How to evaluate a short-term rental before you buy

A short-term rental ('STR') is a small operating business attached to a house, and buying one is buying the business, not just the address. So the question that decides everything is not whether you love the property. It is whether this specific house, in this specific market, at this specific price, can carry itself. I answer that question the same way every time, in three ordered stages: a $250 Feasibility Screen, a $500 Full Deal Underwriting, and a $400 Market & Property Analysis when the market itself is the open question. The evaluation ends in a written go/no-go and a bid number you can defend to a lender, a partner, or yourself.

The enemy of a clean purchase is rosy projections meant to talk you into a deal. A revenue estimate built on peak-season occupancy, a spreadsheet that skips reserves, a screenshot of one comp's best month: those numbers exist to close a sale, not to protect your capital. Buy on them and you are buying on hope. Reality first. The local rules, the season, the competition, and the house itself come before any projection.

One boundary before the method. Everything below is advisory work: a best-effort desktop assessment of the economics and posture of a deal. It is not legal, tax, accounting, or inspection advice, it does not confirm that STR use is permitted at the address, and I do not file permits or represent you as a broker. You confirm compliance, insurance, and inspections with the right professionals before you close. What I bring is the operator's read, so you decide with numbers instead of a feeling.

Why buying on hope costs you

Start with what the bad default actually costs. A projection built on the best month of the best comp does two things: it inflates the price you are willing to offer, and it hides the floor you will actually live on. You overpay on day one, and you meet the real economics in month three, when the slow season arrives and the mortgage does not. The money is gone at closing. The months go to fixing a purchase that a written evaluation would have re-priced or killed for $250.

The second layer is quieter. Even a good property buries a capable owner in decisions: pricing, calendar rules, promotions, and platform settings never stay 'done.' Walk in without a clear read on the market and the house, and every one of those decisions gets made from confusion. A confused owner overpays, freezes, or gets burned. The evaluation exists to remove that confusion before the wire, not after.

This method is not theory. I have launched and run STRs across several markets, including years managing hundreds of units in Colorado Springs, and I operate furnished rentals in the New York metro today: 237 STRs operated, 16,100+ reservations, 23 markets across 7 states. The three stages below are what that experience boils down to when capital is about to move.

The method, in order

We do this in order. The point isn't to do more, it's to get each decision right and move to the next. The order is also the money logic: the cheapest test runs first, so the expensive analysis is only spent on properties that earned it. A $250 screen that kills a property is not a failed step. It is the step doing its job, for less than the cost of the inspection you would have paid for later.

1. Feasibility Screen: $250 per property, two business days. A written kill-or-advance decision covering STR zoning posture, suitability, red-flag detection, and operator feasibility, plus a call up to 15 minutes.
2. Full Deal Underwriting: $500 per property, five business days. A written memo with matched comps, a conservative pro forma with reserves, three scenarios, and a go/no-go with bid guidance, plus a call up to 30 minutes.
3. Market & Property Analysis: $400 per market or per address. A written read on demand steadiness, seasonality, regulatory risk, property-type performance, and realistic rates and occupancy.

One sequencing note. If you already know your market (you live there, you have watched its seasons, you know its rules), the screen and the underwrite are usually enough. If you are choosing between two or three markets, run the market analysis first, at $400 per market, before you fall in love with an address in the wrong one. The stages are ordered by commitment, not by the calendar.

Stage 1: the Feasibility Screen, $250 and two business days

The screen is a kill-or-advance filter. You bring me an address, and within two business days you get a short written screen and a call up to 15 minutes with a clear answer: this property is worth underwriting, or it is not, and here is why. The fee is $250 per property, and I cap the work at four screens a week so each one gets a real look instead of a template pass.

Four things get checked. First, STR zoning posture: how the town appears to treat short-term rentals, read from the desk, best effort. Second, suitability: whether this house, as a product, fits what guests in that market actually book. Third, red-flag detection: the deal-killers that hide in plain sight. Fourth, operator feasibility: septic, water, heating, power, internet, access, and seasonality. A cabin guests cannot reach in February, or a septic system that cannot handle a full house, fails no matter what the revenue projection says.

Operator feasibility gets the extra sentence because it is the check most buyers skip. You are the one who will run this property day to day, and a house you cannot realistically operate is not a deal at any price. The screen is built to surface that before you spend $500 on underwriting or six figures on the house. I break down exactly what the screen covers, and what a desktop screen cannot promise, in the feasibility check guide.

Stage 2: Full Deal Underwriting, $500 and five business days

Properties that survive the screen earn the full underwrite. It starts with comp alignment: listings that genuinely match the property on market, bedroom count, quality, and guest experience, and what they actually charge and fill through the seasons. From those comps comes a realistic revenue range, not one flattering number, because rate and occupancy move with the calendar and the competition. If the honest range does not clear the costs, that is a finding, and you want it now, not after closing.

The range then becomes a conservative operating pro forma. True costs go in: cleaning, supplies, platform and processing fees, utilities, software, insurance, maintenance. Reserves go in too, because turnover, repairs, and slow stretches are part of the business, not exceptions to it. I underwrite the floor. The question is not whether the property makes money in a peak year. It is whether it survives a soft one and still covers its debt.

Then the pro forma runs three ways: conservative, base, and aggressive. Three scenarios show you where the risk actually sits. A deal that only works in the aggressive case is fragile, and I will say so plainly. A deal that clears its costs in the conservative case has real margin, and the memo shows exactly how much.

The deliverable is a written underwriting memo plus a call up to 30 minutes: a go/no-go and, when it is a go, bid guidance, the price at which the numbers still work and the line past which you walk. Turnaround is five business days, and I take at most two full underwrites a week. If you go on to build the property out with me, up to $1,000 of these advisory fees credits toward the build-out. The full method, step by step, is in the underwriting guide.

Stage 3: Market & Property Analysis, $400 per market or address

Sometimes the property is not the question, the market is. The market analysis, $400 per market, is a written read on the things a listing screenshot never shows: how steady demand actually is, how hard the seasonality swings, where the regulatory risk sits, which property types perform there, and what rates and occupancy are realistic rather than advertised. If you are weighing an established market against a town you visited once on vacation, this is the $400 that settles it.

The property version, $400 per address, goes the other direction: comps for the specific house, a realistic rate and occupancy read, and the full cost-and-income picture run at conservative, base, and best cases. It ends in one of three calls: go for it, renegotiate, or walk. That third option is not a consolation prize. Walking away from a bad address for $400 is one of the best returns in this business.

Half of what you spend on these reports credits toward a build-out if you move forward, so the analysis is not money spent twice. And if the market question is where you are stuck right now, start with the market guide, which walks through how I judge whether a market is good for STR at all.

What a defensible go/no-go looks like

Defensible means written, numbered, and assumption-labeled. At the end of this method you hold a document that states the decision, the revenue range it rests on, the costs and reserves behind it, the three scenarios around it, and the bid at which it all still works. You can hand it to a lender, a partner, or a spouse and walk them through why. You know your walk-away line before the negotiation gets emotional, which is exactly when you will need it.

And a no is a result, not a failure. A kill at the screen costs $250. A no after full underwriting costs $650. Compare that to what the rosy projection was selling: an overpaid closing, a peak-season pro forma meeting an off-season calendar, and months of fixing a property you should have re-priced or passed on. The cheapest problems in this business are the ones you find before you own them.

No guarantees, stated plainly. I do not promise any particular bookings, revenue, occupancy, rate, ranking, reviews, or return. Performance depends on seasonality, demand, competition, platform algorithms, property condition, reviews, and how the property is run, and those sit outside my control. This evaluation improves the quality of your decision. It does not remove the risk of the deal.

What the full evaluation costs, and what happens next

The math on the whole method: $250 for the screen, $500 for the underwrite on a property that advances, $650 total per serious candidate. Add $400 per market if the market itself is in question. Against a six-figure purchase and a mortgage that does not care about your projections, that is cheap insurance. And the fees roll forward: up to $1,000 of screen and underwriting fees, plus half of any report spend, credits toward a done-for-you build-out (the Design, Setup and Launch Blueprint, starting at $3,000) if the answer is go.

The next step is deliberately small. Send me the address. In two business days you get a written kill-or-advance answer and 15 minutes on a call to talk it through, for $250. If the property earns it, we underwrite. If it does not, you just saved yourself the most expensive kind of tuition, and we look at the next one.
