What Is a Real Estate Agency and What Does It Do?

A real estate agency specializes in brokering, advising on, and executing sales, purchases, leases, and investments. It’s far more than “showing homes”: it blends valuation, marketing, legal review, negotiation, financing and after-sale management. Done right, it delivers legal certainty, time savings, and a better net price for the client.

What a professional agency actually does (end-to-end)

1) Market analysis & pricing.
Study microlocation, comparables, condition, renovation potential and demand to set pricing strategy and go-to-market plan.

2) Asset preparation.
Document check (title, liens, certificates), home staging where relevant, editorial photography/video, floor plans, virtual tours.

3) Marketing & positioning.
Multichannel exposure: private database, international network, portals, press and socials. In prime, targeted off-market campaigns.

4) Buyer qualification.
Filter financial capacity, timing and needs to optimize viewings and protect seller privacy.

5) Professional negotiation.
Mediation, structuring offers/earnest money, contingencies, coordinating inspections and using market data to maximize price and terms.

6) Legal & tax safety.
Work with notaries/attorneys. Verify encumbrances, occupancy, cadastre/records, building reports, energy certificates, HOA, planning. Goal: zero surprises.

7) Financing & closing.
Mortgage advisory, appraisal, insurance. Prepare closing documents and oversee completion, registration and handover.

8) After-sale & asset management.
Utilities transfer, property management for leases, maintenance coordination, insurance, and performance tracking for buy-to-let assets.

Role by operation type

• Selling: pricing, storytelling, viewing plan, negotiation, closing.

• Buying: tailored search (on/off-market), technical analysis, renovation study, negotiation.

• Lettings: tenant scoring, lease & inventories, guarantees, issue handling.

• Investment: cap rate, rent projections, regulatory risk, exit strategy, repositioning (value-add).

• Special assets (masías, luxury, buildings): confidentiality, full heritage file, global marketing, coordinated due diligence.

Local boutique or international network?

• Local/boutique: deep micromarket knowledge.

• International network: access to global demand (prime/second homes).

• Proptech: tech-driven, lower fees, lighter full-service.

What truly matters is the team: verified track record, robust processes, transparency and results.

How to choose your agency (quick checklist)

• Proven experience in your area/segment.

• Written valuation method and marketing plan.

• Transparent fees, exclusivity terms and reporting.

• Quality assets (photos, plans, videos) and strong distribution.

• Legal rigor: who checks what and how risks are mitigated.

• References and comparable deals closed.

Why hire an agency?

To reduce risk, save time, and improve outcomes. In complex transactions, the difference often equals thousands in price, months on market, and, above all, peace of mind.
