How a 7% Interest Rate Impacts a $1M Long Island Home Purchase

Understanding What 7% Really Means for Long Island Buyers

If you’ve been dreaming about buying a $1 million home in Long Island, today’s mortgage rates may make you think twice. A 7% interest rate — once considered sky-high — has become the new normal in 2025. But what does that actually mean for your monthly payment, budget, and buying power? Let’s break it down in simple terms.

Monthly Payments on a $1 Million Home at 7% Interest

To understand the real cost, let’s assume:

• Home Price: $1,000,000
  
  

• Down Payment: 20% ($200,000)
  
  

• Loan Amount: $800,000
  
  

• Interest Rate: 7% (fixed)
  
  

• Loan Term: 30 years
  
  

💡 Monthly Principal & Interest Payment: around $5,320 (before taxes and insurance).

Now, factor in Long Island’s property taxes, which can range from $15,000–$25,000 a year, depending on the neighborhood. That’s an extra $1,250–$2,100 monthly just in taxes — meaning your true monthly housing cost could easily hit $6,500–$7,500.

Comparing to a 4% Interest Rate (Just a Few Years Ago)

If you had purchased the same $1M home when rates were 4%, your monthly principal and interest would have been about $3,820.
That’s roughly $1,500 less per month — or $18,000 more per year — just because of the higher interest rate.

That difference doesn’t just impact your monthly budget. It can also affect:

• How much home you can afford
  
  

• Your debt-to-income ratio (a key factor in loan approval)
  
  

• Your overall buying power in Long Island’s competitive market
  
  

The Long Island Factor — Taxes and Affordability

Long Island isn’t just about big homes; it’s also known for big property taxes. In Nassau County, average annual taxes can reach 2.2% of a home’s value, while Suffolk County is slightly lower.

That means:

• A $1M home in Nassau County could have property taxes of around $22,000–$24,000/year.
  
  

• The same home in Suffolk County might be closer to $17,000–$20,000/year.
  
  

Combined with a 7% interest rate, those taxes can significantly push up your monthly cost and affect your long-term affordability.

How This Impacts Buyers’ Decisions on Long Island

Many homebuyers in Long Island are now:

• Looking for smaller homes or moving farther east (like Riverhead or Manorville) for better value.
  
  

• Considering rate buydowns — where the seller or builder pays to lower your rate temporarily.
  
  

• Exploring adjustable-rate mortgages (ARMs) for initial lower payments.
  
  

• Reevaluating budgets, focusing on overall cost of ownership, not just list price.
  
  

This shift is already visible across Long Island’s housing market, where demand for million-dollar listings is slowing slightly, but entry-level homes are still moving fast.

Can You Still Afford a $1M Long Island Home?

Absolutely — but it depends on your income and financial goals. A good rule of thumb:

• To comfortably afford a $1M home at 7%, you’ll likely need a household income of $220K–$250K+, depending on taxes and debt.
  
  

• With a larger down payment (25%–30%), you can reduce your monthly costs and interest over time.

Local Insights: Where Buyers Are Adjusting Most

• North Shore (Manhasset, Roslyn): High taxes and luxury listings mean fewer buyers are stretching for $1M homes.
  
  

• South Shore (Wantagh, Merrick, Massapequa): Popular with commuters; more buyers opting for $850K–$950K range instead.
  
  

• East End (Riverhead, Hampton Bays): Attracting new buyers looking for space and lower taxes.
  
  

Long Island’s diversity of markets means there’s still opportunity — but being smart about financing is key.

What Smart Buyers Are Doing in 2025

1. Negotiating closing credits from sellers to offset rates.
   
   

2. Shopping lenders aggressively for better terms and temporary buydowns.
   
   

3. Investing in homes below budget to leave room for unexpected costs.
   
   

4. Planning to refinance when rates eventually fall — even by 1%, which could save thousands a year.
   
   

Bottom Line — 7% Doesn’t Mean You’re Locked Out

Yes, a 7% interest rate changes the game — but it doesn’t end it. Buyers who plan strategically, work with knowledgeable Long Island agents, and stay flexible can still make their dream home a reality.

Remember: Real estate is about timing, but it’s also about preparation. If you’re financially ready and have a long-term plan, today’s rate doesn’t have to hold you back.
