financing for commercial real estate investors.

Start with a brokerage on a Boulder DSCR loan for a concrete reason: the deciding questions here, which rent the lender will use, whether a by-the-bed lease survives the bedroom measurements and whether the license is clean, are answered differently by different lenders, and the answers set your leverage. YieldStack's software matches the deal against 20,000+ loan programs and compares the options, and human brokers then structure the request, negotiate on the borrower's side 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:

• Purchase contract or current deed, address and parcel number
• The City of Boulder rental license, or the application and inspection status
• Signed long-term leases, or a rent schedule with comparable long-term rents
• A floor plan with every bedroom measured, if the rent roll is by the bed
• Taxes, insurance and any homeowners association dues for the payment line
• SmartRegs status and any upgrade budget
• Your entity documents and reserves

Local context is on the Boulder market hub. When the package is ready, send the Boulder rental 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

Yes, a DSCR loan works on a Boulder rental or student rental, but only on long-term rent. The city's short-term rental license belongs to an owner-occupant and ends at sale, so nightly income cannot carry an investor's ratio. After HB24-1007, a by-the-bed rent roll counts every bedroom that meets the property maintenance code's 70-square-foot and 50-square-foot-per-occupant tests, and nothing more. Get the rental license and SmartRegs status settled, measure the bedrooms, and find out which rent each lender will use, because in Boulder that choice decides how much the loan can be.
