That list is solid, and the reasoning behind it is exactly right. Those five questions map directly to whether a buyer can build, finance, or insure the parcel. Here is how to prepare a useful answer for each one before the phone rings.
Power
Call the serving utility and ask for a written service availability letter. That document does more work than a verbal "yes, it's available."
Water
Contact your county water and sewer authority to confirm service area. If the answer is a well, pull any existing well records from DHEC's online database. If nothing exists yet, say so plainly.
Septic and perc
DHEC keeps records of issued septic permits and approved perc tests. Search by TMS number. If no test exists, you can disclose that honestly. A buyer who wants to do their own test before closing is common, and that is a conversation for them and their agent to handle.
Road access
Pull your deed and any recorded plats from the county register of deeds. Look for a recorded easement or a deeded right-of-way. "Everybody uses that dirt road" is not legal access. A land attorney can tell you exactly what you have.
Flood
Run the parcel on FEMA's Flood Map Service Center (msc.fema.gov). Screenshot the panel and note the flood zone designation. Buyers and lenders will check this themselves, so having it ready shows competence.
A simple one-page document covering all five points, with source links or copies attached, positions you as a prepared seller. That matters more than you might expect to buyers who have wasted time on unprepared listings.
One more tool worth mentioning: if you are still working out your asking price, LandXchange offers a free Smart Pricing estimate you can run directly from your seller dashboard before you go live.
