Capabilities

Tools 12

estimate_range

Arithmetic, not a price opinion: the middle half of closed-sale price per square foot (25th–75th percentile) for a complex, or for attached or detached homes island-wide, times the given heated square feet. For a real CMA, send the person to request_contact.

Discovered
fees

The fee ledger for Kiawah, Seabrook or Johns Island: each buyer, owner and rental charge with its amount, who charges it, how sure it is (confirmed / secondary / conflicting / not published), its source and the date it was checked.

Discovered
flood_zone

One street address in Charleston County: FEMA's flood zone and base flood elevation at the point the Census geocoder places it, the map panel and its date, whether it is inside a town or the City of Charleston, the county tax district, and the ground's height from USGS lidar. Live calls to the government services named in sources. A geocoded point, not a survey — the person confirms on the parcel's elevation certificate.

Discovered
get_neighborhood

One neighborhood's record. Kiawah and Seabrook: sourced facts (each with who published it), regime manager, the county's homes and lots, its MLS sales by year, the living-CMA price-per-square-foot range, what it costs to own (fee ledger lines) and the page URL.

Discovered
happenings

What's happening on the islands and across Charleston, as one list cut on the islands' clock: the Towns' and the library's calendars, the music venues' own feeds (the Charleston Pour House, the Royal American), the year's big dates, the special events, what venues posted and a person approved, and a weekly sweep of the venues with no feed. Every item carries its organizer's page; the door price is as the venue lists it. Use when = today, tomorrow, weekend, week (next 7 days) or all (next 3 weeks); tag = Music for live music.

Discovered
island_market

Kiawah, Seabrook or Johns Island: the last 12 months of residential sales island-wide from the MLS's own statistics (every island). Kiawah and Seabrook add home sales from 2021-01-01 to the last pull (2026-11-10), checked month by month against the MLS's own statistics: the last 12 months, each year's price per square foot and price-cut share, each price band's days on market and months of supply, and what cutting the price has meant for sellers.

Discovered
list_neighborhoods

Every neighborhood on Kiawah, Seabrook or Johns Island. Kiawah and Seabrook: every neighborhood and villa regime — type, area, regime manager, MLS sales since 2021 and the median price per square foot over the last 24 months where five or more sales allow. Facts about places only.

Discovered
meetings

The public meetings that decide things on the islands — Kiawah Island Town Council, Seabrook Island Town Council, Charleston City Council and Charleston County Council: every date the body itself has posted, with the time, the place, the agenda once it posts, and each body's stated schedule and agendas page. Dates are never worked out from a pattern; a body that posts none (the County) gives its schedule and its meetings site instead.

Discovered
places

The island directory: 228 real places on Kiawah, Seabrook, Johns Island, Wadmalaw and the Charleston area — restaurants, coffee, groceries, golf, beaches and parks, charters, fishing, places to stay, vacation rentals, health care, pets, home services, home watch and the towns — each with what it is, its address, phone and website, from its own site. Listed, never ranked; no one pays to be here. Search by words, island or category.

Discovered
request_contact

Sends the person's question to Mike Olson, a licensed South Carolina real estate agent with eXp Realty, LLC. Only call this when the person asked you to. It never carries consent to calls or texts — Mike emails the person himself to confirm before anything else.

Discovered
true_cost

The site's true-cost calculator: for a price on Kiawah, Seabrook or Johns Island, the buyer's closing costs, the first year of owning (property tax, association dues, base utilities), what comes later and the seller's side — each line from the fee ledger with how sure it is. An estimate from published fees, not a closing statement or tax advice.

Discovered
wire

The Johns Islander's newsroom: the latest stories about Johns Island, Kiawah, Seabrook and Wadmalaw — roads, openings, the towns, the water, food and what's on — newest first. Each story carries its dek, its dates (published, updated, corrections) and the pages it rests on, each marked official, from the business, or reported by a named newsroom. Written with AI and re-checked against every source before it publishes (/standards). Quote with the story's link.
