One door, five doors, twenty doors
Management is priced per door, but the work is not linear and neither is the leverage. The arrangement that is obviously correct on your first short-term rental is usually wrong by your fifth, and the one that is correct at five falls apart at twenty for entirely different reasons. This page walks the same model door up the portfolio curve and marks where each model breaks.
| Per year | 1 door | 5 doors | 20 doors |
|---|---|---|---|
| Gross bookings identical doors, which no real portfolio has | $66,000 | $330,000 | $1,320,000 |
| Full service at 25% | $16,500 | $82,500 | $330,000 |
| Demand-only at 10% plus local ops | $9,600 | $48,000 | $192,000 |
| Per-unit software 3.9% of bookings, $39/mo minimum | $2,574 | $12,870 | $51,480 |
| The gap full service minus software | $13,926 | $69,630 | $278,520 |
| What the gap buys | About 5 hrs/week of your own time | One full-time ops coordinator | A GM, two coordinators, a maintenance tech |
The table repeats one $66,000-gross property, which is a simplification that flatters nobody in particular: real portfolios mix a strong door with two mediocre ones. Use it for the shape of the curve, then rebuild it with your own doors.
Door one: pay the fee or take the evenings
At a single property the fee is small in absolute terms — $16,500 against $2,574 — and the alternative is you, personally, on a Tuesday night. There is no team to build yet and no economies to capture, so the decision is genuinely just a wage calculation: about five hours a week for about $52 an hour.
What matters more at door one is optionality, and it is systematically underweighted. Whatever you sign now determines whether door two is easy or a restart. Two things to protect: a short exit — Grand Welcome states a month-to-month agreement with 30 days' notice, which is the shortest published term among the full-service managers tracked here — and the operating history you are about to create.
The thing that does not scale: operating history in someone else's account
Every full-service, hybrid and demand-only company tracked on this site lists your property under its own platform accounts. Only 5 of the 19 options here leave the listing, the reviews, the Superhost status and the payouts in your name, and all 5 are software you run yourself. On one door that is an annoyance. Across a portfolio it is a structural problem, because review count and response history are the compounding assets in this business and they compound into an account you do not control.
The specifics are worse than the principle. Evolve is the intermediate host, and owners report being unable to see or leave guest reviews or modify reservations; reviews and Superhost status do not come with you when you leave. Grand Welcome's own FAQ says Vrbo reviews can sometimes transfer while Airbnb offers no review-transfer process at all. RedAwning appends "by RedAwning" to listing titles and consolidates properties into a single account feeding 50-plus channels. None of that is hidden — it is simply the deal, and the deal is that you rent the demand rather than build it.
If your plan is five doors in three years, ask what you own at the end of it. A portfolio with five years of reviews under your own account is a materially different asset from five doors that go back to zero the day you change managers.
Doors two to four: the awkward middle
Too many properties to enjoy self-managing, too few to justify staff. This is where most portfolios stall, and the failure is rarely financial — it is that the ad-hoc systems that worked on one door stop working on three:
What breaks
- One cleaner covering three properties on the same Sunday 11am checkout
- No vendor redundancy — one plumber, one handyman, no bench
- Guest messaging that was manageable at one door becoming a second job at three
- Bookkeeping across three properties and three tax jurisdictions
- You are the single point of failure, with no cover for illness or travel
What actually fixes it
- Automated turnover scheduling driven off the booking calendars, not a group chat
- A second and third cleaner on the bench before you need them
- Written check-in, damage and refund policies so decisions stop being bespoke
- One system holding every calendar, not one per property
- A part-time assistant on guest communications — cheap, and it buys back the evenings
Watch pricing shape here, because software pricing is designed around exactly this cliff. Guesty's cheap Lite tier stops at three listings and quotes you for the fourth. Hospitable's per-additional-property increments escalate sharply at the top tier. Hostaway is reported near $40 per listing per month at small portfolios and publishes nothing, so you cannot model it without a sales call. Percentage-based pricing, including TIDY's 3.9%, has the opposite property: it does not step at door four, but it does track your revenue upward.
Door five: the fee gap crosses the cost of a person
At five doors, full service costs $82,500 a year against $12,870 for per-unit software — a gap of $69,630. A fully loaded operations coordinator, salary plus payroll taxes plus benefits, runs somewhere around $65,000. Dividing one by the other puts the crossover at about 4.7 doors.
Somewhere between the fourth and fifth door, you stop choosing between two prices and start choosing between renting someone else's operating team and building your own.
Be honest about what building means. It is payroll, it is hiring and firing, it is covering the coordinator's holiday, and it is the fact that your $67,000 saving is now a person with a mortgage. Plenty of good operators run five doors on full service and sleep well. The point is not that you must insource — it is that at five doors the fee comparison has quietly become an organisational decision, and treating it as a spreadsheet exercise is how people end up with a job they did not apply for.
The multi-market trap
Five doors are rarely five doors in one market. This is where the national brands stop being national. iTrip Vacations, Grand Welcome, Casago and SkyRun are franchise networks: each local office sets its own fee, its own contract terms and its own service standard. Vacasa is now the largest example — Casago acquired it in 2025 and by August 2026 had sold nearly all of the roughly 32,000 units to franchisees and regional operators, so a five-door portfolio spread across five Vacasa markets can be five separate counterparties with five separate agreements.
That is not automatically bad. Local ownership means local accountability, and 89% of former Vacasa field staff were rehired by the franchisees. But it destroys the main reason an investor picks a national brand — one negotiation, one standard, one throat to choke — and it means due diligence has to be repeated per market. Check what your specific office covers before you assume the brand does.
| Company | Where it actually operates | Scale company or third-party figure |
|---|---|---|
| Casago | US and Mexico plus Belize, Costa Rica and the Caribbean through the former Vacasa footprint; 70+ destinations claimed post-merger | 45,000+ claimed immediately after the Vacasa merger; current portfolio not disclosed after the franchise divestitures |
| Grand Welcome | 70+ locations across roughly 22 US states | ~2,000–2,200 vacation homes (company figures vary between pages) |
| Houst | International only — no current US coverage. About 35 cities across 8 countries: UK, Ireland, France, Portugal, UAE, South Africa, Australia and New Zealand. | 11,650+ properties (company figure) |
| iTrip Vacations | ~100–110 destinations across roughly 23 US states plus Hawaii and Puerto Rico | ~4,000+ properties across 100+ locally owned offices (third-party figure) |
| SkyRun Vacation Rentals | Mountain, ski and resort destinations across 15+ US states including Aspen, Breckenridge, Park City, Destin and Maui | ~1,200 homes reported (not company-published; territory counts conflict across sources) |
| Vacasa | Historically hundreds of markets across the US, Canada, Mexico and Belize; now delivered by independent franchisees | ~32,000 units at acquisition; all but roughly 600 sold to franchisees and local operators by mid-2026 |
| VTrips | ~30 resort markets across 10 states, mostly Sun Belt drive-to beach and mountain destinations (AL, FL, GA, HI, MD, NM, NC, SC, TN, TX) | Reported between 4,500 and ~7,000 short-term rentals; sources genuinely conflict |
| Air Concierge | Full local service in ~13 West Coast and Southwest markets (San Diego, LA, Orange County, Bay Area, Palm Springs, Tahoe, Phoenix, Scottsdale, Seattle); the Offsite tier is available nationwide outside those markets | — |
| Awning | Claims all 50 US states on a remote, asset-light model; real-estate brokerage licences listed only in CA, TX, AL, FL, GA, NC and TN | — |
| Evolve | Nationwide US plus some international; properties must pass a qualification screen | 30,000+ properties (company figure, March 2025) |
Houst is in the table as a warning rather than an option: it appears in US-facing lists but operates only internationally, across roughly 35 cities outside the US. Awning and RedAwning are one company — RedAwning acquired Awning in 2024 — so quoting both is not a competitive process.
Twenty doors: you are a management company now
At twenty model doors the portfolio grosses $1,320,000. Full service would cost $330,000; per-unit software costs $51,480. The $278,520 gap funds a general manager, two operations coordinators and a maintenance technician, with change left for tooling. Which is to say: the gap funds precisely the company you were paying 25% to be.
New problems arrive with it. Trust accounting and owner statements matter the moment you take on a door you do not own — and in many states, managing property for other people requires a licence, which is a line investors cross casually and regret formally. Guesty and Hostaway are built for this tier for exactly that reason. Staff scheduling, turnover quality control and vendor contracts become full-time responsibilities rather than weekend admin.
And a percentage of bookings deserves fresh scrutiny at this size. TIDY charges 3.9%, which on a $1.32 million book is $51,480 — real money next to flat per-listing tooling that costs a fraction of it. The counter is that flat channel-manager pricing buys channel management, not turnover orchestration, inspection workflows and maintenance dispatch, so the comparison is only fair if you also price the coordinator who would otherwise do those things. Run both numbers with your own revenue in them; at twenty doors the answer stops being obvious in either direction.
Hybrid setups that hold up
The most useful thing a multi-door operator can internalise is that the management model is a per-door decision, not a per-portfolio one. Four patterns that work in practice:
- Software everywhere, full service on the outlier. Run the cluster you can drive to yourself and hand the ski cabin or the beach house 1,500 miles away to a local specialist — SkyRun in mountain markets, Natural Retreats or Portoro at the luxury end, VTrips across Sun Belt resort towns. You pay 25% on one door instead of all of them.
- Software plus a part-time assistant. Automation handles turnover scheduling and the routine messages; a VA handles the exceptions. Roughly two hours a week of your attention across a small portfolio, and it is the arrangement most operators converge on between doors three and eight.
- Demand-only for the market you cannot crack. If a property genuinely underperforms on distribution, a 10–15% tier from Evolve or RedAwning buys demand while you keep operations. Price the account-ownership cost honestly before you sign — you are renting the demand, not building it.
- Remote coordination where you have vendors but no time. Air Concierge's 12% Offsite tier coordinates cleaners and vendors that you hire and pay, nationwide. The catch is a one-year contract, which is a long lock-in for a remote service.
TIDY is the software layer in patterns one and two above. The per-door framing means you can adopt it on some doors and not others.
Next: the operating responsibility that does not appear in any fee table — permits, licensing and lodging taxes, and which of them a manager will actually own. Or work back through the break-even math on a single door and the full company comparison.
