KENNA REAL ESTATE GROUP · COLORADO RENTAL PROPERTY GUIDE
Rental Property Buying Checklist for Colorado
A rental property does not work because the listing shows a good rent number.
Before you buy, prove five things:
- The property can be used the way you intend.
- The rent is supported by something more than an estimate.
- The expenses still leave enough margin.
- The financing works with the property and rental plan.
- The condition does not create repairs that erase the economics.
Kenna Real Estate Group can help you evaluate the real estate, available leases and property records, comparable properties, condition questions, and offer strategy. Your lender, insurer, attorney, tax professional, property manager, and local jurisdiction should answer the questions that belong in their lanes.
01
Start With the Rental Plan
Before you analyze the listing, write down what you actually intend to do with the property.
Are you buying:
- a single-family long-term rental
- a condo or townhome rental
- a duplex or other small multifamily property
- a home you will occupy while renting another unit or space
- a property with an existing ADU
- a tenant-occupied rental
- a vacant property you intend to lease after closing
Those plans can require different financing, records, leases, inspections, insurance, association review, and local-rule checks.
Do not let the listing label decide the strategy for you.
02
1. Verify That the Property Can Be Used the Way You Expect
A listing may describe:
duplex
ADU
basement apartment
mother-in-law suite
separate rental space
second kitchen
private entrance
Treat those phrases as clues.
They do not, by themselves, establish:
- legal unit count
- permitted construction
- allowable rental use
- separate utility status
- occupancy approval
- financing treatment
For a Denver Property
Start with the official property record and permit history.
Denver's property system lets you search an address for assessment and property information, while the city's e-permits system allows address-level permit and inspection searches.
City and County of Denver · Property Information
City and County of Denver · Building Permit Status
Use those records to identify questions.
Do not assume that finding—or not finding—a permit resolves every legal-use or condition issue.
If the unit count, ADU, conversion, or use materially affects the investment, get the appropriate local or legal answer before relying on the income.
03
2. Separate Rent Being Collected From Rent Being Projected
This is one of the most important distinctions in rental-property underwriting.
There are several different rent numbers you may encounter:
Current Contract Rent
What an existing lease says the tenant is paying.
Rent Actually Collected
What the owner has actually been receiving.
Market-Rent Estimate
What a broker, appraiser, property manager, lender, listing agent, or rental-data source believes the unit could rent for.
Pro Forma Rent
What someone hopes or projects the property may generate after a change.
Those numbers should not all be treated as equally certain.
If a listing says:
“Unit should rent for $2,400.”
ask:
What supports $2,400?
04
If the Property Is Already Rented, Ask for the Rental File
Before relying on existing income, request the available documents that matter to the purchase.
Depending on the property, that may include:
- current leases
- lease expiration dates
- amendments or renewals
- rent roll
- payment records when available
- security-deposit information
- utility responsibilities
- concessions
- parking or storage arrangements
- other recurring charges or credits
Then compare the documents with what the listing says.
Questions Worth Asking
Is every unit occupied?
When does each lease expire?
Are any tenants month-to-month?
Who pays water, gas, electric, trash, internet, lawn care, or snow removal?
Are there concessions that make the headline rent look higher than the effective rent?
Is any income coming from parking, storage, laundry, or another source?
If an existing lease materially affects the purchase, have the appropriate professional review the lease and current Colorado requirements rather than assuming the new owner can immediately rewrite the arrangement.
Colorado landlord-tenant law includes state requirements in addition to the lease itself, and local requirements can add another layer. (Colorado General Assembly)
05
3. Make the Property Pencil With Real Expenses
Rental-property VOC often reduces the whole decision to:
“Does it pencil?”
That is useful—as long as the spreadsheet includes expenses that actually exist.
Start with gross rent.
Then account for the costs that apply to the property.
Property Taxes
Use the actual parcel rather than a generic Front Range tax percentage.
Insurance
Get an investment-property insurance quote.
Do not assume the seller's premium or a standard owner-occupied homeowners estimate will apply to you.
HOA
If applicable, include current dues and investigate assessments, rental restrictions, insurance, and owner responsibilities.
Owner-Paid Utilities
A property with shared water, heat, trash, or another common utility can have a different expense structure from separately metered units.
Maintenance and Repairs
Do not set these to zero because the property looks good today.
Vacancy
A fully occupied property today does not mean zero future vacancy.
Property Management
If you do not intend to manage the property yourself, include a realistic management expense.
If you intend to self-manage, decide whether the time and operational work are part of the return you are willing to accept.
Capital Expenses
A roof, sewer line, furnace, water heater, exterior work, or major common system can create costs that ordinary monthly maintenance does not capture.
06
Do Not Use One Percentage as a Substitute for Underwriting
Rules of thumb can be useful for screening.
They are poor substitutes for the actual property.
Do not decide a Colorado rental solely because it meets:
- a 1% rule
- a cap-rate threshold
- a cash-on-cash target
- another shortcut
Those metrics can help compare possibilities.
They do not tell you whether:
- the rent is real
- the unit is legal
- the roof is near replacement
- the HOA limits rentals
- the sewer needs work
- taxes or insurance are materially higher
- a lease creates an obligation you did not model
Use shortcuts to find questions.
Use property documents and numbers to answer them.
07
4. Keep Your Investment Math Separate From the Lender's Rental-Income Math
This is a common source of confusion.
Your lender is deciding how much rental income can be used for mortgage qualification.
You are deciding whether the property is a good investment.
Those are different calculations.
For example, Fannie Mae's current conventional guidance generally applies a 75% factor when qualifying rental income from certain leases or appraisal market-rent forms, with the remaining 25% intended to account for vacancy and ongoing maintenance. That is an underwriting rule for applicable Fannie Mae loans—not a universal property cash-flow formula. (Fannie Mae Selling Guide)
Fannie Mae · Current Rental Income Guidance
Your lender decides what applies to your loan.
Bring the Property to the Lender Early
Provide the lender with the property type and intended use.
For a rented or multi-unit property, the lender may need information involving:
- leases
- market rent
- appraisal
- occupancy
- reserves
- existing real estate owned
- property type
- other loan-specific documentation
Do this before writing an offer that depends on rental income being counted in a particular way.
08
If You Plan to Occupy the Property First, Say That Up Front
Owner-occupied financing and investment-property financing can be materially different.
If your plan is:
live in one unit and rent the other
or
occupy the home while renting an existing legal unit
tell the lender exactly that.
Do not describe the property as a normal primary residence and explain the rental plan after the offer is accepted.
The occupancy plan can affect:
- financing
- rental-income treatment
- property type
- insurance
- appraisal
- offer structure
09
5. Inspect the Rental Property as a System
A single-family rental and a small multifamily property should not always be inspected with the same mental checklist.
For multiple units, identify what serves:
one unit
versus
the entire property.
Heating and Cooling
Separate systems or shared?
Who controls them?
Electrical
Separate panels or shared service?
Plumbing
Where are the shutoffs?
Are units separately supplied or metered?
Water Heaters
One per unit or common?
Roof and Exterior
One failure can affect every unit.
Sewer and Drainage
A shared sewer problem can affect more than one rent stream.
Laundry
In-unit, shared, owner-provided, or tenant-provided?
Parking
Deeded, assigned, garage, driveway, alley, or street?
Does the actual parking match the number of occupants the investment assumes?
Storage and Access
What spaces belong to which unit?
How does the owner access mechanical systems without entering tenant-only areas?
A four-unit property with four rents can also mean four interiors plus shared systems that deserve closer review.
10
Multiple Units Need a Unit-by-Unit File
For a duplex or small multifamily property, build a simple worksheet for each unit.
Track:
- current rent
- lease end date
- deposit
- bedrooms and baths
- condition
- utilities
- parking
- appliances
- needed repairs
- market-rent evidence
Then maintain a second list for common property systems.
That helps prevent:
“The building rents for $7,000 per month”
from hiding the fact that one unit needs substantial work, another lease is ending, and the roof serves everyone.

When you are ready to compare current inventory:
11
Check the HOA Before Buying a Condo or Townhome Rental
Do not assume:
“Rentals are allowed because there are already tenants in the complex.”
Review the current association documents.
Questions can include:
- rental restrictions
- minimum lease periods
- caps or waiting lists
- registration requirements
- move fees
- parking
- insurance
- assessments
- owner maintenance responsibilities
A condo with attractive rent and a manageable mortgage can still fail the investment plan if the association restrictions do not fit your intended use.
12
If the Rental Is in Denver, Check the License Before You Rely on the Plan
Denver currently requires a residential rental property license for property offered or operated as a residence for 30 days or more at a time. The city also requires qualifying inspections as part of the licensing process. (Denvergov)
City and County of Denver · Residential Rental Property Licensing
If the Property Is Already Licensed
Check the current license status.
Do not assume the existing owner's license simply solves the issue after ownership changes. Denver states that a residential rental license is valid for four years unless ownership changes. (Denvergov)
If It Is Not Licensed
Find out what the current inspection and application requirements would be.
Make that part of the purchase plan rather than discovering the issue after you expect to place a tenant.
13
Long-Term Rental and Short-Term Rental Are Different Plans
Do not evaluate a Denver property as:
“I can always Airbnb it if long-term rent is weak.”
Denver treats those uses differently.
The city currently requires a short-term-rental license for stays of fewer than 29 nights and requires the short-term rental to be the operator's primary residence. Long-term residential rental licensing applies to rentals of 30 days or more. (Denvergov)
That makes short-term-rental eligibility a threshold issue, not an alternate revenue column you add later.
Check Denver Short-Term Rental Eligibility →
Outside Denver, verify the current rules for the actual city or county.
14
Colorado Landlord Rules Belong in the Due-Diligence Plan
Buying the property and operating the rental are different stages.
But if the investment only works under assumptions about:
- existing leases
- security deposits
- rent increases
- application criteria
- tenant notices
- habitability
- fees
- lease termination
do not leave those assumptions unverified.
Colorado has statewide landlord-tenant requirements in addition to the lease, and local governments can have additional rules. The Colorado General Assembly's Legislative Council maintains a landlord-tenant law overview, but current statutes and local rules control the particular situation. (Colorado General Assembly)
For a tenant-occupied purchase or a plan that depends on changing an existing tenancy, have the appropriate attorney or property-management professional review the actual circumstances.
The purchase spreadsheet should not depend on a legal assumption nobody has checked.
15
Do Not Forget the Insurance Change
A rental property is not automatically insured the same way as an owner-occupied home.
Tell the insurer how you intend to use the property.
That becomes especially important with:
- multiple units
- owner occupancy plus tenants
- vacancy during renovation
- older roofs
- foothills properties
- short-term rentals
- association properties
Colorado's Division of Insurance maintains consumer information on homeowners and property insurance, including Colorado hazards such as hail, wildfire, flood, and windstorm. (Colorado Department of Insurance)
The key purchase question is simpler:
Can I insure this property for the use I am underwriting, and what will it cost?
16
Stress-Test the Property Before You Call the Cash Flow Real
Run a second version of the numbers.
What happens if:
One Unit Is Vacant?
Can the property carry itself?
Rent Is Lower Than Projected?
Does the investment still make sense?
Insurance Costs More?
What happens to cash flow?
A Major Repair Arrives in Year One?
Do you have reserves?
Property Management Becomes Necessary?
Does the return still work?
A Tenant Turns Over?
Have you accounted for cleaning, repairs, leasing time, and vacancy?
The point is not to invent the worst possible scenario.
It is to find out whether the investment only works when nothing goes wrong.
17
Before You Make an Offer
Use this final rental-property checklist.
Use
Does the intended rental use work for the property and jurisdiction?
Units
What do the records support?
Rent
What is actually being collected?
What is only projected?
Leases
What obligations are already in place?
Expenses
Have you included taxes, insurance, HOA, utilities, maintenance, vacancy, management, and capital expenses that apply?
Financing
Has the lender reviewed the property type, occupancy plan, and rental-income documentation?
Condition
Have you inspected each unit and the common systems?
Licensing
Does the city or county require a rental license or inspection?
Association
Does the HOA allow the rental plan?
Insurance
Does the quote match the intended use?
Reserves
What happens if a repair or vacancy occurs shortly after closing?
If the deal depends on a missing document or an unverified assumption, that is the next question to solve.
