CASTEL INTELLIGENCE

We find underpriced houses and work out what they could become.

We take a real house from the open market, check the price, the paperwork and the building rules — then cost out three scenarios: refresh it, rebuild it, or resell it fast. Each with a budget and a timeline.

01

We sell nothing

We are not an agency: we check the house and run the numbers. The deal is yours.

02

Three scenarios with numbers

Every house gets three plans: refresh, rebuild or fast resale — each with a budget, a timeline and a profit estimate.

03

Checks before money

Building rules, what actually sold nearby, and the state of the house itself — all verified before you spend a euro.

OUR CASES

Houses we have broken down.

Every house goes through the same checks: price against the market, building rules, three scenarios, risks.

Our rules

  1. 01Every number carries a date and a source.
  2. 02We calculate with a margin for error and never promise profit.
  3. 03The site shows the area only; the exact address and documents come up in a private conversation.

An independent break-down for discussion — not a call to buy and not a guarantee of income.
