Analyzing Short-Term Rental Property Returns

A short-term rental can look irresistible on a spreadsheet: nightly rates that dwarf monthly rent, and a property you can occasionally enjoy yourself. But gross revenue is not income, and the gap between the two is where many first-time hosts are surprised.

This article is a framework for underwriting a short-term rental before you buy. It is built for investors and vacation home buyers who want to understand the real return, not the brochure version.

Step One: Verify the Rules

Before any math, confirm that the property can legally operate as a short-term rental. Municipal regulations vary widely and change over time. Cities may require permits, limit the number of permitted units, restrict rentals in certain zones, cap rental nights, or require the owner to live on site. Homeowner associations and private covenants can add further limits.

Verify the current rules directly with the city and any association, in writing where possible, and have your attorney review them. Never assume that a neighbor operating a rental means your property qualifies.

Step Two: Estimate Occupancy Honestly

Occupancy is the share of available nights that are actually booked. It swings with season, local events, property quality, and pricing. Avoid using a best-month figure as an annual assumption.

A sound approach is to model three cases:

• Conservative: weaker seasons dominate and you discount rates to stay booked.
• Base: a realistic mix of strong and slow periods.
• Optimistic: useful only as an upper bound, never as the plan.

Step Three: Build Net Operating Income

Net operating income (NOI) is revenue minus operating expenses, before financing costs. For short-term rentals, the expense list is longer than for a long-term lease:

1. Platform and payment fees.
2. Cleaning and turnover, including linens and supplies.
3. Utilities, internet, and streaming services, which the host usually pays.
4. Property management, if you do not self-manage.
5. Insurance suited to rental use, which differs from a standard homeowner policy.
6. Maintenance, repairs, and periodic furnishing replacement.
7. Local lodging taxes and permit fees, where applicable.
8. A reserve for vacancy and unexpected costs.

Step Four: Price Management Realistically

Management is either a cost or your time. Professional managers typically charge a share of revenue, and that share should be modeled explicitly. Self-managing saves cash but demands responsiveness, often at inconvenient hours. If you cannot answer a guest message or a late-night lockout, you effectively need a manager.

A Hypothetical Illustration

Suppose a hypothetical property earns a certain gross revenue in a year. After platform fees, cleaning, utilities, management, insurance, taxes, and repairs, the remaining NOI may be a fraction of the headline number. Now compare that NOI to a comparable long-term rental. Sometimes the short-term premium remains attractive; sometimes it shrinks to the point where the extra effort and regulatory risk are not justified.

The comparison that matters is risk-adjusted: a short-term rental depends on a permit that could change, while a lease offers steadier, if lower, income.

Questions Before You Offer

• Is the use permitted today, and how stable is that permission?
• What happens to returns if the permit is not renewed?
• Can the property perform as a conventional rental if needed?
• How does the purchase price compare with the NOI under the conservative case?

A Word on Seasonality and Reserves

Short-term rental income is rarely smooth. Strong months can mask slow ones, and a single repair during a busy season can cost bookings as well as money. Build a cash reserve before you close, and plan for the property to sit empty longer than you hope. Investors who budget for the slow months tend to stay calm when they arrive.
