Fast enough for initial pricing. Rigorous enough for investment committee.
Terra is currently in private beta — access is invitation-only. Request access above, or sign in if you are already a tester. Testers start on a 14-day Pro trial; when it ends your account moves to the free plan and your appraisals are kept.
The rigour of XXX. The familiarity of Excel. In the browser.
Terra is not trying to replace Excel. It replaces the work of building the Excel model — and the errors that come with building it by hand.
Work fast in the Terra app; hand over a clean, professional Excel model. They look different by design — and that difference is the point.
Worked example: how a hand-built residual appraisal double-counts finance and profit →
Enter your assumptions and watch the KPIs, IRRs and totals update instantly; calculate the residual land value at the press of a button, and solve to a target return. Built for speed and clarity while you're thinking about the deal.
Every appraisal exports to a clean Excel model where the KPIs trace through their totals down into the monthly cash flows, and a full record of every assumption is set out on its own sheet tab — exactly what was entered in the Terra web app. The record is a statement of what was used, not a driver: the workbook goes back into Terra when you want to change it. A transparent model your colleagues, lenders and investment committees can follow line by line.
Built by property professionals, for property professionals.
Terra was developed from nearly three decades of real estate investment, development and financial modelling experience, with input from other property professionals — because appraisal software should reflect how deals are actually analysed.
Technology should not replace professional judgement. It should make professional judgement easier to apply.
Every appraisal turns on assumptions only experience can set — rental growth, market rent, void periods, tenant quality, capital expenditure, exit yields, and the probability of a lease renewing. Terra will not make those calls for you.
What it does is give them a disciplined framework: one place to enter them, test them, and see instantly what they mean for value and return — so your judgement is applied, not buried in a spreadsheet.
AI can help research the inputs. Terra structures the appraisal. You make the judgement.
Enter your assumptions into sixteen identical sections for cost and income, so every deal is structured the same way and two appraisals can be compared line for line.
Profit, profit on cost, IRRs and equity multiples — leveraged and unleveraged, and you choose which — sit across the top of the appraisal as you work, so you can see what an assumption is worth before you commit to it.
Set the return you need and Terra solves back to the purchase price that achieves it — then exports the whole appraisal to Excel.
Sixteen identical sections, each with ten identical line items — learn one and you have learned the appraisal. The rest is a click from wherever you are on the page.
The whole appraisal on one screen of collapsible sections — no tabs, modules or wizards between you and the input you want.
Thirty-five to pick from, leveraged and unleveraged side by side, arranged how you like and moving as you type.
Every section, month by month, on screen — without opening Excel or leaving the appraisal.
The purchase price that hits a target profit on cost, IRR, GDV or NDV margin — leveraged or unleveraged — or a limit on your equity.
One or two assumptions varied across a grid, every cell a full re-run, as many KPIs in each cell as you want. Pro.
Up to ten limbs with IRR and multiple hurdles, required amounts and catch-ups — investor and sponsor returns reported as KPIs. Pro.
Ten lease areas, each with three lettings: rent reviews, rent-free, review fees, commissions and voids — not a flat rent.
Warnings appear on screen as you work and travel into the workbook on their own tab.
A two-minute walkthrough — from opening the opportunity to a residual land value you can defend.
When someone challenges a figure, you can show them where it came from. In Terra's Excel model the KPIs, totals and balances are live formulas rather than pasted values, so a question about profit on cost is answered by following it down into the monthly cash flows — not by rebuilding the appraisal to check. It's the browser-based XXX alternative for people who like to see the workings, not just the answer.
“AI can process information.
Only you
can decide what an opportunity is worth.”
Terra does not remove the professional from the process. It removes the unnecessary work around them.
100% of what 90% of property professionals need.
Most appraisal happens at two extremes. Terra is built for the ground in between — without the cost, complexity and implementation burden of an enterprise platform.
Total flexibility — and total responsibility. You build, maintain and debug every model. The errors are not always small ones, and the worst are the ones nobody else can see.
Structured and fast in the browser, with a clean Excel model out the other end — so every appraisal your team produces is built the same way. No one's private spreadsheet, no version that only its author understands, and no spreadsheet to build yourself.
Tools like XXX are the institutional standard — powerful and deep, with the complexity and the learning curve that go with it, priced and scaled for large teams, and tied to the desktop. Terra brings the same discipline without the training, on whatever device you have with you.
Commercial real estate and residential opportunities alike — development schemes and income-producing investments, appraised the same disciplined way. From development and value-add through to institutional and long-income — the same rigour whether you are pricing a site today or underwriting a twenty-year hold.
Price a site while you are standing on it.
Price opportunities and advise with a defensible, consistent method.
Test residual land value and appraise schemes before you commit, and compare sites line for line.
Underwrite acquisitions and model returns for a multitude of sub-asset classes, from a simple investment through to long-income and development opportunities.
Produce transparent valuations clients and lenders can interrogate.
Senior debt now costs more than prime yields, prime property sits at or below the gilt, and the exit yield is not yours to assume — why the appraisal is the decision again.
How finance is treated in a residual appraisal — and why it quietly distorts the equity return calculation.
And it comes back: upload a Terra Excel model into Terra and its assumptions are read straight back in, so you can change them and recalculate without re-entering the appraisal.
