Casmir Mason — Founder & CEO, North Pine Capital
Who writes 1031 Deferred: a Texas commercial real estate operator and sponsor, publishing the math the industry usually keeps behind a form.
Casmir Mason is the founder and CEO of North Pine Capital, a commercial real estate investment firm, and the publisher of 1031 Deferred and its sister site, The Nest Planner, which covers retirement tax strategy.
Casmir has been buying, renovating, and operating investment real estate in Texas since 2017 — the hands-on kind, with contractors, lenders, and closing tables — and built this site because the 1031 decision is usually presented by whoever earns a commission on the answer. The calculators and guides here show the arithmetic first, including the option of simply selling and paying the tax.
Why the math here is free
North Pine Capital is a real estate sponsor. That affiliation is disclosed on every page that needs it, because it is the honest answer to "why does this site exist": educated exchangers make better counterparties. Nothing on this site is an offer of securities, and no tool here requires an email to use.
Editorial standards
Every figure on this site traces to a primary source — the Internal Revenue Code, Treasury regulations, or IRS publications — and the assumptions inside every calculator are documented on the methodology page with a change log. When a number cannot be verified, we say so rather than estimate it. Corrections: contact North Pine Capital.
