Sell one investment property, buy another, and defer the capital gains taxes — if you respect the clock.
A 1031 exchange is named for Section 1031 of the Internal Revenue Code. In plain English: when you sell real property that you've held for investment or business use and reinvest the proceeds into another like-kind property, the federal capital gains taxes you'd normally owe on the sale are deferred — not forgiven. Your tax basis carries into the new property, and the tax comes due at a future taxable sale unless you exchange again.
Why investors love it: the money that would have gone to taxes stays in the deal, compounding in a larger or better-performing property. Sell a tired rental, roll the full equity into a stronger asset in the San Antonio–Austin corridor, and your portfolio grows on pre-tax dollars.
What qualifies: real property held for productive use in a trade or business, or for investment. What doesn't: your personal residence, and property held primarily for resale — a quick fix-and-flip is dealer property, not exchange property.
| Milestone | When | Notes |
|---|---|---|
| Engage your qualified intermediary | Before the sale closes | The exchange agreement must be in place before closing — a QI cannot be added after the fact. |
| Sale of relinquished property closes | Day 0 | Both clocks start at this closing. Proceeds go directly to the QI. |
| Identify replacement property | Day 45 | Written identification delivered to the QI. Most exchangers use the 3-property rule (identify up to three properties of any value) or the 200% rule (identify more, as long as their combined value doesn't exceed 200% of what you sold). |
| Close on replacement property | Day 180 | Or your tax return due date for the sale year, whichever is earlier. This is the hard finish line. |
⭐ The practical takeaway: by the time your sale closes, you should already know what you want to buy. Smart exchangers build the shopping list first — which is exactly the pipeline work in section 05.
Identification pipeline in the corridor. Before your 45-day clock starts, we build a working list of replacement candidates across San Antonio, San Marcos, New Braunfels, Kyle, and Buda — rentals, small multifamily, and other income properties matched to your exchange equity and return targets, each one pre-screened with the numbers discipline from our Investor Hub.
Timeline discipline. Day 45 and Day 180 get tracked like report dates — with buffer built in for inspections, appraisal, and lender conditions, so a slow week at a title company never becomes a failed exchange.
QI coordination. We work alongside your qualified intermediary, your CPA, and your lender — including DSCR financing where it fits — so every party is working the same clock and the same identification list. Buying the replacement is a purchase like any other we run; the exchange structure around it is your QI's and CPA's craft, and we keep everyone synchronized.
Screening a candidate replacement? Run it through the Rental Property Calculator first — then bring it to your consult and we'll pressure-test it together.
This guide is educational information only — it is not tax, legal, or financial advice, and it is not a substitute for advice about your specific situation. 1031 exchange rules are strict, technical, and fact-specific, and they change. Before you sell, consult a CPA, a real estate attorney, and a qualified intermediary, and have them structure your exchange from the start.
