Long Island’s Real Estate Dynamic Duo Launch New Construction Marketplace: Mylestone Home

When real estate agent Frances Lisner and custom home builder Gregg Siper crossed paths, they didn’t just build a relationship—they built a company. With over 30 years of combined experience in luxury homebuilding and real estate, the duo co-founded Mylestone Home, a premium real estate platform that simplifies the process of buying and selling new construction homes—starting with Long Island.

Frances brings a unique perspective to the real estate world. After a successful career in tech and digital media, she stepped away to focus on motherhood. But it wasn’t long before she found herself pulled toward real estate—not just by the market itself, but by a passion for helping others find home and a creative drive to tell the stories behind each one. She quickly became a top agent specializing in new construction homes, and it was in this niche where she met Gregg.

Gregg, a respected name in Long Island luxury construction, has spent over 30 years building bespoke homes with craftsmanship, vision, and integrity. Together, Frances and Gregg identified a critical gap in the housing market: a slow, outdated, and often bloated process that left builders and buyers frustrated.

That’s where Mylestone Home was born.

Mylestone Home is a real estate marketplace on Long Island built exclusively for new construction homes. The platform allows buyers to connect directly with builders, bypassing unnecessary middlemen and inflated costs. Every listing on the site is new construction or land—many never seen on other traditional platforms.

On the site, users can:

• Browse exclusive new construction listings

• Create a free account to get early access to homes before they hit the market

• Connect directly with builders for faster, more transparent communication

• Explore upcoming projects and communities

• Shop smarter, with property presentation that showcases new construction the right way

“Mylestone Home was born out of passion, purpose, and a pinch of ‘there has to be a better way,’” says Frances. “This is a platform that brings transparency to an industry that desperately needs it—giving control back to the people who matter most: the buyers and the builders.”

What also makes Mylestone Home special is the synergy behind the scenes. Frances and Gregg aren’t just co-founders—they’re partners in life. Their dynamic, full of heart and hustle, brings an unmistakable energy to everything they do. Together, they’ve built a business rooted in trust, quality, and forward-thinking innovation.

As the housing market continues to shift, Mylestone Home is leading the charge toward a smarter, more streamlined real estate future.

Whether you're a builder looking to list your next luxury property or a buyer ready to find your dream home without the headache, Mylestone Home is your destination.
