Boutique Conversions: The Value-Add Underwrite

The asset is manufactured, not bought#

A boutique hotel conversion is a manufacturing process wearing a real estate costume. The principal does not acquire a hotel. The principal acquires a building, a change of use, a capital programme and an operating agreement, then assembles them into an asset that did not exist on the day of purchase. The purchase price is raw material. The value is made afterwards, or it is not made at all.

The value-add label is precise, and it is not a marketing register. Core capital buys stabilized income and accepts a low yield for low execution risk. Value-add capital manufactures the income that core will later buy, and is paid for the manufacturing risk it carries in the interim. A conversion sits squarely in the second box. The return is the spread between a distressed-in basis and a stabilized-out valuation, net of the cost and the time it takes to close that spread.

Everything in this piece is a lever on that one spread. Acquisition basis, capital expenditure, authorizations, and the operator are not separate subjects. They are the four inputs to a single equation, and an error in any one of them is an error in the whole. The discipline is to underwrite the spread, not to admire the building. The building is the easiest part to fall in love with and the least load-bearing part of the return.

The capital is flowing, and it is flowing to value-add#

European hotels are no longer a recovery trade; they are an allocation. Pan-European hotel investment reached EUR 21.9 billion in 2024, the highest level since 2019, up 47.6% year-on-year and 8.2% above the ten-year average, on Savills' measured transaction data. Hotels were one of only two asset classes to beat both their prior year and their long-run average that year. This is not sentiment. It is settled volume.

And the mandate inside that volume has a name. Savills' inaugural European Hotel Investor Sentiment Survey, taken in December 2025, found a decisive preference for higher-returning value-add strategies and a net buyer position overall. Cushman & Wakefield, reporting a German hotel market that grew more than 50% to roughly EUR 2 billion in 2025, put it plainly: value-add and operator-free hotels dominate the market. The capital is not chasing finished product. It is chasing the manufacturing spread.

The reason is arithmetic, not fashion. Bain & Company's framing, cited by Savills, is that 12 is the new 5: an EBITDA compound growth rate near 12% is now required to deliver a 20% IRR over a five-year hold. Multiple expansion is no longer doing the work it did in the last cycle. Value has to be built inside the asset, through repositioning and operating performance, which is precisely what a conversion is engineered to do.

The acquisition is a cost-per-key arbitrage#

Conversion earns its return before the first invoice, in the basis. Ground-up development is expensive and getting more so. JLL put the 2023 cost per key for an urban full-service hotel at roughly USD 742,000, up 32% since 2019; Savills notes construction costs have risen 1.5 to 2 times over the past decade, eroding development feasibility. A building already standing removes the shell, the structure and much of the time from that stack. The arbitrage is buying an asset whose bones already exist below the cost of manufacturing those bones new.

The saving is real but the number is not a European constant, and we will not pretend it is. CBRE data cited for US office-to-hotel conversions runs USD 250 to USD 650 per square foot; a single US select-service re-flag was field-priced at USD 34,000 to USD 62,000 per key in fit-out alone. These are US benchmarks. There is no consolidated, published European conversion cost-per-key series we would anchor a European underwrite to, and importing US numbers into a European heritage scope is directional at best. We flag it rather than launder it.

What travels is the principle, not the figure. The conversion thesis holds wherever replacement cost is high, prime supply is constrained, and a standing building can be acquired below the cost of recreating its envelope. That describes most protected European city centres and resort locations. The specific per-key number must be priced on the specific building, by people who have opened one before, not read off a table.

The capex programme is the underwriting#

Capex is not a line item in a conversion; it is the deal. A boutique repositioning carries three distinct buckets, and confusing them is how budgets fail. First, the hard shell and systems: structure, envelope, mechanical, electrical, plumbing, life safety, vertical circulation. Second, FF&E, furniture, fixtures and equipment, which on full-service and upscale product runs an indicative USD 55,000 to USD 135,000 per key on the industry ranges. Third, the pre-opening and soft costs that bring the asset to first guest. On US full-service work, total project cost commonly lands at 1.4 to 1.65 times the construction contract; the multiplier is where undisciplined underwrites bleed.

The scope is dictated less by taste than by the brand standard, if there is a brand. Where a soft brand or operator flag is involved, brand standards can drive the majority of the fit-out scope, and the finish schedule is not fully the principal's to set. The luxury and soft-brand tier sits above USD 525,000 per key even in ground-up terms; a conversion to that tier inherits the same finish expectations against a fixed, sometimes awkward, existing structure. The building constrains the plan. The brand constrains the finish. The two rarely agree for free.

Contingency in a conversion is a structural input, not a rounding buffer. Standing buildings hide their liabilities behind finished walls, and a heritage envelope compounds the uncertainty. Underwriting a conversion at a new-build contingency is the single most common way the manufacturing spread evaporates between acquisition and opening. The contingency is not padding. It is the price of not being able to see inside the walls before completion.

Authorizations are the moat and the delay#

In Europe, the planning file is often harder to win than the building is to buy, and that is the point. A conversion to hospitality typically requires a change of use consent, and where the asset is protected the file passes through heritage control: the Soprintendenza and autorizzazione paesaggistica in Italy, the Architecte des Bâtiments de France regime in France, listed building consent in the United Kingdom. These are not formalities. They are binding, they are discretionary, and they set the true critical path of the project.

The precision of the constraint is the underwriting, and it must be named before acquisition, not discovered after. What can be demolished, what must be preserved, what can be added, how the facade may be treated, what use classes the local instrument permits, how long the competent authority has to respond and whether its opinion is binding: these are the conditions to underwrite. A conversion bought without a defensible read on its consents is not underwritten. It is a wager on a public body.

But the same barrier that slows the project protects the exit. Scarce consent is scarce supply. A boutique hotel that could not legally be replicated next door is an asset whose competitive set is capped by statute, not by capital. The friction in the entitlement is, correctly read, the durability of the income. The allocator who resents the delay is failing to price the protection it buys.

The operator is not a vendor, it is the value#

A boutique hotel is an operating business bolted to a piece of real estate, and the bolt is the operating agreement. The principal chooses among three structures, and the choice sets the risk profile of the whole return. A lease transfers operating risk to a tenant for a fixed or turnover rent, and prices to the tightest yields. A management contract keeps the operating risk with the owner and pays an operator to run the asset. A franchise buys the flag and the distribution but leaves operations with the owner or a third-party manager. Savills' data shows leased structures pricing well inside vacant-possession and franchise structures, precisely because the risk sits differently.

Under a management contract, the operator's economics are standardised enough to underwrite and negotiated enough to matter. The base fee typically runs 2.0% to 4.0% of total revenue, with 3.0% a common anchor on HVS's reading, payable whether or not the hotel is profitable. The incentive fee typically runs 5.0% to 15.0% of gross operating profit. Ramp structures are common, with the base fee stepping up over the first years. These are industry-standard ranges, not a quoted term sheet, and the effective economics turn on definitions: GOP versus AGOP, whether the FF&E reserve sits above or below the incentive line, and whether an owner's priority protects the owner before the operator is paid.

The operator is where a converted building becomes a brand, and where the exit multiple is decided. CBRE's brand analysis found the strongest brand family compounded RevPAR at 2.1% a year over 2014 to 2024 while the weakest contracted, a cumulative spread of 26% that, under leverage, can be the difference between profit and loss. The operator is not a service the principal buys after the building is done. The operator is the reason the finished building has an income worth capitalising.

Branded residences finance the hotel#

The branded residence is not a side product; it is increasingly the financial engine of the conversion. Savills reports that luxury branded residential schemes in Europe have grown from 18 in 2015 to 62 at the end of 2025, and are forecast to double again by 2032, with branded residences now integral to the majority of luxury hotel projects. The mechanism is direct: residential sales, taken up front, de-risk and part-fund the hospitality component that trades on a longer horizon.

The premium those residences command is real, well-sourced, and heavily caveated. Savills' Global Brand Premium Study puts the average branded-residence premium at roughly 33% over comparable non-branded stock, with resort locations near 39% and established and emerging cities near 30%. This is an industry estimate on an unweighted basis, and Savills is explicit that variance is high, with some emerging resort markets far more dispersed. A 33% average is a planning figure, not a promise on a specific unit.

For the conversion underwrite, the residence changes the sequencing of cash, not the quality of the asset. Selling keys as residences pulls capital forward and shortens the value-add exposure; it does not remove the obligation to deliver a hotel that performs, because the brand mark that carries the residential premium is only as good as the operation standing behind it. The residence is financed by the promise of the hotel. The order of operations matters, and it is the hotel that must be true.

The operator advantage#

Quality has separated from the market, and the separation is measured. Across selected major European markets, ultra-luxury RevPAR has risen 57% since 2019 against 47% for luxury and 24% for non-luxury, on CoStar data reported by Savills. The strongest luxury RevPAR is being achieved in resort markets, most notably France and Italy. Italy closed 2025 as the top European market for RevPAR growth since 2019, up 53% to EUR 159, with Rome's luxury segment up 46% and Milan's up 58% over the same period, on Cushman & Wakefield's reading. Trophy assets in irreplaceable locations are holding their yields while the rest of the market repriced.

A conversion is the instrument that puts new capital on the right side of that split. A standing building in a protected prime location, converted to a boutique or ultra-luxury standard and run by a credible operator, is a purpose-built way to buy into the segment that is compounding rather than the segment that is treading water. The value-add work is what converts a location advantage into an operating advantage. Location cannot be manufactured. The building around it, and the business inside it, can.

This is the discipline Victaura is built to run, and it is worth stating without embellishment. The firm's stated remit is the identification, conversion and repositioning of assets into boutique hospitality in prime and resort European locations. The advantage claimed is process: pricing the consent before the acquisition, sizing the capex against the real structure, and aligning the operator's economics with the principal's. Nothing in that claim is a projected return. It is a method, and the method is the product.

The structural weaknesses, honestly disclosed#

The cost data anchoring this strategy is largely American, and Europe is not America. The USD 742,000 ground-up figure, the USD 250 to 650 per square foot conversion range, and the USD 34,000 to 62,000 per key re-flag are US benchmarks, and the last is a single select-service case, not a luxury heritage scope. There is no published European conversion cost-per-key series of comparable authority. A European underwrite must be built bottom-up on the specific building; the figures here frame the shape of the problem, not the answer to it.

The pricing-power story is partly an inflation illusion, and the honest read says so. CBRE found that RevPAR for the brand families it studied was nominally up 9.3% since 2019 but down 10.9% in inflation-adjusted terms, with muted real growth attributed to shadow supply and added rooms. Luxury has outperformed, but the base is not as strong as the nominal headlines imply, and a conversion underwritten on nominal rate growth alone is underwritten on an illusion.

The moat cuts both ways, and the operator dependency is genuine. Heritage consent has no fixed timetable; the same discretion that protects the exit can strand capital for years or refuse the plan outright. Operator fee ranges are industry standards, not committed terms, and the effective economics hinge on definitions and on the owner's priority, which is negotiated, not given. The branded-residence premium is an unweighted study average with high dispersion. Every one of these is a place where a real conversion can lose the spread it was bought to capture. None of them is a reason not to do the work. All of them are reasons to do it precisely.

What this means for the operator and the principal#

For the principal, the conversion play is an underwriting of four numbers, not a purchase of one building. The acquisition basis, the fully-loaded capex with a heritage-grade contingency, the entitlement path with its real critical path, and the operator's fee and structure are the underwrite. A conversion priced on the building alone, or on US cost benchmarks alone, is not priced. The spread is captured by whoever prices all four before signing, and lost by whoever discovers any of them afterward.

For the operator, the discipline is sequencing. Win the consent before committing the capex. Size the capex against the structure that exists, not the plan that flatters it. Align the operating agreement so the principal is paid before the operator collects an incentive. And where residences finance the scheme, remember that the residential premium rests on a hotel that must actually perform. Do these in order and the value-add is manufactured. Do them out of order and it is merely hoped for.

The market is telling both parties the same thing in different registers. Capital is flowing to value-add and to quality; prime consented supply is scarce and getting scarcer; and returns must now be built inside the asset rather than borrowed from the cycle. A conversion, done with discipline, is the instrument that sits at the intersection of all three. It is not a cheaper way to own a hotel. It is a way to manufacture one that could not otherwise be built.
