Case Study: CRH’s Haunted Duplex Flip

Project Overview

Snapshot: Bought for $600,000, put in $162,000, sold for $990,000 in 7 months.

This one earned its name: the Haunted Flip. Despite strong underwriting, spooky, unforeseen issues kept popping up—communication misses, scope creep, a failed first contract, and relist drag. This is a lesson-first case study.

  • Location: Charleston, SC

  • Timeline: 6 months (Start: May 2025 • Finish: October 2025)

  • Objective: Purchase, renovate, and sell a duplex for maximum ROI


Step 1: Acquisition

Finding the Right Property (MLS)

There are still deals on the MLS—you just need to make offers and know what to look for.

Charleston Revival’s “What We Filter For” Checklist:

  • Multiple price drops

  • Extended days on market

  • Back on market

  • Temporarily off-market

  • Expired listings

  • FSBO

  • Plus: “no mortgage” property after prospecting

Purchase Price: $600,000
Key considerations: Location, structural integrity, neighborhood comps, duplex layout efficiency, and exit scenarios.

Step 2: Renovation Strategy

Planning for ROI (and Handling Surprises)

Full reno across both units. Then the hauntings:

  • Added $15,000 to fix a supposedly “new” roof

  • Electrical & plumbing swung over budget

  • Fencing became an unaccounted cost after the major scope

  • Coordination gaps between GC and subs caused rework and delays

Scope highlights:

  • Kitchens + bathrooms modernized (both units)

  • Open-concept living where feasible

  • Energy-efficient windows/appliances

  • Fresh exterior paint, landscaping, and new fencing for clean access lines

Total Renovation Cost: $162,000

Step 3: The Sale

Marketing & Closing (Momentum Matters)

  • Listed at $1.1M, which represented max ARV based on comps and price per square foot. In hindsight, we should’ve trusted our gut and listed 3–5% below max ARV for a faster sale and smoother close.

  • Initial contract fell through due to GC misrepair/miscommunication

  • Back on market → momentum loss

  • Fence/survey discrepancy slowed traction

  • Closed at $990,000 with $35,000 in seller credits


What Haunted Us (and What We Learned)

1) Pricing Hubris Hurts.
Stretch-listing above duplex comps cost momentum. Price to the market you have, not the one you want.

2) Communication ≈ Cost Control.
Most budget blowups trace back to unclear direction or missed accountability between GC ↔ subs. Write it down. Timestamp it. Confirm it.

3) Plan for Phantom Costs.
“New” roof? Still needed $15K. Fencing, grading, and legacy MEP issues materialize post-demo. Carry a contingency that’s real, not aspirational.

4) MLS Is Still a Gold Mine.
No-cost acquisition channels (MLS) work when you filter hard and move decisively: multiple drops, DOM, BOM/TOM, expired, FSBO, and “no mortgage” flags.

5) Momentum Is a Moat.
Once you relist, you’re fighting uphill. Reposition quickly (price, narrative, photography, issue resolution) or bleed time and finance costs.

Key Takeaways

  • Smart Acquisition: MLS listings are no-cost acquisitions if you filter aggressively and make disciplined offers.

  • Focused Renovations: Invest in quality general contractors and document everything to avoid rework.

  • Efficient Execution: Timelines and budgets matter—track both closely and assume surprises.

  • Marketing Matters: Duplex-listing best practices and realistic pricing protect momentum and widen buyer interest.
