Same-building condo comparable sales can provide strong evidence about demand for a building while offering a weak match for the unit you’re pricing. A comparable sale, or “comp,” is a completed transaction used to help estimate another property’s value. Shared amenities and association conditions make a neighbor’s sale useful, but differences in view, layout, condition and ownership rights can limit what its price tells you.

What a sale in the same building establishes

Fannie Mae’s condo appraisal requirements call for examining both the project and the individual unit, including its position within the project, amenities and association charges. A neighbor’s sale therefore deserves attention without necessarily setting your price.

Freddie Mac’s guidance for established condo projects likewise calls for sales within the project when they provide the best indications of value. That qualification makes comparability central to the choice. See Guide section 5605.6(g), in the February 4, 2026 edition.

Separate floor, view, stack and condition

A floor number is a clue to investigate. Suppose two otherwise similar units sit above and below a neighboring roofline. Their views may differ sharply even though they are only one floor apart. Several floors higher, another increase in elevation might barely change the outlook. Neither situation supports a universal price per floor.

Examine the view from the rooms buyers use, its extent and its obstructions. Freddie Mac’s appraisal data FAQ explains that two properties classified as having beneficial water views can still warrant an adjustment because the market distinguishes their quality.

For this comparison, “stack” means units positioned above one another. Check whether they share a layout and orientation. Compare corner versus interior positions, balconies, daylight, privacy and exposure to elevators or mechanical equipment. A matching unit suffix starts that investigation; it does not finish it.

Document condition with sale-time photographs and descriptions: which kitchens, bathrooms and systems were updated, and what repairs remained? A renovation invoice records spending; it does not by itself establish the value buyers recognize.

Any appraisal adjustment for view needs market evidence. Fannie Mae requires adjustments based on buyers’ demonstrated reactions, rather than arbitrary formulas. In a pricing analysis, avoid counting the same benefit twice—for example, attributing one price difference fully to both elevation and the view it creates.

When another building offers a stronger comparable

Look beyond the building when another sold unit better matches the combination buyers would choose: layout, size, condition, outlook and parking, along with project amenities and costs. A nearby tower’s updated penthouse may be less informative than a similar unit several blocks away.

Fannie Mae’s comparable-sales guidance permits sales from competing market areas with an explanation of their relevance and differences. It also recognizes that an older, better match can be more useful than a recent sale needing numerous adjustments. New and recently converted projects have additional selection requirements.

Compare association costs and parking rights

Identify what HOA fees cover

Before treating a lower monthly bill as an advantage, identify the utilities, services, amenities and reserve funding covered by homeowners association (HOA) fees. Check the charge for each unit and the period when it applied.

The Fannie Mae/Freddie Mac condo appraisal form separately records utilities included in assessments, additional facility charges, budget analysis and parking arrangements. Those distinctions make a seller’s comparison sheet more useful than one column labeled “HOA.”

Trace the assessment and the underlying repair

Obtain the assessment notice, remaining balance, payment schedule and related repair information. Establish what buyers knew when each sale went under contract and whether the seller paid the balance or the buyer assumed an obligation.

Fannie Mae’s project standards, updated August 5, 2026, require lenders to examine an assessment’s purpose, approval, amount and expected payoff. An assessment tied to an unresolved critical repair makes the project ineligible under those standards.

Paying an assessment and resolving the underlying building problem are separate events. A sale negotiated before that problem became known needs further investigation before it can represent current demand.

Verify the parking rights that transfer

Check whether parking is owned, assigned under association documents, or available through a separate rental arrangement. Record the space, fees and rights that transfer with the sale. The condo appraisal form distinguishes assigned from owned parking.

Have a local real estate attorney resolve unclear parking rights or assessment obligations before using them in a pricing claim.

Check when and how the sale was negotiated

Record contract dates as well as closing dates. Fannie Mae’s March 2026 Appraiser Update emphasizes analyzing market changes from the comparable’s contract date to the appraisal’s effective date. Broader home-price evidence supplies context; the analysis still needs evidence relevant to competing condos.

Verify transaction terms, including closing credits and rate buydowns. Freddie Mac’s July 30, 2024 guidance on concessions explains that a concession’s effect on price need not equal its cost to the seller. Automatically deducting a credit dollar for dollar does not establish market value.

A hypothetical comparison: three sales, different uses

Suppose the unit being priced is a dated, 1,200-square-foot, two-bedroom unit on the 12th floor, with an open view and one owned garage space. Assume these fictional sales closed in the same month under similar market conditions, without concessions or special assessments.

These assumed facts do not establish a value or a defensible average. The first sale helps examine the view difference. The second needs evidence separating several advantages. The third may offer the strongest unit comparison, but its project and fee differences still need analysis.

How an agent’s pricing analysis differs from a lender appraisal

An agent’s comparative market analysis, or CMA, helps a seller choose an asking-price strategy. A lender appraisal provides an independent, documented opinion of value for the lending assignment. Colorado’s real estate regulator explains this distinction between CMAs and appraisals. Fannie Mae and Freddie Mac requirements apply within their lending frameworks; they do not turn an agent’s CMA into an appraisal.

Request a pricing range that explains which sales deserve the most weight and what supports any adjustments. Keep active asking prices separate from completed transactions, and mark unverified details as unknown. Use the range alongside the preparation and timing decisions in our selling guides. Before choosing an asking price, ask which missing fact could change the conclusion.
