Every serious STR investor needs a pro forma before they make an offer. Most are using outdated spreadsheets that miss half the inputs that actually determine whether a deal works.
Search "STR pro forma template" and you'll find dozens of Google Sheets, Excel files, and downloadable PDFs. Most of them were built by someone who owns one rental and made a spreadsheet that worked for them. The problem is that short-term rental underwriting is a living analysis — it requires current ADR data, local occupancy benchmarks, regulatory risk flags, and financing assumptions that change every quarter. A static template can't do any of that.
This guide covers what a complete STR pro forma template must include, where most templates fall short, and why the most effective approach is a tool that builds the model from the listing data automatically.
A short-term rental pro forma is a projected financial model for a specific property. It translates a listing into a set of numbers your client — or your lender — can evaluate with confidence. Here are the sections every complete template needs:
The most common failure is static revenue assumptions. A spreadsheet that uses a fixed ADR and a fixed occupancy rate is a guess dressed up in a table. Markets shift — what performed at 72% occupancy in 2023 may be running at 58% now due to new supply. A good STR pro forma pulls current market comp data, not assumptions you type in manually.
The second failure is missing regulatory risk. If a market has active STR restrictions or pending legislation, that directly affects projected occupancy and investment timeline. A pro forma that doesn't surface regulatory exposure is incomplete — especially for clients presenting to lenders or partners.
The third failure is single-scenario thinking. A solid STR analysis should model a base case, a conservative case, and a stress case. Occupancy 10 points lower than projected. ADR down 15% in year two. Does the deal still work? That's what separates a real underwrite from a hopeful estimate.
The VaultSTR Pro Forma tool was built to solve every one of these gaps. Paste a Redfin or Realtor.com URL and it pulls the property data automatically: purchase price, beds, baths, taxes, and HOA. It then generates a five-year cash flow model that includes cap rate, cash-on-cash return, IRR, DSCR, break-even occupancy, and estimated cost-segregation tax savings.
ProForma Plus subscribers also get live comparable property data — active STR listings in the same market with real performance numbers — plus market occupancy, ADR, and RevPAR analytics, a regulatory compliance AI that flags permit requirements by jurisdiction, and a winning offer generator that back-calculates the price at which the deal hits your target return.
You can edit every assumption: occupancy, ADR, financing terms, operating costs, and more. Stack multiple deals side-by-side to compare them. Export a branded PDF your clients can present to lenders or partners.
For real estate agents working with STR investor clients, a pro forma is a positioning tool as much as a financial model. Showing up to a buyer consultation with a completed underwrite changes the dynamic. You're no longer just finding properties — you're evaluating them on your client's behalf.
The agents using VaultSTR report that investor clients stop shopping them against other agents once they've seen a branded pro forma. The analysis communicates competence in a way that words in a listing presentation don't.
A downloadable STR pro forma spreadsheet template is a starting point, not a solution. The moment you have to manually research ADR comps, look up regulatory requirements, and build multi-scenario models by hand, you've turned a 10-minute underwrite into a two-hour research project. The VaultSTR Pro Forma automates the inputs, models the scenarios, and produces a client-ready output — free for up to three deals.
Paste a listing URL and VaultSTR generates a complete five-year financial model — cap rate, cash-on-cash return, DSCR, IRR, and a branded PDF you can share with clients and lenders.

What is an STR pro forma?
An STR pro forma is a projected financial model for a short-term rental property. It translates a listing into key return metrics — cap rate, cash-on-cash return, DSCR, and net cash flow — so investors and their agents can evaluate whether a deal meets their return targets before making an offer.
What should be included in a short-term rental pro forma template?
A complete STR pro forma includes revenue projections (ADR, occupancy, gross revenue), operating expenses (management fees, cleaning, taxes, insurance, maintenance), financing inputs (purchase price, loan terms, PITI), and return metrics (NOI, cap rate, cash-on-cash return, IRR, DSCR). It should also model multiple scenarios — base, conservative, and stress — to show how the deal performs under different assumptions.
Why shouldn't I use a free STR spreadsheet template?
Static spreadsheet templates require manual data entry for every assumption, including ADR and occupancy figures that you'd need to research separately. They also miss dynamic inputs like real-time market comps, regulatory risk flags, and multi-scenario modeling. The VaultSTR Pro Forma automates all of this from a single listing URL and is free for up to three deals.
How do I calculate cash-on-cash return for an STR?
Cash-on-cash return equals annual pre-tax cash flow divided by total cash invested. Annual cash flow is gross revenue minus all operating expenses minus annual debt service (mortgage payments). Total cash invested includes your down payment, closing costs, and any upfront setup costs. A strong STR cash-on-cash return is typically 8–15% depending on the market.
What is DSCR in an STR pro forma?
DSCR stands for Debt Service Coverage Ratio. It measures whether the property's rental income covers the mortgage payment. It's calculated as Net Operating Income divided by annual debt service. Most DSCR lenders require a ratio of 1.0 or higher to qualify — meaning the property's income at least covers the debt. A DSCR above 1.25 is considered strong for STR financing.
