What a Gulf feasibility has to carry

Feasibility software is sold globally, and most of it was designed around land, construction and sales. A Gulf project adds items that a model built elsewhere may leave out, and they decide whether a launch funds itself.

These items summarise published practice as of October 2026; confirm the rules for your project with your lawyer.

• The payment plan. Buyers pay a deposit, instalments tied to construction, a payment at handover and sometimes instalments after it. Collections follow the plan, not the sales date.
• Escrow releases. In the UAE and Saudi Arabia, buyers' payments go into a project escrow account and are released against construction progress. Money collected is not money available.
• Licences and approvals. Off-plan sales need registration in the UAE and a licence in Saudi Arabia before marketing starts. The licence date is the real start of the sales curve.
• Land holding costs. In Saudi Arabia, white-land fees can apply to undeveloped urban land while approvals run.
• Islamic finance. Development finance often uses structures such as Istisna'a or Murabaha, with their own drawdown and profit schedules.
• Service charges at handover. They shape what buyers will pay and what investors will rent for.

1. ARGUS EstateMaster and ARGUS Developer

Altus describes ARGUS EstateMaster as an "industry leading property development feasibility, budgeting and cash flow forecasting solution" for projects from land subdivision to build-to-rent, and ARGUS Developer as "a single service for end-to-end management of real estate development projects" that can "Evaluate the residual land value of a development site".

Choose one if you run many projects and want every feasibility in the same format, reviewed the same way, with actuals tracked against the original budget. Check how the payment plan and escrow releases are modelled for a Gulf launch before you standardise on it.

2. TestFit and Hektar

TestFit calls itself a "Real Estate Feasibility Service" and says it can "Get your site planning done 4x faster with generative design". Hektar turns "a site and a brief into buildable massing scenarios with the numbers attached". They answer what a plot can hold, not whether the project pays.

Choose one if the question is massing and yield on a plot before you commit design fees. Enter the plot's own setbacks, heights and coverage; neither describes Gulf planning rules on its site.

3. Excel, still

The decision model is very often an Excel workbook, because the finance team built it, trusts it and can audit it. The risks are familiar: one person understands the model, versions multiply, and a broken link goes unnoticed. Any tool you add should respect that model rather than ask you to rebuild it.

4. Realiste

Realiste works inside your Excel model. Upload the feasibility workbook, up to 40 MB, and change it by typing what you want, for example "move handover six months later and push the 40% handover payments with it". Each change is shown before it is applied, formulas are not overwritten silently, and every step can be undone. It was checked on a synthetic 17-sheet model with about 2 million formulas, 150 properties and 300 tenants.

From your brief and documents it can also return a feasibility or underwriting memo with a live Excel model in which every input shows its source and date and a missing figure is named rather than filled. For Dubai launches, the market evidence can start from our catalogue of 1,068 projects and 938 neighbourhoods; for Abu Dhabi from 111 neighbourhoods; in Saudi Arabia and Qatar it starts from your documents.

Choose it if your model lives in Excel and the bottleneck is changing it quickly and safely, or assembling the evidence it needs. It is not a massing tool and not a portfolio feasibility standard.

5. General assistants

ChatGPT and Claude can explain a residual land value calculation, check a formula or draft the feasibility memo in Arabic and English. They will not know your plan dates or escrow schedule unless you give them the model, and they should never supply market figures.

How to choose

Whatever you choose, test it on a past launch: does it reproduce the month when collections and escrow releases stopped matching?

• Many projects and a finance team: ARGUS EstateMaster or ARGUS Developer as the standard; Realiste for fast changes and evidence on individual deals.
• Early-stage plots: TestFit or Hektar for massing, then a cash-flow model.
• One or two launches a year, model in Excel: keep the Excel model and add Realiste to change it and source its inputs.
