The SisterListers at Signature Premier Properties

Danielle and Kim.

Sisters, and Licensed Real Estate Salespersons at Signature Premier Properties in Smithtown.

We are committed to upholding the principles of all applicable Fair Housing Laws. NYS Housing and Anti-Discrimination Notice.

Two sisters

They came to real estate from the two ends of a closing.

Danielle Sandella and Kim Fontanez are sisters, and they sell houses together as The SisterListers at Signature Premier Properties in Smithtown, where they have worked as partners since 2023. Danielle has been licensed since 2012 and lives in Commack, where she has been for twenty-one years. Kim has been licensed since 2018 and has lived in Lindenhurst for forty years.

They came to real estate from the two ends of a closing. Danielle worked in title closings, the paperwork that decides whether a sale can close at all. Kim spent twenty-five years in mortgage lending and underwriting, the part that decides whether a buyer can pay for it. Between them a sale is read from both sides before anyone signs.

Danielle works in American Sign Language as well as English.

How they work

What happens before anyone signs

Read the financing first

Kim spent twenty-five years in mortgage lending and underwriting before real estate. Before a buyer falls for a house, she reads what the lender will actually approve, so the offer that goes in is one that closes.

Check the paperwork before contract

Danielle came to real estate from title closings. Certificates of occupancy, open permits, liens and survey questions get looked at before a contract is signed, not discovered by the buyer's attorney three weeks later.

Handle the problems that come up

When violations turned up on a first-time buyer's house, Kim got the contractor estimates herself and went to the town three times until they were cleared. That is what handling it means here.

Sell and buy on one timeline

A seller who also has to buy cannot sell in March and buy in September. Danielle lists, finds and negotiates the two moves together so nobody is between houses.
