Built by flippers, in Portugal
Made by people doing flips on the ground — each module solves a real problem in the process.
“A OnFlip evitou que eu perdesse mais de 20.000€ num investimento imobiliário que parecia excelente. Em menos de 5 minutos percebi que a rentabilidade real era muito inferior ao esperado. Hoje não analiso nenhum negócio sem passar primeiro pela OnFlip. Simplesmente indispensável.”
Everything that matters in one system
12 integrated modules, organized by the 4 phases of a flip — from sourcing to closing.
Find the deal
OnFlip Radar · Automatic sourcing
Instead of just storing what you paste, the Radar brings you properties: forward portal alerts (Idealista, Imovirtual, Casa Sapo) and each listing arrives extracted, scored for flip potential and ranked by verdict. Promote the good ones in one tap.
Prospecting · Deal Radar v2
Automatic score on 8 dimensions: price/sqm, zone, typology, time on market, baths, area, floor and condition. Senior Pre-Analysis with 21 districts × 81 sub-zones.
Geographic heatmap
See your prospects, leads and target zones on an interactive map. Visual score by color. Filters by state, score and type.
Assess profitability
RUBO Method · Bad vs Good
Pro-grade comparables valuation: separates run-down from renovated properties, removes IQR outliers and computes buy price, sale price, margin and a 0-100 Flip Score.
Valuation · Reliable ROI
Correct IMT (R/AB, AR/SU, all brackets). Stamp duty. Corporate tax 19% or table. Real-estate commission. Sale-price sensitivity in 5 points. Parallel scenarios.
Data Lab · Editable data

Frequent questions.
If yours isn't here, write to suporte@onflip.pt.
Does the Radar bring me properties automatically? Does it scrape the portals?
The Radar does not scrape the sites. It works with the alerts the portals themselves send you: you create saved searches on Idealista/Imovirtual and forward those alerts to your Radar address. OnFlip extracts each listing, scores it for flip potential and ranks it by verdict. You can also paste an alert manually.
