When purchasing a home in Hartsdale for around $680,000 with a 20% down payment and a fixed interest rate of 6.6% for 30 years, the monthly principal and interest payment would be approximately $3,460. Additionally, property taxes and insurance will add to this amount, so first-time homebuyers should keep this figure in mind as they start their journey.

The current home price level in Hartsdale is $677,751 according to Zillow, which has increased by 1.2% over the past year (Zillow, 2026). Compared to prestigious school districts like Scarsdale within Westchester County, Hartsdale is considered relatively affordable given its school district reputation. In simpler terms, with the same budget, you may have to reduce the number of rooms in Scarsdale, but in Hartsdale, you can consider a slightly larger space.

When looking at loan types, there are two main categories. One is the FHA loan, which is government-backed. If your credit score is 580 or higher, you can lower your down payment to 3.5%, and if your score is between 500 and 579, a 10% down payment is required (FHA.com, 2026). The other option is a Conventional loan, which can start at 3% for first-time homebuyers or those with an area median income of 80% or less, though it is usually discussed around the 5% mark. It's also important to remember that if your down payment is less than 20%, you will incur a monthly PMI (private mortgage insurance) fee (NerdWallet, 2026).

Your credit score and DTI, or debt-to-income ratio, are the first items checked during the pre-approval process. While each lender has slightly different criteria, DTI is commonly assessed at 43% to 45% or lower. This includes not only your future principal and interest payments, property taxes, and insurance but also existing debts like credit card bills, car loans, and student loans (mortgage-info.com, 2026). Having pre-approval can provide credibility to sellers when making an offer and help you gauge what price range you can afford. It's also helpful to prepare documents like recent income verification, bank statements, and a credit check consent form to expedite the process.

If you live in New York State, you also need to factor in property taxes. The average effective tax rate in New York State is around 1.60% (propertytaxrates.org, 2026), and Westchester County is among the higher rates. If you're coming from another state, this could be a more significant burden than expected, so it's wise to check in advance.

If saving for a down payment is challenging, consider looking into the New York State Mortgage Agency (SONYMA) assistance programs. The Achieving the Dream program allows low-income first-time homebuyers to access a 3% down payment, and the DPAL down payment assistance loan offers up to $15,000 interest-free, forgiven after 10 years of residency (themortgagereports.com, 2026).

Don't forget about closing costs. These include loan origination fees, title insurance, inspection fees, and are typically between 2% to 5% of the purchase price. This can vary by lender, so be sure to get estimates during your pre-approval consultation.

Finalizing a price with the seller is not the end of the process. An appraisal verifies the loan amount, and a home inspection checks for structural or equipment issues. In Korea, the process often concludes with a property registration and transaction confirmation, but in the U.S., these two steps can lead to renegotiation of the price or even contract cancellation. Understanding this difference can help you avoid surprises during the actual contract process.
