Tools to assess properties and land
Before you buy or hire a design, run the numbers and confirm what needs confirming. Here are all of FYB's free tools: feasibility simulator, fee calculator, tax-benefits guide, planning-constraints checker, Excel spreadsheets and PDF checklists.
Online tools
No sign-up, no email. Each tool works on its own, right in the browser. Portuguese only.
Feasibility simulator
Mark the property or plot on the map and see whether the investment pays off.
Open toolTax Benefits Guide
Reduced VAT, IMI and IMT exemptions and IRS benefits on rehabilitation — what to confirm before counting on them.
Open toolPlanning Constraints Checker Experimental
Click a point on the map to see if it falls under REN or RAN, and the local plan classification where already confirmed.
Open toolFeasibility simulator and quote request
Mark the property or plot on the map, fill in the figures and see whether the investment pays off. You can then send the request to FYB with the location and the simulation included. The simulator is available in Portuguese only.
- Rehabilitate a property or build on a plot
- Real-time results: investment, estimated profit, margin and maximum purchase price
- The same calculations as the kits' Excel spreadsheets
Kits to download
Buy to Rehabilitate kit
For anyone thinking of buying a property to rehabilitate who wants to know, before buying, whether the numbers work and what condition the building is in. The files are in Portuguese.
Feasibility spreadsheet — Rehabilitation
Calculates the investment, the estimated profit and the maximum purchase price. Choose the level of works (light, medium, deep or reconstruction) and, if you already have a real works quote, use it instead of the reference cost.
DownloadTechnical survey checklist
Walk through the property with the list and mark OK, Attention or Serious for each element: structure, roof, windows and doors, electrical installation, water, drainage and gas, and documents. It includes the warning signs where you should ask for a technical opinion.
DownloadBuy Land kit
For anyone thinking of buying a plot to build on who wants to confirm, before buying, what can be built there and how much to pay for it. The files are in Portuguese.
Feasibility spreadsheet — Land
With the building index from the municipal plan (PDM) and the intended area, it tells you whether the building fits on the plot and calculates the investment, the estimated profit and the maximum price for the land. It also compares the cost of building with the value of an equivalent existing house.
DownloadLand analysis checklist
Walk the plot with the list: location and surroundings, planning framework (PDM), ownership and documents, access and utilities, physical characteristics, hidden risks and costs.
DownloadHow to use the tools
Survey or visit
Walk through the property or plot with the checklist, on paper or on your phone, and photograph anything you mark as Attention or Serious.
Simulate the investment
Use the simulator or the Excel spreadsheet. Replace the example figures with your own and check the reference costs.
Ask for support
If the numbers make sense, ask FYB for a technical survey, a feasibility study, or the design and permits.
Indicative estimate
The spreadsheets and the simulator are decision-support tools and do not replace a construction quote or technical, legal or tax advice. Costs per m², transfer tax (IMT), VAT and fees are indicative values and should be confirmed before deciding on a purchase.
Frequently asked questions
Are the simulator and the Excel spreadsheet results the same?
Yes. The simulator uses the same calculations and default values as the kits' Excel spreadsheets.
Is my data stored on the site?
No. The simulator does not store data on the site's server: the request is only sent by email to FYB if you submit it. The map and address search use OpenStreetMap.
What support can I ask FYB for?
Technical survey, feasibility study, architecture design and specialities, permits and construction. You can ask at the end of the simulator or through the contact form.
How many free tools does FYB have?
Four: the feasibility simulator, the fee calculator, the tax-benefits guide on rehabilitation and the planning-constraints checker (REN, RAN and local plan), plus the two downloadable kits.
