OnFlip Studio · 2D + 3D plans
Draw the property floor plan in the browser — walls, dimensions and automatic area — and view it in 3D. No install, works on iPad. The measured area feeds scenarios and the renovation budget directly.
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.
Quick capture · 1 click
Paste a listing description (Idealista, Imovirtual, Casa Sapo) and we automatically extract type, area, price and condition — the prospect enters your pipeline pre-filled, with points of attention flagged. Saves minutes on every property.
