For non-residents, a “mortgage-first, then offers” approach is mainly a
risk-control mechanism: it reduces the probability that a buyer signs an arras contract with deadlines that financing cannot meet.
A simplified view of the process:
- Mortgage pre-assessment (often ~2–6+ weeks)
You gather documents and complete an affordability review so you can search with realistic constraints. Timing depends heavily on document readiness, complexity (e.g., self-employed income), and bank/internal turnaround times.
- Property search + viewings + screening
Search decisions are tied to the financing strategy (price band, location constraints, property type constraints).
Terms are negotiated with a specific focus on timeline feasibility and risk gating.
- Reservation / arras designed around financing and due diligence
Arras timing and clauses should be consistent with the financing plan (and the time needed for checks).
- Mortgage approval (often ~6–10+ weeks after application)
The formal bank process progresses, including valuation/tasación and underwriting. This can be shorter or longer depending on the bank, the property, valuation scheduling, missing documentation, holidays, and workload.
Deadlines are aligned so the transaction can complete without avoidable deadline stress.
Why this reduces risk: when pre-assessment and timeline planning happen early, you can avoid (or renegotiate) situations where a deposit is paid under terms that assume a mortgage outcome that is not yet secured.
