A Hamptons home sold for $1.9 million in February 2026. The renovation strategy behind it reveals how coastal luxury markets still generate extraordinary returns.

The Big Picture Blythe Graham-Jones was an advertising executive until 2022. She now buys, renovates, and rents Hamptons properties full-time. Her first project started in 2017 with a $635,000 East Hampton home.

The couple rented it immediately, reinvesting income into upgrades. After reappraisal, they secured a $250,000 HELOC loan for a major renovation. "We refinanced and started paying a higher mortgage, but covered it with higher rental income," Graham-Jones explains.

“"Nowhere is like the Hamptons in terms of the rental income you can make in such a short window"”

Why It Matters The Hamptons offer a unique profitability window. **10-12 prime summer weeks can cover a home's annual holding costs**. In markets like the Berkshires, rates vary 50% seasonally; in the Hamptons, variation exceeds 200%.

Graham-Jones's strategy combines timing and capital management. Her second property, bought in 2020 for $895,000, received $250,000 in renovations and sold in 2022 for $1.55 million. Their portfolio now includes a property valued at $2.3 million after $400,000 in work.

The model depends on three factors: financing access, project management, and local market knowledge. Graham-Jones handles renovations; her husband manages finances. They evaluate each property as potential flip, rental, or long-term hold.

The Bottom Line Watch how investors use HELOCs and refinancing to scale operations. In seasonal markets like the Hamptons, timing between purchase, renovation, and sale determines margins. The next test: whether this strategy holds as interest rates rise.
