Cost truth across every trade — from the plot to the sale.
Cost truth from day one – work out purchase price, margin and exit reliably before you buy. New build and retrofit alike, from a single apartment block to a whole portfolio.
60 days of the full platform, free – no credit card, nothing charged automatically · you pay only once a scheme is realised
- Do the maths before you sign. Purchase price, development potential and apartment-block costing in one model – you know whether the deal stacks up before you get to the notary.
- Real contractor prices, not estimates. Your costs are built on real market prices across every trade – which is why “from day one” actually holds.
- One number, from acquisition to exit. Costing, tendering, construction and sale all draw on the same data core – from a single block to a whole portfolio. No spreadsheet breaks.
Built by practitioners: 10 years of retrofit project management plus 30+ years of construction expertise.
One truth for everyone – costing, construction and exit from the same data.
An acquisition case that holds
Residual value and maximum land price derived from real trade-level costing – not from gut feeling.
Scales per residential unit
Apartment-block structure with buildings, cores and units – quantities and costs scale automatically.
The whole lifecycle
Early stage, construction and sale on one data core – no handover gaps between costing, award and exit.
What you won't find anywhere else.
From acquisition through to operation — all six come out of one configuration. That is why costs, dates and the tender always agree.
Three-click feasibility
All the way to the residual land value.
Type in an address. Renaldo pulls the standard land value, cadastral map and development potential, works out the maximum massing — and shows GDV, margin and the highest land price the scheme can carry.
Costing without a quantity take-off
Quantities from the building, prices from the market.
You choose the work item. The quantity comes from your building and room data, the price from real regional contractor rates. No counting windows, no calculating wall areas.
The bill of quantities you never have to write
Straight from the configuration into the tender.
Your configuration becomes a tender-ready bill of quantities across every trade — with long descriptions, quantities and unit prices. From there straight into the local search and the online request.
The bid comparison that shows the gaps too
Every bid measured against your own bill of quantities.
The bids line up next to each other, item by item. What becomes visible is not only who is cheaper — but what the cheapest bid leaves out, and how much money that leaves open.
The construction schedule that writes itself
And everyone involved keeps it current.
The durations come from the same configuration as the costs. If one task slips, the whole plan follows. Firms report from the portal — via link, no account.
From ESG baseline to a costed retrofit
Rating, measure, new class.
Energy class and CO₂ per asset — then cost an upgrade at real prices and see which ESG class comes out of it, and what rent uplift § 559 allows.
From the first appraisal to the last flat sold.
Plot, 3D & feasibility – before you buy.
From plot to return in a single pass: official standard land value (BORIS), cadastral map and development potential (plot ratio, site coverage, storeys) with automatic calculation of maximum gross floor area and residential units – no add-on services required. Define the building automatically as maximum massing, manually, or via IFC import – including a walkable 3D model, georeferenced to the parcel. Feasibility is calculated from real trade costs instead of lump sums and shows GDV, margin and residual value – switchable between sale and letting, financing bridge included. Save and compare scenarios.
- Standard land value (BORIS), cadastral map & development potential (max. GFA/units)
- Walkable 3D building model with sun path & overshadowing
- Feasibility from real costs: GDV, margin, residual value
- Financing bridge (max. loan, DSCR, cash flow) & scenario comparison
Buildings, cores, units – cleanly structured.
Model apartment blocks and whole neighbourhoods: buildings with cores, storeys and residential units, each with its own room schedule. Quantities and costs are derived from that structure and scale automatically with the number of units.
- Building → cores → residential units → room schedule
- Quantities scale per residential unit
- New build and retrofit in the same model
Costing with real contractor prices.
Ready-made bills of quantities across every trade, backed by real contractor and consultant prices and linked directly to the building and room data. Which means a reliable full-cost plan in minutes – funding and financing included.
- Real market prices instead of a spreadsheet guess
- Funding & financing module included
- Quantities derived automatically from the structure
From bill of quantities to award – compare bids objectively.
Tender straight from the finished bill of quantities: local search across the professional network, online request and award in the portal. The AI bid analysis lines the bids up item by item – for an award you can justify.
- Contractor portal + online award
- AI bid comparison item by item
- Export to German tendering software (ORCA, Abbey) or CSV/Excel
Your network of trades – portfolio-wide, not per project.
Keep the contractors and subcontractors who have proven themselves in one central supplier library, and use them across every project in your portfolio. Rate each collaboration in three categories (communication, quality, price fairness), with history and average. For every trade Renaldo suggests your best suppliers; with auto-inclusion they land in matching tenders automatically.
- Three-category rating with history & average
- Usable portfolio-wide · auto-inclusion per trade
- Block list for “don't ask again”
Site supervision that lets nothing slip through.
A construction schedule with phases and milestones, inspection points derived from the configured works, defects with photo and location – all audit-proof. The digital site diary documents every working day defensibly: weather pulled automatically from the German weather service, entries by dictation, and an AI weekly report at the touch of a button. AI invoice checking reconciles every invoice against the bill of quantities and the awarded contracts.
- Construction schedule, dates & inspection points (planned/actual per trade)
- Digital site diary: weather automatically, dictation, AI weekly report
- Defects with photo & location · AI invoice checking against the bill of quantities
From finished asset to sale – out of the same data.
The project produces brochures per residential unit with AI-written marketing copy, a shareable data room for buyers and lenders, and the listing export – including an automatically pre-filled asking price derived from the feasibility appraisal, the rent roll and the standard land value. The financing bridge supplies the figures the bank and the buyer need – without reassembling anything.
- Unit brochure with AI marketing copy & a shareable data room
- Listing export with an automatically pre-filled asking price
- Financing bridge (LTV, DSCR, cash flow)
Holding rather than selling? Operation & letting (tenant management, maintenance, ESG) run through the Renaldo Operate module – addable at any time.
Every asset, figure and phase at a glance.
The portfolio dashboard brings together assets, investment volume, residential units and project status across all your schemes. The project-status timeline shows which phase each project is in – from development through to sale.
- Investment volume, residential units & € per unit
- Project-status timeline per scheme
- Sortable & comparable across the portfolio

Renaldo Developer Scale – billed on project value.
The base fee (Developer Scale) unlocks the platform for unlimited projects and participants. Each project adds a one-off project fee per residential unit – fair, transparent and payable only once the scheme is realised. 60 days free – no credit card.
Developer and Renaldo Operate can be combined – both modules on one organisation at the same time, prices additive.
