Thinking about trading into an Islamorada investment property with a 1031 exchange? You are not alone. The Keys draw investors for lifestyle and income, but the rules here are specialized. If you get the tax timing right yet overlook Islamorada’s vacation rental licensing or flood risk, your numbers can change fast. In this guide, you will learn the federal 1031 basics, the local rules that matter in 33036, and practical strategies to make your next move with confidence. Let’s dive in.
A 1031 exchange lets you defer federal capital gains tax when you sell real property held for investment or business use and buy other like-kind real property. After the 2017 tax law change, 1031 applies only to real property, not personal property. You can review the definition and limits in the IRS’s final regulations on real property under Section 1031. See the IRS’s bulletin on the Tax Cuts and Jobs Act regulations for details on the real property limitation: IRS final regulations on Section 1031 real property.
Two firm deadlines control most exchanges. According to the IRS instructions for Form 8824, you must:
Within the 45-day window, you can use one of three identification methods that the IRS allows: the three-property rule, the 200% rule, or the 95% rule. Learn the timing and identification rules here: IRS instructions for Form 8824.
In a delayed exchange, a neutral third party called a Qualified Intermediary holds the sale proceeds so you do not receive or control the funds. If you have actual or constructive receipt of the cash, your exchange fails for 1031 purposes. The regulations also define who is a “disqualified person,” such as your agent or broker within the past two years. Retain and document your QI before the relinquished closing. See the Treasury regulations for QI and identification rules: 26 CFR 1.1031(k)-1.
If you receive cash or other non-like-kind property, that portion is taxable as “boot.” Your basis generally carries over into the replacement property, adjusted for any boot and costs. Report your exchange on Form 8824 with your tax return for the year of transfer. Review mechanics and reporting in the IRS instructions for Form 8824.
If your plan is short-term rental income, the Village of Islamorada requires a Vacation Rental License and annual registration for transient rentals. Licenses are limited by a cap and assessed-value thresholds, and they are non-transferable. Before you identify a property in your 1031, verify license status, eligibility, and any HOA limits that might restrict rentals. Start with the Village’s page on requirements and the current program framework:
Why this matters for your exchange: a license can affect value, underwriting, and whether the property clearly fits a “held for investment” profile. Confirm eligibility before you commit to your 45-day identification.
Monroe County collects a 5% Tourist Development Tax on transient rentals, in addition to state sales and any county surtaxes. Operators must register, collect, and remit. These taxes often apply to room rate, mandatory fees, and cleaning. Make sure your NOI model reflects the full combined tax burden. See the county’s guide: Monroe County Tourist Development Tax.
Islamorada is coastal and subject to flood and storm surge risk. Check the FEMA Flood Insurance Rate Maps for the address to understand required coverage and likely premiums. Use the FEMA map search to evaluate each candidate property: FEMA Flood Map Service Center. Also review condominium or HOA documents for minimum-stay rules or short-term rental restrictions, even if the Village license allows weekly rentals.
Selling a smaller rental and buying a premium Islamorada property is a common move. Route sale proceeds to your QI, identify within 45 days, and close within 180 days. If your replacement price is higher than your sale price, bring cash or financing to avoid taxable boot. Coordinate debt so your replacement loan is not less than the debt you paid off, which can create mortgage boot. See the reporting and debt considerations in the IRS instructions for Form 8824. Locally, verify vacation rental licensing, flood zone, and insurance quotes early.
You can sell multiple relinquished properties and buy one Islamorada replacement within a single exchange. Timing is the challenge because the 45-day and 180-day clocks start from the first transfer. Early QI engagement and tight escrow coordination are essential. The timing framework is outlined in the IRS instructions for Form 8824.
You can sell one property and buy several Islamorada units using the three-property rule or the 200% or 95% rules. Because Islamorada uses assessed-value thresholds and a cap on transient units, eligible inventory is limited. Build a strong backup list that aligns with the Village licensing rules: Village Vacation Rental License.
If you must secure a rare listing before you sell, a reverse exchange or improvement exchange may work under IRS safe-harbor procedures. These structures add cost and documentation, and they still must meet 45-day and 180-day timing measured from the accommodator’s acquisition. Work with an experienced accommodator and counsel. The IRS timing and reporting framework remains in the Form 8824 instructions.
Tenancy-in-Common and Delaware Statutory Trust structures are often used as replacement property. They can provide access to larger assets, but they change control and liquidity. Confirm that the offering aligns with IRS guidance for 1031 treatment. Review the IRS’s guidance references on fractional interests: IRS guidance references on TIC and DST.
If you want limited personal use at a dwelling unit that you acquire in a 1031, the IRS provides a safe harbor. Over a 24-month period, rent it at fair market at least 14 days in each 12-month period and limit personal use to the greater of 14 days or 10% of rental days in each period. See the safe harbor: Rev. Proc. 2008-16.
Confirm that your selling property was held for investment or business. Gather records of use and depreciation. Review the IRS instructions for Form 8824.
Select a Qualified Intermediary before the sale closes. Verify that the QI is independent and not a disqualified person under the Treasury rules: 26 CFR 1.1031(k)-1.
Vet Islamorada targets early. Check vacation rental license status and eligibility, flood zone and insurance quotes, and any condo or HOA rental restrictions. Use the Village’s resource page: Vacation Rental License, and flood maps at FEMA MSC.
Build your financing plan. If you need to increase price or debt to avoid boot, coordinate loan terms and payoff timing with your QI and lender. See debt and boot reporting in the IRS instructions for Form 8824.
Deliver written identification by Day 45. Use the three-property, 200%, or 95% rule as needed. Ensure delivery to your QI by the deadline. Guidance is in the Form 8824 instructions.
Close by Day 180. The QI should fund your purchase directly. If your tax return due date is earlier, that date controls unless you file an extension. See timing in the IRS instructions for Form 8824.
File Form 8824 with your tax return. Carry over basis and update depreciation schedules as required. Use the IRS instructions for Form 8824.
A 1031 exchange can be a powerful way to step into or scale within Islamorada, but success here requires early planning around licensing, timing, and insurance. When you line up the right QI, confirm local eligibility, and build a strong identification list, you protect both your tax deferral and your projected returns.
