How to Read a Charleston MLS Listing Like an Agent

Zillow strips out most of the useful data an agent actually reads. Here is what to look for when the full listing is in front of you.

1. Days on market (DOM). Not the same as days on Zillow. MLS days on market includes back-on-market resets after failed contracts. If DOM says 8 but the listing was originally posted 62 days ago, that matters.

2. Original list price vs current price. Multiple price reductions signal either bad pricing at launch or something the market does not like about the home.

3. Seller concessions offered. If a listing offers “buyer to receive $10,000 in seller concessions,” that is a hidden price cut. Great for buyers, telling for what the seller thinks the market is willing to pay.

4. Property tax detail. MLS shows the tax rate assumption. If a listing shows 4 percent tax rate but the current owner is at 6 percent, the buyer will pay more for the first year unless they file legal residence quickly.

5. HOA fees and what they cover. Look for “HOA includes” and check for hidden line items like private street maintenance, pool clubs, marina rights.

6. Flood zone letter. X = low risk, AE = high risk requires flood insurance, VE = coastal high risk requires higher premiums. If it says “unknown” the agent has not done their homework.

7. Elevation certificate present. For coastal properties, this is a big one. A property without an elevation certificate on file is a data gap that can hurt insurance shopping.

8. Age of roof and HVAC. Look for phrases like “roof 2019” or “new HVAC 2023.” Newer systems reduce inspection risk and insurance premiums.

9. Recent updates. MLS listings should specify years for major updates: kitchen, bath, roof, windows. Vague phrasing (“updated throughout”) means you should ask.

10. Showings by appointment only. This can mean the home is tenanted, the seller is difficult, or there is something the seller does not want casual walk-throughs to catch.

11. Contingent status detail. In Charleston MLS: “Active Contingent” often means home sale contingency (soft), “Active Under Contract” means offer accepted but still in due diligence (harder), “Pending” means past due diligence.

12. Agent remarks section (private). Your agent can see private remarks that the public cannot. This often includes seller motivation, timeline pressure, and instructions for showings.
