Thinking about trading into a Mount Pleasant rental or second home without a big tax hit this year? If you own investment property, a 1031 exchange can help you defer federal capital gains taxes when you reinvest in another qualifying property. The process is powerful, but the rules are strict and local details matter in Charleston County. In this guide, you’ll learn the basics, the exact timelines, and what to check in Mount Pleasant before you move forward. Let’s dive in.
What a 1031 exchange is
A 1031 exchange lets you defer federal capital gains tax when you sell real property held for investment or business use and buy another qualifying investment property. The rule comes from Section 1031 of the Internal Revenue Code. Only real property qualifies after the 2017 tax changes. Primary residences do not qualify unless you convert them to investment use and meet IRS holding and intent guidelines.
“Like-kind” is broad for real estate. You can exchange a rental house for a small multifamily, a condominium used for investment, or even vacant investment land. For a clear overview of what qualifies, review the IRS guidance on like-kind exchanges in its real estate tax tips.

The timelines you must hit
Two deadlines control every 1031 exchange. Both use calendar days and there are no extensions.
- The 45-day identification period starts the day you close on the sale of your relinquished property. You must identify your potential replacement property or properties in writing to your Qualified Intermediary.
- The 180-day exchange period is the outside deadline to acquire your replacement property. You must close by day 180 or by the due date of your tax return for the year of sale if that date comes first, including extensions.
Identification rules in brief
The IRS allows three common identification methods. You must follow one of these:
- Three-property rule: Identify up to three properties, any value.
- 200 percent rule: Identify any number of properties as long as their total value is no more than 200 percent of the value of what you sold.
- 95 percent rule: If you identify more than allowed above, you must acquire at least 95 percent of the total value of all properties you identified.
The role of your Qualified Intermediary
A Qualified Intermediary (QI) is a neutral third party that holds your sale proceeds and facilitates the exchange. You cannot take possession of the funds at any point. If you or your agent receives the money, the exchange will fail.
Work only with an experienced, insured QI. The Federation of Exchange Accommodators is the trade group for QIs and a helpful starting point to understand best practices. See the FEA site here: Federation of Exchange Accommodators.
Step-by-step plan and timeline
Use this sequence to keep your exchange on track in the Charleston area.
Pre-sale planning
- Speak with a CPA or tax attorney early to confirm eligibility, timing, and state tax treatment.
- Select and engage your QI before you list the property or sign a contract to sell.
- If you need financing, talk with lenders now so underwriting fits within 180 days.
Step 1: Close on your sale (day 0)
Your QI receives the proceeds at closing. The 45-day identification clock starts now.
Step 2: Identify replacements (by day 45)
Give written identification to your QI that follows one of the IRS identification rules. Be precise and on time. Late or vague identification is not allowed.
Step 3: Close on your purchase (by day 180)
Close on the replacement property within 180 days. The QI will transfer funds directly to the closing so you never touch the exchange proceeds.
Step 4: Report to the IRS
You report the completed exchange on Form 8824 with your federal tax return for the year the exchange closes. Your tax professional will calculate basis carryover, boot, and depreciation details.

Mount Pleasant checks before you identify
Local details can make or break your exchange plan. In Mount Pleasant and Charleston County, review these items up front.
Short-term rental rules and licensing
If you intend to operate a short-term rental, confirm zoning, permitting, business licensing, and any accommodations taxes. Rules differ by neighborhood and can change. You also need to review HOA covenants. Start with the Town of Mount Pleasant’s official site for current ordinances and permits: Town of Mount Pleasant.
South Carolina state tax considerations
South Carolina generally conforms to federal treatment for recognizing gain, but the details can vary by taxpayer. Discuss your situation with your South Carolina CPA and review guidance from the state. Reference: South Carolina Department of Revenue.
Ownership, title, and the same taxpayer rule
The entity or person that sells must be the same taxpayer that buys. For example, if you sell in your individual name, do not plan to buy in an LLC without proper structuring. Coordinate with your title attorney before closing.
Financing and lender timing
Some lenders apply different underwriting for properties bought in a 1031 exchange and may require extra reserves or specific appraisal timing. Get pre-approved early so you can close within 180 days.
Insurance, flood, and coastal costs
Coastal properties may have higher wind and flood insurance premiums. Flood zones, elevation, and building features can affect both availability and cost. These items impact your net return, so size them before you identify a property.
Historic districts and design review
Certain Mount Pleasant and nearby Charleston neighborhoods have historic or design-review overlays. If you plan improvements during an exchange, confirm what you can alter and how long approvals may take.
County-level references
For records, taxes, and county regulations, use the official Charleston County portal: Charleston County Government.
What counts as boot and why it matters
“Boot” is anything you receive that is not like-kind real property. Common examples are cash back at closing or a reduction in your mortgage debt when you trade down in value. Boot is taxable to the extent of your realized gain.
Depreciation recapture is not eliminated by a 1031 exchange. It is deferred and will be recognized when you sell the replacement property if you do not complete another exchange at that time. Your CPA can help you plan for this.
Exchange types to know
Most Mount Pleasant investors use a standard forward exchange. You sell first, then buy within 180 days. Other formats can help in tight markets but require more planning and cost.
- Reverse exchange: You buy the replacement first, then sell the relinquished property. This structure needs a specialized QI and careful financing.
- Improvement exchange: You allocate exchange funds toward improvements during the exchange period. Plan early and expect extra documentation.
Common pitfalls to avoid
- Missing the 45-day identification or 180-day closing deadline. Both are absolute.
- Allowing sale proceeds to flow to you or your agent instead of your QI.
- Mismatching taxpayer names between the sale and the purchase.
- Ignoring town STR rules or HOA restrictions before you identify a property.
- Underestimating QI, legal, lender, insurance, flood, and carrying costs.
Property types that fit locally
Investors in Mount Pleasant often exchange into:
- Single-family rentals in established neighborhoods.
- Small multifamily or duplex properties where available.
- Condominiums and townhomes that permit investment use, subject to HOA rules.
- Vacation or short-term rentals, if allowed by local licensing and zoning.
- Vacant investment land for future development, with careful planning around carrying costs.
Pro tips for a tight market
- Pre-identify more than one property to keep options open within the IRS rules.
- Align lender timelines, inspections, and appraisals with the 180-day window.
- If timing is tight, explore a reverse or improvement exchange with your advisors well before you go under contract.
