How Much Money Do You Need to Buy Your First Home on Long Island?

Buying your first home on Long Island can feel financially overwhelming—especially when you hear that you need a perfect credit score or a 20% down payment.

The truth is that many first-time buyers purchase homes with much less than 20% down. However, the down payment is only one part of the money you may need.

Learn how much money first-time buyers may need to purchase a Long Island home, including down payments, closing costs, and New York assistance programs. 

The Short Answer

The amount needed to buy a home on Long Island depends on the home’s price, mortgage program, taxes, insurance, closing costs, and whether you qualify for down-payment assistance.

Most buyers should prepare for:

Before searching for homes in Bay Shore, Brightwaters, Islip, Babylon, or another Suffolk County community, speak with a qualified lender and real estate professional. They can help you understand what you may realistically afford.

Do First-Time Buyers Need 20% Down?

No. A 20% down payment may help a buyer avoid private mortgage insurance with certain loans, but it is not required for every mortgage.

Depending on eligibility, buyers may qualify for conventional, FHA, VA, or New York State mortgage programs with lower down-payment requirements.

New York’s State of New York Mortgage Agency—commonly called SONYMA—offers programs designed to help qualified first-time buyers overcome some of the financial barriers to homeownership.

SONYMA’s Achieving the Dream program offers qualified buyers a fixed-rate mortgage, financing for eligible property types, and a minimum borrower cash-contribution requirement that can be as low as 1% in certain situations.

Is Down-Payment Assistance Available in New York?

Qualified buyers may have access to SONYMA down-payment and closing-cost assistance.

The DPAL Plus 2026 program may provide eligible buyers with up to $30,000 for a down payment, closing costs, or certain mortgage-insurance expenses. Funding and eligibility requirements apply, and assistance is offered through participating SONYMA lenders while funds remain available.

Programs change, and not every buyer or property will qualify. Always confirm current availability before relying on assistance as part of your homebuying budget.

What Should You Do Before Touring Homes?

Complete these four steps before falling in love with a property:

1. Review Your Finances

Examine your income, credit, monthly debts, savings, and regular expenses. The goal is to understand what monthly payment feels comfortable—not simply the highest amount a lender might approve.

2. Get Preapproved

A mortgage preapproval provides a working price range and shows sellers that you have spoken with a lender.

3. Research Assistance Programs

Ask the lender whether you may qualify for SONYMA, FHA, VA, conventional, or other available first-time homebuyer options.

4. Work With a Local Real Estate Professional

Long Island real estate involves more than the listing price. Property taxes, neighborhood conditions, transportation, insurance, and local market competition can affect your decision.

An experienced local agent can help you compare homes and communities while protecting your interests throughout the buying process.

Frequently Asked Questions

Who is considered a first-time homebuyer in New York?

SONYMA generally considers someone a first-time buyer when they have not owned their primary residence during the previous three years. Certain veterans and buyers purchasing in designated target areas may qualify for exceptions.

Can I buy a Long Island home with limited savings?

Possibly. Your mortgage type, credit, income, debt, property price, and eligibility for assistance will determine your options. A lender must review your complete financial situation.

Should I get preapproved before contacting an agent?

You may contact an agent at any time, but preapproval helps you search within a realistic price range and prepares you to act when the right home becomes available.
