About Milton

A Lifelong New Yorker

Born and raised in Inwood and Washington Heights, my journey into real estate began while working at a nonprofit surrounded by NYC's top developers. Intrigued by the business, I launched my career in Fall 2001 and never looked back. At my former company, I rose to Managing Partner and Principal Broker by excelling in technology, marketing, and exceptional service.

With 1,100+ transactions across residential, commercial, and investment properties in all five boroughs, I joined Keller Williams NYC in 2016 to continue delivering results. A lifelong learner, I use data-driven tools, automation, and cutting-edge technology, from custom property websites to predictive market analysis, to give clients a competitive edge.

Beyond real estate, I'm a proud 2x girl dad, my greatest motivation. When not closing deals, you'll find me cheering for the home team or exploring the world. Hablo Español. I represent NYC buyers and sellers as a bilingual real estate agent, in English and Spanish.

Broker Performance

Owner • Washington Heights

"I was trying to rent out my newly renovated condo in NYC's competitive rental market, and Milton Coste handled everything from start to finish. Milton knows the area inside out and was communicative, knowledgeable, and proactive throughout the entire process. Thanks to his expertise, he found a great tenant within just one week at a strong rental price. I highly recommend Milton to anyone looking for a reliable, professional, and results-driven real estate broker."

Leased in one week

Lucienne G.
Buyer • Manhattan

"Milton helped me purchase my first Manhattan condo, and I can't recommend him highly enough. What could have been a stressful process ended up feeling remarkably smooth. From the initial offer through closing, Milton was responsive, knowledgeable, and always willing to take the time to answer questions and explain the details. I always felt informed and supported, but never pressured. If you're looking for a broker who is knowledgeable, trustworthy, responsive, and genuinely invested in helping his clients succeed, I would absolutely recommend Milton."

What is the difference between a co-op and a condo in NYC?

With a co-op you buy shares in a corporation that owns the building and receive a proprietary lease (the lease that gives you the right to live in your unit), and the building's board must approve you. With a condo you own your unit outright with a deed, and no board approval is required. Co-ops are the larger share of NYC's for-sale apartments, commonly estimated at 70 to 75 percent. They usually have stricter financial requirements and monthly maintenance that includes property taxes, while condos allow more flexible subletting and carry different closing costs.

Co-op vs condo: which fits you

What are typical financial requirements for buying a co-op in NYC?

Co-ops typically require a 20 to 50 percent down payment plus post-closing liquidity (cash you still hold after closing), often equal to one to two years of maintenance. Condos are more flexible, and 10 to 20 percent down is common. For both, lenders review your debt-to-income ratio and credit history. Each building can set its own requirements, so verify them with the listing agent before making an offer.

How long does it take to close on a property in NYC?

A condo or townhouse closes in 30 to 45 days from signed contract when the buyer pays cash, and 45 to 60 days with a mortgage, because the loan commitment letter sets the pace. Co-ops take longer, 60 to 90 days or more. The standard co-op contract allows 30 business days for the loan commitment and 10 business days to submit the board package, and Local Law 58 of 2026 then gives the board 15 days to confirm the application is complete and 45 days to decide, with one 14-day extension.

The NYC closing timeline, step by step

What closing costs should I expect when buying in NYC?

NYC buyer closing costs usually run about 2 to 6 percent of the purchase price, depending on property type and financing. Condo buyers pay for title insurance, the mortgage recording tax if they finance (a New York tax on the loan amount), and the mansion tax on purchases of $1 million or more. Co-op buyers skip title insurance and the mortgage recording tax but still pay the mansion tax at $1 million and up, plus a lien search and board application fees. On resales the seller normally pays the NYC and NYS transfer taxes; on new development condos the sponsor often passes them to the buyer. Both sides need a real estate attorney, which typically costs $3,000 to $4,500.

Buyer closing costs: co-op vs condo

Can I see NYC homes before they hit the market?

Yes. With the RLS Coming Soon status, a listing can be marketed for up to 14 days before it goes active, with photos, details and price, but no showings or negotiations are allowed until it goes live. StreetEasy's own pre-market listings are set up separately by the listing agent, and RLS Coming Soon does not feed them automatically. Milton can flag both kinds for buyers so you can prepare an offer before the listing opens to showings.

How Coming Soon listings work

What is the FARE Act and how does it affect NYC renters?

The FARE Act (Fairness in Apartment Rental Expenses Act) took effect June 11, 2025. It requires that whoever hires a broker, typically the landlord, pays the broker fee. Tenants can no longer be required to pay broker fees on landlord-engaged broker listings, while a broker the tenant hires can still charge the tenant. The FARE Act applies to rentals only, not to buying or selling.

Who pays broker fees under the FARE Act

What is a flip tax in an NYC co-op?

A flip tax is a fee some co-op buildings charge when a unit is sold. It typically ranges from 1 to 3 percent of the sale price, though some buildings calculate it per share. The seller usually pays it, though some buildings assign it to the buyer or split it. On a $1.2 million sale with a 2 percent flip tax, the seller owes $24,000 to the building before taking proceeds. Always verify the building's flip tax policy before making an offer or listing.

The NYC flip tax guide

Do I need a real estate attorney to buy or sell in NYC?

In practice, yes. New York City closings are run by attorneys: the buyer and the seller each hire a licensed real estate attorney who reviews and negotiates the contract, handles due diligence, coordinates with the lender and title company, and attends the closing. Attorney fees in NYC typically run $3,000 to $4,500 per side, and title companies play a smaller role than in states that close through escrow.
