Most "cost of living in Medellín" content is written for people deciding whether to move, not for people running an investment thesis. The two overlap more than they first appear to — because Medellín's cost structure is part of what makes the investment case work in the first place.
Why cost of living matters to the investment thesis, not just the lifestyle one
A lower local cost base shows up in several places that actually affect returns: it's part of why rental income from a Medellín property can represent a meaningful yield relative to purchase price even when the headline rent, converted to dollars, looks modest by U.S. or European standards. It's also why running a SAS with local staff or a local office tends to carry lower fixed overhead than an equivalent setup in a higher-cost country — which matters directly to the margin on any business investment made through it.
For anyone pursuing the residency-by-investment route, day-to-day cost of living also determines how comfortably the required 180-day annual presence can be sustained without straining a budget built around income earned elsewhere.
What tends to cost more than people expect
Imported goods, specialty electronics, and anything with significant import duties attached run closer to U.S. pricing than the rest of the cost structure suggests. Private health insurance suited to a foreign resident, while still generally inexpensive by U.S. standards, is a real recurring cost worth budgeting deliberately rather than assuming it's negligible.
What tends to cost less than people expect
Domestic help, local transportation, dining at local (non-foreigner-oriented) restaurants, and general local services typically run well below what an equivalent U.S. or European city would charge — a gap that compounds meaningfully over a multi-year residency or business operation, even if it doesn't show up in a single line item.
The investment takeaway
Cost of living isn't a separate consideration from the property, business, or residency case — it's an input to all three. A rental yield calculation, a SAS's operating margin, and the real annual cost of maintaining investor-visa residency all run through the same underlying cost structure. Model it explicitly rather than treating it as background context.
