We sell analysis, not square metres.

Most agencies on the Costa Blanca earn a commission when a property changes hands. We are paid for advice, so our incentive is the return on your capital. When the analysis says no, we say no, even when it costs us a deal.

For investors with a brief

Opportunities that already passed the numbers.

Every property we publish has been through our investment screen, and most submissions do not make it. Each listing shows its headline financials, with the full model on request.

"Most advisors in this market cannot tell you what you will actually pay. I can, because I spent two decades on the other side of the table."
Sarah Katerina Kastlunger PérezCEO, Costa Larga Investment

How we analyse

Five steps, in this order, for every asset.

  1. Market and location screen

    Tourism flows, occupancy depth, supply pipeline and price dynamics for the specific micro-location. Not the region, the street.

  2. Asset due diligence

    Title, tourist licence and its transferability, community charges, condition, zoning and encumbrances, verified before any number is modelled.

  3. Financial model

    All-in cost, seasonal rates and occupancy, a full operating cost schedule, non-resident tax, net yield, IRR and payback.

  4. Strategy

    Short-term, mid-term, redevelopment, hold and resell, or commercial use: what the asset supports, not what the seller wants.

  5. Decision report

    A structured PDF in two business days, with a clear yes or no.

  6. What you receive

    The same model we use to screen our own listings.

    • Total investment and equity
    • Levered IRR and multiple
    • Year-one NOI and cap rate
    • Cash-on-cash by year
    • Debt coverage, break-even
    • Real returns after inflation

Our experience

Built from inside the Spanish tax system.

Our co-founder spent 20 years as a Senior Director at SUMA Gestión Tributaria, the tax authority of the Province of Alicante. From inside, the same problems came up across thousands of transactions: unpaid property taxes tied to the title, undeclared extensions that turned into fines, tourist licences that could not pass to a new owner, community debts waiting for the next buyer.

None of it appears in a listing. All of it appears in our reports.
