Can't Make an Open House?

Milton Coste, Licensed Real Estate Associate Broker, KWNYC

Don't Go to Open Houses Alone

As your buyer's broker, I'll attend open houses with you to spot issues others miss, or I can register you and handle the details.

I'll identify red flags in the unit and building
I know the comps before you walk in
I negotiate on your behalf after the showing
I'll review the offering plan and board package

Prefer a Private Showing?

Skip the open house crowd. I can arrange private viewings at a time that works for you.

Available 7 days a week · Evening and weekend appointments

Buyer Representation Agreement: What You Need to Know

Starting 2025, REBNY requires a written agreement before your broker can show you properties. You can attend open houses on your own without one.
