Who we are

More than
a gestoría

A Valencia firm with its own lawyer on the bar roll, its own accountants and its own builders. Outside parties come in only where the law says they must.

·
One point of accountability The firm owns the result from start to finish — not five separate offices taking turns.
·
The whole picture Residency, tax position and the deal itself are decided together, because each one moves the others.
·
Nothing leaves the office Your papers and your data stay with the firm.

Living in Spain
without the paperwork

Moving country is never one procedure. It is a dozen that depend on each other, and we run them together instead of one crisis at a time.

Business and investors

From incorporation
to a finished building

Corporate, tax and project work sit with the same team. Fewer hand-offs between advisers means fewer things falling through the gaps.

The market

Spain is short of homes

Building runs far below pre-crisis levels while demand holds and prices keep climbing. That gap is the opening for refurbishment and development.

Flat under refurbishment
Strategy 1

Refurbish and sell
20–50 % per project

Buy under market value, refurbish, sell. Capital turns around in a single short cycle.

Timeline6–9 months
Returnthe spread between what you pay and what it sells for
Riskmoderate
The two variables are time on market and build costs. Both are covered by a contingency in the model and a fixed-price contract with the builder.
House under construction
Strategy 2

Build and sell
≈39 % per project

Buy the plot, build the house, sell it finished. A house near the sea ends up costing what a city flat costs.

Timeline8–10 months
Returnland plus build against the price of the finished house
Riskmoderate
Permits and utility connections are what move the dates. Both are built into the schedule and the contingency.

Strategies 3 and 4

Return as income

6–8%
Long lets, three years and up Buy, let, hold while the market rises. Low risk.
15–20%
Holiday lets Fitted out for visitors and managed for occupancy. Moderate risk: the season swings, and the tourist licence has to hold.

With the investor

A project built around you

Alongside the ready-made deals there is a second route: a project put together from scratch for one investor. You set the budget, the district, the type of property and when you want out.

Where the deals come from

The margin is made when you buy

You make the money on the purchase, not on the refurbishment. Which is why sourcing and checks matter more than the finish.

01
Open market Stale listings, inherited shares, forced sales.
02
Public auctions Run by the tax authority, social security and the banks.
03
Checks before committing Land registry, charges, community arrears, cadastre.
04
Bank transfers only Every payment is traceable. No cash.
