You do not need to know a price today. You do need to know what has to be sorted out first.
Anyone who wants to sell their home on the Costa Blanca almost always starts with the same question: what is it worth? And then gets a number from a calculator, or from an agent who would like the instruction. That number is usually just wrong enough to hang on to for months.
The real question comes earlier. Are the owners on the same page? Is the paperwork complete? Is that extension in the Registro? Do you know what the buyer withholds at the notary? Those are the things a sale gets stuck on here, and they are exactly the things you can sort out before the first viewing.
That is why this check deliberately gives no price. It tells you where you stand, what is missing and what to do first. The price itself I build at the property, on notarial sale figures from your zone and similar homes I actually know. Free, and then it is on paper.
I am an estate agent, not a tax adviser. Where your sale needs a gestor or a lawyer, the check simply says so. And where it is about the home, the price and the buyers, I am happy to help you myself.
