Calculate subsidised housing in NRW with precision
No commercial, no office space — subsidised residential development only. Approved rents, repayment grants, land values from BORIS.NRW, construction costs, parking, cash flow and exit for your project in North Rhine-Westphalia.
The calculator, its inputs and the PDF report are German-language, because the NRW subsidy programmes, approved rents and official land values are published in German. There is currently no English interface.
If that is a barrier: we at FOURR are happy to look at your project with you. Send us your figures or your existing appraisal and we will tell you whether the NRW subsidy works for you — and whether we can advise you on the project. Correspondence in English is no problem.
EUR 49 net / quarter or EUR 175 net / year · plus 19 % German VAT where applicable · no setup fee
All figures shown are sample values, not real project data. The interface is German.
Residential only. Everything that matters.
Built by FOURR GmbH in Cologne — specialists in the appraisal of subsidised residential projects in North Rhine-Westphalia.
All NRW subsidy programmes
Subsidy paths A & B, student housing and modernisation — with current NRW terms and a source reference for every assumption.
Land values from BORIS.NRW
Enter the address, pull the official land value and include the official map extract in your report.
Three routes to construction costs

Cash flow, DSCR & exit
Debt service coverage, rent increase headroom and an exit calculation with IRR — reported separately.

Upload an existing PDF appraisal: a guided wizard reads the figures, asks for what is missing, checks the maths and creates a project.

Concrete questions on subsidy modules, costs, rents and financing — every answer is calculated instantly and can be saved as a variant.
Bank-ready PDF report
The export mirrors exactly what you see on screen: diagrams, cost routes, map and conclusion.
