The Fiador Problem
The biggest barrier expats face when renting in Medellín isn't finding an apartment — it's satisfying the fiador requirement. A fiador is a Colombian resident who co-signs your lease and assumes joint liability if you default. The fiador must own debt-free real estate (finca raíz) in the same city.
For a foreigner who just arrived in the country, finding someone who will stake their property on your lease is — understandably — nearly impossible. Here are the three proven alternatives that actually work.
Option 1: CDT (Certificado de Depósito a Término)
A CDT is essentially a fixed-term bank deposit that serves as collateral for your lease. You deposit 5–6 months' rent in a Bancolombia (or other major bank) CDT account, which is frozen for the lease term. If you default, the landlord has recourse to the CDT.
- Amount: Typically 5–6 months' rent (e.g., COP 15,000,000–25,000,000 for a mid-range apartment)
- Interest: CDTs earn ~11–13% annual interest (current Colombian market rates), so your money isn't dead — it's generating returns while serving as collateral
- Requirements: Bancolombia account + cédula de extranjería
- Release: At lease end, the CDT plus earned interest is returned to you
Option 2: Póliza de Arrendamiento (Rental Insurance)
A póliza is an insurance policy that acts as your corporate fiador. Major insurers — SURA, Seguros Mundial, MAPFRE — underwrite the lease and guarantee the landlord against default, utility non-payment, and property damage.
- Coverage: Missed rent, unpaid utilities, administración, property damage, even legal costs for eviction proceedings
- Cost: The insurance premium is traditionally paid by the landlord (often passed to the tenant via slightly higher rent)
- Your cost: The credit study (estudio de crédito) fee — typically COP 100,000–200,000 ($27–$54) — is paid by the prospective tenant
- Requirements for foreigners: Valid visa + cédula de extranjería, 3–6 months of bank statements showing income at 2–3× monthly rent, and often a significant upfront payment (4–6 months' rent collateral) because foreign income is harder for Colombian insurers to verify
Option 3: Prepaying Rent in Advance
The simplest and most direct approach: offer to prepay 3–6 months of rent upfront directly to the landlord. This is most effective when renting directly from an owner (rather than through an inmobiliaria) and bypasses the entire fiador/póliza apparatus.
- Typical offer: 3–6 months paid upfront via bank transfer
- Best for: Direct landlord negotiations found through FincaRaiz, porteros, or Facebook groups
- Protection: Always formalize with a written, notarized lease that specifies the prepaid months. Never prepay without a signed contract.
- Risk: If you prepay and the landlord breaks the contract, recovery requires legal proceedings. Choose established landlords with multiple properties.
Which Option to Choose?
| Factor | CDT | Póliza | Prepay |
|---|---|---|---|
| Capital Required | 5–6 mo rent | 4–6 mo rent | 3–6 mo rent |
| Earns Interest | Yes (~12%/yr) | No | No |
| Accepted by Agencies | Most | All | Direct only |
| Complexity | Medium | High | Low |
| Best For | Expats with capital | Corporate relocations | Direct landlord deals |
Frequently Asked Questions
A fiador is a Colombian resident who co-signs your lease and assumes joint financial liability. They must own debt-free real estate in the same city. For foreigners without local connections, alternatives include CDTs, pólizas de arrendamiento, or prepaying rent.
You need to deposit 5–6 months' rent into a fixed-term account at a Colombian bank. The money earns approximately 11–13% annual interest and is returned with interest when your lease ends. You'll need a Bancolombia account and cédula de extranjería.
For short-term furnished rentals (Airbnb, Casacol, Nomad Barrio), no fiador or póliza is typically needed — the premium is built into the higher price. For 12-month unfurnished leases through agencies, at least one of these three alternatives is virtually always required.
SURA is the most commonly used for expats in Medellín, followed by Seguros Mundial and MAPFRE. All require extensive documentation from foreigners. Working with an inmobiliaria that has established relationships with these insurers simplifies the process.
