What does co-ownership actually cost?

Every Friday afternoon, on the drive up to our vacation home in eastern Washington, I feel the same shift. The week goes quiet and the weekend opens up. Buying it is one of the best decisions my family has made, and not because of anything you can put in a spreadsheet. It's where our favorite memories live.

There's a quieter side to owning a second home that most people don't talk about. The average vacation homeowner uses their property about six weeks a year, per the NAR Vacation Home Counties report. That means for roughly 46 weeks, the house sits empty. Every night the lights are off, the real cost of the nights you do spend there climbs. Call it a cost-to-memory ratio. The more you use the home, the cheaper each memory gets. The less you use it, the more each one costs you.

That ratio is what makes co-ownership worth a second look. You buy a piece of the home that matches how you'd actually use it. You own real property and build equity, which a timeshare will never give you. Most buyers don't know co-ownership is a real option. Those who have heard of it often confuse it with a timeshare. This article walks through the financial side so you can see what a fraction actually costs and what you get in return.

It depends on the home, how much of it you own, and a handful of assumptions about tax, insurance, maintenance, utilities, HOA, and property management. Here's a concrete example to anchor the math.

Take a $2 million vacation home. Four families each buy a 25% fraction. Here's how the costs compare:

That's roughly $1.58 million in Year-1 savings. Each family still owns real property, builds equity, and gets about 90 nights of use per year, roughly 12 to 13 weeks. Owners book as they go, holding at most half their allowance at a time outside the holidays, so no one family can claim the whole calendar.

Co-owners also pay Klasma a flat annual platform fee for the home, divided by ownership. It is never a percentage of what the home spends. It covers scheduling, bookkeeping and owner statements, the LLC's tax return and each owner's K-1, the annual LLC filing, and keeping the operating agreement current. The price isn't set yet, so it isn't in this table.

Here's the fractional picture across Year 1, ongoing annual costs, and cost per week:

After 10 years

Year 1 is only part of the picture. Most vacation-home buyers plan to own for a decade. NAR's Investment and Vacation Home Buyers Survey reports an expected hold period of about 10 years.

Two real-world factors change the picture over that decade. First, whole ownership at this price point is almost always financed, typically with 20% down on a 30-year mortgage. A small number of fractional operators have begun offering financing, but most fractional buyers pay cash. Second, the home appreciates, so some of the money put in comes back at sale.

Here's the net 10-year cost of ownership, assuming the whole buyer puts 20% down on a $1.6M mortgage at 6.5%, both sell at year 10, and the home appreciates at 4% annually (with 7% selling costs):

The 25% owner's stake appreciates with the property, so their $690K cash out is largely recovered at sale. The whole owner's biggest unrecoverable cost over the decade is mortgage interest, which totals about $971,000 on a $1.6M loan at 6.5%.

One honest caveat. The fractional buyer pays cash, which is why they avoid the mortgage interest that drives the whole owner's cost. But that $500,000 sits in the home instead of earning a return somewhere else. If that cash could grow in the market over the same decade, that's a real opportunity cost this comparison doesn't capture. It's a trade-off every buyer should weigh.

That is the cost-to-memory ratio from where we started. A whole owner buys all 365 nights of the year and carries the whole home to get them. A co-owner buys about 90 nights, roughly the time they would actually use, and splits everything else. Co-ownership lets you pay for the time you will actually use, and that is what makes each memory cost less.

Numbers vary with home price, how much of it you own, and local cost factors. The Year-1 figures assume 1% property tax, 0.35% insurance, 0.35% annual maintenance, home management at 1% of value, 2% closing costs, $12,000 HOA, and $6,000 utilities. The 10-year scenario assumes 20% down on a 30-year mortgage at 6.5% for whole ownership, 4% annual appreciation, 7% selling costs, and operating costs held flat in nominal dollars.

On a Klasma home, a 25% stake in this home is priced at exactly $500,000: a quarter of the home's value, with no premium and no Klasma fee on the sale. What a 25% stake costs, and what Klasma charges walks through the price and the two Klasma fees.
