Inspirato launches real estate business

By Jeff Weinstein

September 14, 2021

Luxury travel subscription company Inspirato has announced a major strategic initiative to accelerate expansion of its growing portfolio with the launch of Inspirato Real Estate, which will assist potential vacation home buyers find a property to acquire and then lease back to Inspirato.

“We launched Inspirato Real Estate to add another dimension to our strategy to grow our Inspirato residence portfolio, so that we can offer more choices to Inspirato subscribers,” Founder and CEO Brent Handler told HOTELS on Tuesday. “Over time we realized that in addition to providing travelers with exceptional service and certainty for their vacations, we also deliver a valuable service to our residence landlord partners by providing them with a worry-free ownership experience available nowhere else. This is due to the fact that our homes are available exclusively to our closed network of Inspirato subscribers, a highly affluent, built-in audience with predictable booking patterns, which enables us to invest in and take care of our landlord partner’s homes like no one else.”

Inspirato leadership would not divulge a specific amount invested in the new venture, but did say it is investing significantly. “We have built an extensive broker partner network to provide local market expertise,” Handler said. “We have built up our own internal team to ensure we have expertise to work with families to help them find their perfect vacation home with the right balance of lifestyle benefits and investment return. And we are investing in marketing to build awareness about the Inspirato Real Estate value proposition to prospective home buyers.”

Launched in 2011, Inspirato is expected to go public in the fourth quarter of this year in a blank-check merger with Thayer Ventures Acquisition Corp. The deal gives the combined company an estimated enterprise value of US$1.1 billion. In addition to the special-purpose acquisition company merger, a private investment in public equity will contribute about $100 million to the deal.

Prospective buyers explore a vetted collection of properties in dozens of vacation destinations directly on the Inspirato Real Estate website. Once they decide where to buy, Inspirato Real Estate’s team connects them to a local real estate professional. Prior to closing, they receive a personalized lease overview and financial return profile, including a net income projection for their chosen property. At closing, they lease their new home to Inspirato.

The benefits for buyers, according to Inspirato:

At launch, Inspirato Real Estate is presenting a selection of properties in more than 50 luxury vacation destinations including Vail, Colorado; the California wine country; Park City, Utah; Scottsdale, Arizona; Rosemary Beach, Florida; and Los Cabos, Mexico.

Existing homeowners can submit their properties for consideration for the Inspirato portfolio and, if accepted, are eligible to receive the same benefits as new buyers, including a lease that provides for fixed rental income.

Inspirato connects buyers with local real estate partners to help them select and close on their vacation home, charging no fees directly to the buyer. “To the contrary, when we lease their home for our portfolio, we pay buyers predictable fixed rental income,” Handler said. “When a buyer purchases one of our featured homes and leases it to us, we provide them with fixed rental income and cover full property management services – there are no ongoing fees for the buyer.”

Unlike typical online broker sites, under Inspirato leases, Handler said it pays rent each month regardless of bookings. “We work with each buyer to help them achieve their specific goals. As a result, the return profile is different for each home, and varies by market, asset type, desired owner usage, and other factors,” he said. “Our goal is to provide the best possible total return for buyers through the benefits provided by our Inspirato lease, which include a fixed rental return greater than market due to our built-in demand base, expert property management service to help maximize appreciation, and flexible owner usage together with a complimentary Inspirato Club subscription.”

The goals outlined by Inspirato on this venture is help it meaningfully increase the pace at which they add new residences to the Inspirato portfolio. “This includes building additional scale in our existing core destinations, and also adding new destinations for our subscribers to visit with us,” Handler said.

The biggest challenge? Markets are tight in many luxury real estate destinations right now, according to Handler. “Homes often go under contract with multiple offers the first day they are listed,” he said. “So, we need to ensure our team is vigilant, educated, and highly responsive.”

Denver Business Journal

Luxury travel firm launches new real estate division to grow portfolio

By Ed Sealover

September 14, 2021

As it prepares to become publicly traded later this year, luxury travel firm Inspirato is adding a new facet to its business that officials believe could grow its number of properties by more than 50% and boost its appeal as the club of choice for more potential customers.

On Tuesday, the Denver-based company launched Inspirato Real Estate, through which it will seek to connect potential purchasers of luxury properties to homes and condos already on the market with the goal of getting those buyers to add the properties to its portfolio. The site lists properties that are for sale in 19 states, two U.S. territories and eight foreign countries that Inspirato would like to manage and offers minimum annual leasing revenue that the company would guarantee to the potential homeowners.

The move is an outgrowth from what Inspirato has been doing since founder and CEO Brent Handler launched the firm in 2010. Inspirato currently manages, staffs and maintains exclusive luxury vacation homes that club members can access for a nightly fee. The company differentiates itself from other luxury travel clubs because rather than buying homes throughout the Western Hemisphere, it leases the properties and controls the experiences by managing them tightly, offering buy-in to the club at slightly lower rates than some of its competitors.

But by putting up a specific website and going so far as to identify hundreds of properties it would accept into its portfolio, Handler believes Inspirato is creating almost a one-stop service that will attract real-estate purchasers who know they immediately can generate revenue. And during an 11 a.m. interview Tuesday, he said that he’d already received “hundreds” of responses in just the first two hours the website had gone up, using only email to notify potential partners rather than a marketing campaign that he intends to launch Wednesday.

“My estimate is we will grow the portfolio rapidly,” Handler said. “It is infinitely harder to find houses than to find members … It’s a demand-driven market. So, when you bring on inventory, you become a differentiated product.”

Inspirato now has a collection of some 385 properties that members reserve and rent, and the company is on pace to generate $220 million in revenue in 2021. But its 2022 plan calls for $366 million in revenue — a 66.4% increase — and to achieve that goal it most boost its supply of housing significantly to accommodate more customers and more bookings.

Inspirato took a big hit at the start of the coronavirus pandemic, laying off 100 of its roughly 600 employees and seeing demand fall to nearly nothing for about three months. But since the end of May last year, demand and revenue have grown substantially, as more high-net-worth travelers are eschewing shared spaces like hotels in favor of homes where they can vacation in locations from Breckenridge to the Bahamas.

The company has raised some $85 million over the past 11 years and has substantial cash reserves on its balance sheet to fund the home-leasing spree that Handler is hoping Inspirato Real Estate will launch. But it also announced in June that it will go public sometime in the final quarter of this year through a merger with special purpose acquisition company Thayer Ventures Acquisition Corp. (Nasdaq: TVAC) that pinpoints the estimated value of the combined company at $1.1 billion.
