An appraiser pulls into a driveway at La Cholla Airpark expecting a normal site visit. The house measures out fine: square footage, bedroom count, finishes, all of it maps to a familiar form. Then the appraiser walks past the house to the hangar, and the taxiway running from that hangar to a lit, 4,500-foot runway, and the form runs out of boxes to check. Fannie Mae and Freddie Mac guidelines have no clean category for a residential hangar attached to a private airstrip. So the hangar gets treated as an outbuilding, the taxiway gets treated as pavement, and the appraisal comes in lower than the contract price. That gap is not a pricing mistake. It is what happens when a national lending system built for standard subdivisions meets a property type it was never designed to measure.
The same mismatch shows up again once you get past financing and into governance. La Cholla Airpark is not run by a typical homeowners association. It operates as La Cholla Airpark, Inc., a private Arizona corporation in which homeowners hold shares rather than simply pay dues, and every transient pilot who wants to land there has to submit insurance verification directly to that corporation before touching down. That structure works well for deciding who can use the runway. It has been far less clean when it comes to raising money to maintain the runway, and that history is public record.
What "outbuilding" means on a lending form
The mechanics are worth spelling out, because they explain why hangar homes here take longer to sell and why cash buyers have an advantage that has nothing to do with taste.
Fannie Mae and Freddie Mac guidelines simply have no line item for "taxiway access" or "residential hangar." Lenders default to the most conservative reading available, which means the hangar gets valued the way a detached garage or shop building would be valued anywhere else, regardless of what it actually cost to build or what it means to a pilot buyer. Comparable sales compound the problem. Airpark transactions are rare enough nationally that appraisers frequently cannot find recent, truly comparable closings, and when a property is genuinely unique, the standard guidance is that the appraiser has to fall back on the best available sales and apply market-supported adjustments rather than a clean matched set. That is a polite way of saying the appraiser is estimating, not measuring.
Here is what that looks like on paper versus on the ground:
| What the appraisal form records | What actually sits on the property |
|---|---|
| Detached outbuilding, minimal added value | Hangar with taxiway connection to a lighted 4,500-foot paved runway |
| Standard residential lot | 7-acre minimum parcel, part of a 1,000-acre private airpark founded in 1972 |
| Generic subdivision comps | A buyer pool limited almost entirely to pilots who understand what the taxiway is worth |
The practical workaround that shows up across the aviation real estate world, not just here, is to split the financing rather than force it into one loan. Buyers finance the home conventionally, since the residential structure appraises normally on its own, and then cover the hangar separately through cash, a home equity line against another property, or a portfolio lender willing to underwrite based on its own judgment rather than a standard secondary-market template. None of that is exotic. It is simply a recognition that the mortgage industry's forms were not built with a taxiway in mind, so the deal has to be structured around that gap instead of against it.
The paperwork behind the runway
If the appraisal problem is about an asset category the lending system does not recognize, the governance problem is about a decision-making structure that has struggled to keep pace with its own infrastructure.
La Cholla Airpark was annexed into the Town of Oro Valley on July 6, 2005, which shifted zoning oversight from Pima County to the town while the airpark corporation kept control of the runway, taxiways, and internal roads. That internal governance runs on CC&Rs that require a super-majority vote to change assessment levels, and a shareholder petition on file shows that structure creating real gridlock: multiple ballots failed to modify assessment amounts or loosen the voting threshold, and one shareholder, Lonny Ferrin, filed a legal complaint over the resulting inability to fund road repairs. The petition proposed rewriting the relevant CC&R section with outside counsel and putting a settlement to a shareholder vote, with court intervention as the fallback if that vote failed.
Whatever the current status of that specific dispute, and a buyer's agent should confirm it directly against recent board minutes rather than assume it is resolved, the underlying lesson holds regardless of the exact date it happened. A corporation-and-shareholder structure with a super-majority requirement is a fundamentally different risk profile than a standard HOA that can raise dues with a simple board vote. If the roads or runway need work and the vote threshold cannot be met, the cost does not disappear. It sits unresolved, sometimes for years, while individual owners live with deferred maintenance they cannot unilaterally fix.
That same structural looseness is part of what let one of the airpark's most recognizable properties exist in the first place. Raytheon engineer Toshikazu "Ski" Tsukii built a two-story guesthouse out of a Boeing 737 nose cone, a 727 tail, and two 707 cabin sections, with a nearby pool covered by a 747 fuselage, and Oro Valley's building official at the time noted the design would not have cleared plan review in most of the town's other neighborhoods. Gil Alexander, then vice president of the airpark's homeowners association, put his finger on why it worked here: "The fact that we're all on seven acres or more made a difference." Large lots and light-touch covenants create room for that kind of individuality. They also mean a buyer cannot assume any given property matches a neighboring one in structure type, permitting history, or how it will show up on an appraisal.
What this changes at the closing table
None of this makes a hangar home a bad purchase or a hard sale. It means both sides of the transaction need to do work that a standard Oro Valley listing does not require.
- Request the current CC&Rs, corporate bylaws, and the most recent one to two years of board or shareholder meeting minutes before writing an offer, specifically checking for any pending assessment votes or unresolved maintenance disputes.
- Ask directly about reserve funds for runway, taxiway, and road maintenance, since a shareholder corporation with a high vote threshold can leave real deferred-maintenance costs sitting unfunded longer than a conventional HOA would allow.
- Confirm the runway specifications in writing: identifier 57AZ, a 4,500-foot lighted asphalt surface, Unicom frequency 122.975, and the airpark's own requirement that transient pilots carry occurrence-based liability coverage with at least a $1,000,000 combined single limit before landing.
- Before the lender orders an appraisal, prepare a package for the appraiser that documents what the hangar cost to build, what similar aviation properties elsewhere have sold for, and why taxiway access carries value even though the appraisal software has no field for it.
- Decide early whether the hangar will be financed as part of the home loan or funded separately through cash, a HELOC on another property, or a portfolio lender, since waiting until underwriting is underway to make that call adds weeks to closing.
Sellers benefit from doing the same homework before listing. A property with clean, current board minutes and a documented reserve position closes faster than one where a buyer's lender discovers open governance questions midway through underwriting.
This is the kind of transaction where a background in engineering and technical due diligence matters as much as a background in sales. The Bonn Team pairs that technical review with the presentation and negotiation work a property like this deserves, coordinating appraisal documentation, CC&R review, and lender strategy from the first showing through closing.
FAQ
Can I get a standard 30-year mortgage on a home at La Cholla Airpark? Generally yes for the residential structure itself. The complication is almost always the hangar, which conventional lenders typically classify as an outbuilding with minimal added appraisal value, so most buyers plan to finance the home and the hangar as two separate pieces.
Is La Cholla Airpark governed like a normal HOA? No. It operates as La Cholla Airpark, Inc., a private corporation in which homeowners hold shares, with CC&Rs that require a super-majority vote to change assessments. That is a materially different structure than a standard homeowners association and worth reviewing closely before you buy.
Do I need special insurance just to land here as a guest? Yes. The airpark requires any transient pilot to submit proof of occurrence-based liability coverage, with a combined single limit of at least $1,000,000, before a landing request will be approved.
