APEX in Tanda Casa: definition and context 2026

APEX (Aportación Previa Extraordinaria — Extraordinary Prior Contribution) is the equivalent of a down payment in the Tanda Casa real-estate self-financing system. It is added upfront and reduces the financed amount, which lowers your monthly payment and accelerates your adjudication (delivery of the property).

How APEX works

APEX is money you contribute to the common fund before or in addition to your monthly payments. Each peso of APEX:

Mandatory vs optional APEX

Adjudication timing by effective APEX

Timing depends on how much APEX you build: more APEX, earlier adjudication; without APEX, by scoring. It counts from the date you complete APEX, not from contract signing, and depends on the group fund. Your advisor tells you the month for your amount and savings.

Effective APEX = initial APEX + annual contributions

Effective APEX is not just what you contribute upfront. Optional annual contributions (1% of property value, paid each December, up to 15 times) add to your effective APEX. Example: 20% initial + 15% accumulated annuals = 35% effective APEX, financed amount drops to 65% of property value.

Example: for a $1,000,000 property at 20% APEX, you deposit $200,000 upfront and finance $800,000.
