Student Housing Underwriting Tool for Purpose-Built Student Accommodation (PBSA)
Underwrite a new PBSA development or a stabilized acquisition with your own numbers, checked only against the hurdles you name, and stress-tested across a Downside, Base and Upside case.
Four steps, all in your browser
Nothing you enter is sent anywhere unless you submit the Request Access form near the bottom of this page. Every calculated figure below comes from arithmetic on the numbers you type in, not a lookup against RAYSolute's own research.
Set up your deal
Country, city, deal type (new development or stabilized acquisition), currency and your bed count by type. Only one city on this page, the labeled illustrative example, carries pre-filled numbers.
Enter your assumptions
Costs, rent, occupancy ramp, operating expenses, financing and your own hurdles. Nothing here is looked up for you; it is arithmetic on what you type.
Get your Go / Conditional Go / No-Go read
Checked only against the hurdles you name yourself, minimum stabilized yield on cost, minimum levered Internal Rate of Return (IRR), and maximum development cost per bed. Never an invented industry benchmark.
Stress-test with sensitivity
See a Downside, Base and Upside case built from your own base numbers, moved by the magnitudes you choose, before you decide anything.

What a full RAYSolute feasibility study adds
This tool is a self-service screening calculator you complete yourself in your browser. It does not do the following, and a RAYSolute feasibility study does.
This tool deliberately does not carry live Purpose-Built Student Accommodation (PBSA) market data for Bengaluru, Delhi NCR, Mumbai, Pune or any other real city; only the labeled illustrative example carries pre-filled numbers.
The engine above runs on the construction, land and operating costs you type in. A feasibility study replaces your estimates with quotes and verified comparables for your specific site.
The India-specific checklist above records your own flags and questions; it does not answer them. A commissioned engagement confirms the applicable Real Estate (Regulation and Development) Act (RERA) status, zoning classification, and Goods and Services Tax (GST) rate for your specific project.
Site visits, interviews with universities, competing operators and prospective residents in your specific catchment. This tool cannot see your site or talk to your market.
A model built to withstand scrutiny from a lender, an investor or a board, with sourced assumptions and a full sensitivity band, carrying RAYSolute's name.
How this tool calculates your numbers
Every formula and simplification below is disclosed so you know exactly what the engine is (and is not) doing.
Engine formulas
- Effective Gross Income (EGI): total beds multiplied by underwritten rent per bed, multiplied by average occupancy for the year, less vacancy and credit loss, plus ancillary income.
- Net Operating Income (NOI): Effective Gross Income (EGI) less operating expenses and the management fee.
- Total project cost (development): land cost plus construction cost plus soft costs plus contingency plus financing costs during construction (assumed on an average 50% drawn debt balance across the construction period).
- Total acquisition cost: purchase price plus purchaser's transaction costs plus your capex plan.
- Yield on cost: stabilized Net Operating Income (NOI) divided by total project cost (development) or total acquisition cost (acquisition, shown as "going-in yield" for Year 1).
- Unlevered and levered Internal Rate of Return (IRR): computed over your stated hold period using a bisection solver on your year-by-year cash flows, your exit capitalization rate, and your exit transaction cost assumption.
- Debt Service Coverage Ratio (DSCR): Net Operating Income (NOI) divided by annual interest expense, at the year your occupancy first reaches its stabilized level. This tool assumes interest-only debt service through the hold period, not an amortizing principal schedule.
- Go / Conditional Go / No-Go: every computed metric is checked only against the hurdles you name yourself; a hurdle missed by more than 10% drives a No-Go, a hurdle missed by 10% or less drives a Conditional Go, and every hurdle met drives a Go. Leaving a hurdle blank skips that check rather than defaulting to a benchmark this tool chose for you.
- Sensitivity: the Downside case moves rent, occupancy, construction cost (development only) and exit capitalization rate together, using either the moderate or severe magnitude you select, plus a one-year delivery delay for a development deal. The Upside case applies only a +10% rent improvement; this tool does not assume favorable moves in occupancy, cost or exit pricing beyond what you enter as your base case.
Common questions before using this tool
Answers below match the FAQPage schema embedded on this page so AI assistants can surface them directly.
Does this tool use RAYSolute's real market data for my city?
No, not yet. This tool carries one clearly labeled illustrative example (Example City), populated with round, invented numbers for demonstration only. Every other city in the dropdown, including Bengaluru, Delhi NCR, Mumbai and Pune, shows Market file not yet available for this city; you can still run the calculator for that city using your own numbers, but nothing is pre-filled or looked up on your behalf.
Is this an investment, lending or board-ready recommendation?
No. Indicative screening only, based entirely on the numbers you enter. This tool does not currently carry RAYSolute's proprietary market data for any live city, only a labeled illustrative example. Investment, lending, or board decisions require a full RAYSolute feasibility study with primary market research.
How is the Go / Conditional Go / No-Go read decided?
Entirely against the hurdles you name yourself, minimum stabilized yield on cost, minimum levered Internal Rate of Return (IRR), and maximum development cost per bed. This tool never applies an industry-standard or RAYSolute-invented hurdle; if you leave a hurdle blank, that check is skipped rather than defaulted to a number we chose for you.
What does this tool assume about debt?
This tool assumes interest-only debt service through the hold period, with the loan balance repaid in full at exit. It does not model an amortizing principal schedule. A full RAYSolute engagement can model amortizing debt, refinancing, and a multi-tranche capital stack if your deal needs it.
Can I underwrite both a new development and a stabilized acquisition here?
Yes. Choose your deal type at the top of the deal ticket and the relevant fields, land and construction costs for a development, or purchase price and in-place rent for an acquisition, appear automatically. The operations, capital structure and hurdle sections are shared across both deal types.
