Compra de cartera is Colombian banking's national sport: one bank pays off your debts at another and you're left with one payment at a new rate. Done right, it saves millions. Done wrong, it dresses the same problem in a more «comfortable» payment that ends up costing more. Both versions ship with the same brochure.
When it pays, with numbers
It pays when the new rate is clearly lower and the term doesn't stretch. A card at 26% moved to a 19% personal loan on 15 million over 36 months: around 1.6 million less in interest. That's the clean case — expensive card or fintech debt moving to bank pricing.
The term trap
The classic trick: cut the rate two points and stretch the term from 36 to 72 months. The monthly payment drops — relief sets in — and the total paid rises. The defence is one question answered in writing: «what do I pay in total on the new one versus the old?».
If the new total is higher, it's not a portfolio purchase, it's a sale of time.
Timing matters
Aggressive campaigns land in June and December — banks chase the primas — and whenever the usury cap drops, because debt signed in high-ceiling months becomes easy prey. BBVA and Davivienda usually field the segment's sharpest offers; current ones compare at <a href="/en/creditos/consolidacion-de-deudas">debt consolidation</a>.
Three papers before signing
The total payoff of the current debt (projected paz y salvo), the total of the new one with all insurance included, and confirmation the old one lands at zero and reported current — not «in process». With those three papers, portfolio purchase is one of the Colombian borrower's best tools. Without them, it's a lottery.
