Medellín's rental market has three doors. Door one — nightly Airbnb — now comes with building inspections, immigration data-matching, and asamblea votes to shut you down. Door three — the traditional unfurnished lease — comes with Colombia's firmly tenant-protective rental law and yields that barely clear inflation. Door two is the one this article is about.
Why the 30-day line is a legal moat
As we covered in the crackdown guide, Colombian law treats accommodation under 30 consecutive days as a tourism service: RNT registration required, building reglamentos empowered to restrict it, enforcement actively hunting violators. Cross the 30-day line and you're in a different legal universe — an ordinary residential tenancy that requires no tourism registration and that a building cannot prohibit through its short-stay rules.
That's the moat. The entire regulatory storm — the fines, the inspections, the 70% reglamento votes — breaks against the 30-day threshold. A furnished apartment rented by the month to a remote worker isn't a loophole; it's simply not the thing being regulated.
30+ day rentals still sit under Colombia's residential tenancy framework (Ley 820), which caps deposits-as-practiced, regulates increases on ongoing leases, and makes evicting a non-paying tenant slow. Mid-term's practical protection is structural: tenants who prepay monthly, stay 1–6 months, and leave on schedule rarely generate the disputes that make Ley 820 scary. Screening — verifiable income, references, deposit or prepayment — is still the job.
The demand side is the real story
A moat around an empty market is worthless. Medellín's mid-term demand is deep and structural:
- Digital nomads and remote workers on tourist entries or nomad visas, staying one to six months, earning in dollars or euros, allergic to hostels and to unfurnished leases requiring a Colombian co-signer.
- Slow-traveling retirees and scouting buyers — including, notably, the people reading this site: the standard advice to rent a month in your target barrio before buying generates a permanent stream of exactly this tenant.
- Professionals and medical-stay visitors — consultants on assignments, patients and families around Medellín's medical cluster, visiting academics.
These tenants pay a furnished premium over local long-term rates because the alternative — signing a 12-month unfurnished lease with local guarantor requirements — is unavailable to them, and 30 nights of even a discounted Airbnb costs more.
The numbers, honestly framed
Rule-of-thumb bands (verify against current listings in your target building — this market has no index):
| Strategy | Gross potential | What eats it | Net reality |
|---|---|---|---|
| Short-term (sub-30-day) | Highest headline — strong nightly rates at good occupancy | Platform fees, cleaning, management 20–30%, vacancy, furnishing wear, RNT compliance, regulatory/vote risk priced at… what, exactly? | Can outperform when legal and well-run; increasingly binary — great or shut down |
| Mid-term (1–6 months furnished) | Commonly ~1.3–1.8× the unfurnished long-term rent for the same unit | Some vacancy between stays, furnishing, utilities+wifi included, lighter management (~10–15% if outsourced) | The strongest risk-adjusted net in most foreigner-relevant buildings |
| Long-term unfurnished | Lowest gross; local-market rents | Little — minimal turnover, tenant pays utilities | Simple, stable, modest; the benchmark the others must beat |
The mid-term case isn't "highest gross" — it's highest gross that survives contact with 2026: no fine exposure, no asamblea veto, monthly turnover instead of nightly churn, and tenants who treat the unit as a home for a season rather than a party venue for a weekend.
Where it works: neighborhood fit
- Laureles — the strategy's capital. Flat, walkable, café-dense, beloved by repeat-visit nomads who've graduated from Poblado tourism. Mid-rise stock with reasonable administración fees keeps the expense line sane. If this strategy has a home barrio, it's here — full context in the Laureles buying guide.
- Envigado & the Estadio/Conquistadores edges — the value versions: slightly lower rents, noticeably lower purchase prices, same tenant pool spillover.
- El Poblado — works, with nuance: enormous demand, but you're paying Poblado prices while amenity-building administración fees bite the net. Best for units bought well, not units bought at the gringo price.
- Belén / Loma de los Bernal — the frontier version: newer towers at lower cost, thinner but growing mid-term demand.
Running it well: the operating notes
- Furnish for a resident, not a tourist. The mid-term tenant's decision drivers: a real desk and chair, fast verified wifi, a functional kitchen, a washing machine, blackout curtains. Instagram wall art converts nobody who's staying 90 days.
- Price monthly, discount for length. A published 1-month rate with visible discounts at 3 and 6 months fills calendars and self-selects longer, lower-churn stays.
- Use a real contract every time. A proper Spanish-language furnished-lease contract with inventory annex, deposit or prepayment terms, and fixed end date — drafted once by a lawyer, reused forever.
- Channel mix: Airbnb/monthly-stay platforms (30-day minimum set), furnished-rental agencies, nomad Facebook/WhatsApp groups, and — the endgame — direct repeat bookings and referrals that cut platform fees to zero.
- Still read the reglamento. Buildings can't use tourism rules against 30+ day leases, but a few reglamentos attempt broader furnished-rental restrictions of contested enforceability — and a hostile administración is a daily tax on your operation regardless of who's legally right. Buy where monthly rentals are already normal.
Financing note: mid-term yields comfortably beat Colombian mortgage rates only rarely — if you're modeling leverage, read the 2026 mortgage state-of-play before assuming the spread works. Most operators here are cash buyers for a reason.
The bottom line
Mid-term isn't a consolation prize for people scared out of Airbnb — in 2026 Medellín it's arguably the strategy the city's actual demand base has been requesting all along: a large, dollar-earning, well-behaved tenant pool that wants exactly what a foreign owner can supply, in a legal lane no asamblea can vote away. The buyers doing this well underwrote it from day one and picked the building accordingly — which is a purchase decision, not a management decision.
