Not sure where to start if you’re thinking about moving? You’re not alone.

Right now, there are actually 4 different housing markets running at once, and each one plays by its own rules.

Cash buyers. Buyers taking out a mortgage. Homeowners feeling reluctant to give up their current low rate. And builders eager to sell their extra inventory.

Which group you fall in can completely change how you should approach your move. But that’s where an agent comes in.

We have the expertise on what to do for your specific situation and the strategies that are going to work for you.

Comment below and tell me which group you’re in. Let's figure out your next move from there.

9 Tillinghast Place, East Hampton

Bring your vision to this three-bedroom, saltbox-style split-level home in East Hampton. With a distinctive layout and an opportunity to renovate and make it your own, this property is ready for its next chapter.

The main level features a living room with a fireplace and new insert, a kitchen, and a primary bedroom suite. Upstairs, two additional bedrooms share a Jack-and-Jill bathroom. A full unfinished basement provides additional space. The roof and skylights were replaced approximately five years ago.

The backyard features a deck, outdoor shower, and an approximately 15-year-old in-ground pool with a vinyl liner and new cover. Its heating system is not currently operational.

The home requires mold remediation and repairs following a burst water pipe that caused damage in the primary bedroom. No standing water remains. The property is being sold with the contents remaining inside.
