Q3 2026
Charleston Multifamily

Elevated rates are putting pressure on multifamily debt coming due over the next few years. At the same time, the supply pipeline is thinning and absorption is picking up, and that's starting to push rent growth. A and B Class assets trade near a 5.4% cap rate, about 150 bps below borrowing costs, so today's buyers are betting on rent growth, not day-one cash flow.

Q3 2026 — Featured Report

Market Overview

Elevated rates are the story this quarter. A lot of multifamily debt comes due over the next few years, and owners who financed at lower rates will feel that pressure at refinance. Higher debt costs keep pushing sale prices down and C Class cap rates up as pricing readjusts.

The other side of the ledger is getting better. The supply pipeline is thinning, absorption is picking up, and that combination is starting to drive rent growth. A and B Class rents run nearly even on studios and 3-bedroom units, while C Class and mobile home park rents sit well below them at every unit size.

A and B Class cap rates hold near 5.4%, about 150 bps below borrowing costs. Buyers at those prices are betting on rent growth, not day-one cash flow. Mobile home parks are the only class still trading above current interest rates.

Submarket Notes Q3 2026
  • Downtown leads rents at $2,900/unit, with 13.8% vacancy
  • Outlying Dorchester has the highest vacancy at 21.5%, three times the 7.1% submarket median
  • Johns Island pairs the lowest vacancy, 5.0%, with $2,100 rents
  • North Charleston is the most affordable at $1,600/unit
