Buying a home in Mount Pleasant is exciting, but the due diligence period in South Carolina can feel like a high-stakes countdown. You want to know exactly what to check, when to act, and how to protect your money. In this guide, you will learn what the due diligence period means in South Carolina, how to set the right timeline, which inspections matter most in our coastal market, and how to negotiate with confidence. Let’s dive in.
South Carolina due diligence at a glance
The Due Diligence Period is a negotiated window that begins once your offer is accepted. During this time, you can investigate the property and terminate the contract for any reason. It is separate from appraisal, loan, and closing timelines, which means you must track each deadline carefully.
Because this window gives you broad rights, it is one of the most important parts of your offer strategy. It balances buyer protection with the seller’s need for certainty. Your agent can help you set a timeline that fits your goals and the property’s complexity.
Due diligence fee vs. earnest money
- Due diligence fee: A negotiated, typically nonrefundable payment made directly to the seller at acceptance. It compensates the seller for taking the home off the market while you inspect.
- Earnest money: A deposit held by the closing attorney or title company. If you terminate properly within the due diligence period, you can generally recover earnest money. If you close, both the due diligence fee and earnest money are usually applied to the purchase price.
- Practical takeaway: the due diligence fee is a calculated risk. You gain flexibility to walk away, but the seller keeps this fee if you terminate.
How long should your DDP be
Common lengths range from 7 to 14 days for in-town conventional purchases. Relocating buyers, second homes, new construction, or complex properties often need 14 to 21 days. In hot seller markets, sellers may push for shorter periods or a larger due diligence fee.
If you are local and can schedule inspections immediately, 7 to 14 days can work. If you are buying from out of town or want multiple specialty inspections, ask for 14 days or more and be ready to offer a stronger due diligence fee.
How the DDP interacts with appraisal and loan
Your lender’s appraisal and underwriting follow their own timelines. Appraisals often occur during the due diligence window, but appraisal issues can still affect the loan even if your DDP has ended. Build in time to discover anything that could affect financing, such as structural concerns or flood insurance issues.
What to do during the DDP
Your goal is simple. Confirm the property is sound, insurable, and aligned with your plans. In Mount Pleasant and greater Charleston, coastal conditions and flood exposure make a thorough plan essential.

- Mold and moisture assessment, with thermal imaging if needed
- Roof, attic, and exterior envelope review for wind and hurricane wear
- Flood risk check and elevation certificate review if in a flood zone
- Sewer or septic evaluation and lateral scope, plus confirmation of public sewer connection

- HOA documents review for rules, fees, reserves, and any special assessments
- Permitting and renovation history for major work or additions

When to add specialists
- Structural engineer if you see foundation settlement or significant structural issues
- Roofing specialist if the roof is older or shows deterioration
- Coastal and shoreline review for waterfront properties
- Environmental inspection for properties with past commercial use
- Wind mitigation inspection if you want potential insurance discounts
Documents to request and review
- Seller’s Property Condition Disclosure
- Existing survey and recorded plat
- HOA resale package, bylaws, and rules
- Permit and certificate of occupancy history for major alterations
- Title commitment and related exceptions
- Any recent inspection reports or repair invoices the seller provides
- Insurance quotes that reflect the property’s true flood and wind profile
Timing and sequencing tips
- Schedule the general home inspection within 24 to 48 hours of ratification.
- Use that report to trigger specialty inspections, like structural or mold.
- Request HOA documents right away. Some packages take several days.
- Start insurance checks early, especially if the home sits in a flood zone or near tidal areas.
Negotiation and termination checkpoints
Inspection results are your roadmap. You can request repairs, a closing credit, or a price adjustment. The seller can agree, counter, or decline. Any agreement must be captured in a signed amendment before the deadline.
All notices must be in writing and delivered the way your contract requires. If you plan to terminate, send the formal notice before the due diligence period expires. If you miss the deadline, your termination rights under due diligence are generally lost and your earnest money can be at risk if you later default.
Credits can simplify things for the seller. Repairs may be better for you if a system is critical to function or safety. If a lender flags a safety concern, underwriting may require repairs regardless of your preference.
Pitfalls to avoid
- Missing the due diligence expiration or relying on verbal promises
- Confusing the due diligence fee with earnest money and losing leverage
- Waiting to verify insurability for flood or wind coverage
- Delaying the general inspection and running out of time for specialists
Mount Pleasant specifics to watch
Mount Pleasant spans multiple FEMA flood zones. Requirements and premiums vary. Elevation certificates and mitigation measures can influence cost and eligibility, so verify your flood zone and get quotes early in the process.
Coastal climate brings high humidity, salt air, and periodic storm exposure. Inspect for corrosion, wood rot, and roof wear. A focused look at the exterior envelope, flashing, and attic ventilation goes a long way.
Termites and other wood-boring pests are common here. A termite inspection is standard in South Carolina transactions. Ask about any active treatment plans or transferable warranties.
Many neighborhoods have HOAs. Review the resale package for assessments, reserve health, insurance obligations, and rental rules if you are buying a second home. Also check local permitting history, especially for older homes or those near historic areas.
Confirm whether the home is on public sewer or a septic system. Septic systems need proper inspection and can limit future additions. For newer builds, confirm compliance with current coastal wind standards. Older homes may need upgrades that matter to lenders and insurers.
