The Real Measure of Affordability Isn’t the Price of the House

Homebuyers in coastal real estate markets are increasingly at risk of misjudging what they can genuinely afford. According to Lorraine Weber, a Long Island realtor specializing in post-Hurricane Sandy communities, many buyers focus on negotiating the lowest purchase price while overlooking the factors that actually determine their monthly housing costs. This oversight, she says, can lead to unexpected financial strain after closing.

Weber, a realtor with Coldwell Banker American Homes, points out that in coastal areas, flood insurance, property taxes, and access to specialized mortgage programs can raise or lower monthly payments far more than the sale price alone. “The biggest factor for any buyer is their monthly payment, what they’re actually paying for the house monthly, not what price they bought the house for,” Weber explains.

This focus on monthly payment has become more urgent as costs outside the sale price continue to rise. In many coastal regions, insurance requirements and tax rates vary block by block, creating hidden costs that surprise buyers after closing. Weber emphasizes that buyers must evaluate all recurring expenses, insurance, taxes, and mortgage terms, rather than just the initial price. “When you factor in insurances and flood insurance and taxes, that’s all part of your monthly payment,” she notes.

The Post-Sandy Insurance Landscape

Long Island’s South Shore offers a clear example of how insurance costs can reshape affordability. More than a decade after Hurricane Sandy, the area’s insurance rules and building codes have changed dramatically. FEMA redrew flood zones; building codes now require elevated construction above the base flood elevation; and insurance premiums have become highly variable.

According to Weber, these changes have created a patchwork of insurance costs even within the same neighborhood. Some homeowners are “grandfathered” into lower flood insurance rates because of when their policies were written, even if their properties are now classified as higher-risk zones. Others face much higher premiums if their homes were built or renovated after the new rules took effect.

This means that two nearly identical homes on the same street could have substantially different insurance costs and, consequently, very different total monthly payments. Buyers who focus only on getting a lower sale price may end up with a higher overall monthly obligation if they overlook these differences.

The Hidden Buying Power Equation

Weber argues that buyers should be calculating how much house they can afford based on their total monthly payment rather than the maximum purchase price. “Sometimes you might get a house and pay a little more for it, but you have lower taxes, and maybe you don’t have flood insurance, and that’s going to keep your costs down,” she says.

This approach can change which properties are truly affordable. For example, a buyer with a fixed monthly budget might be able to buy a more expensive home in a low-tax area without flood insurance than a cheaper home in a high-tax flood zone. Yet, according to Weber, many buyers continue to shop solely on sale price, missing better long-term deals.

Mortgage rates add another layer of complexity. Weber works with lenders who offer first-time homebuyer programs that are “either neighborhood specific or income specific” and can provide rates “almost a point less” than standard mortgages. These programs can save buyers hundreds of dollars per month, effectively increasing their purchasing power. Buyers who don’t know about these options or don’t work with lenders who can access them may unnecessarily limit their choices.

A one percentage-point reduction in mortgage rates often translates into monthly savings of several hundred dollars, and over the life of a loan, this can amount to tens of thousands of dollars. Weber emphasizes that understanding and accessing these programs are key to making an informed decision.

The Rate Recalibration

The way buyers think about mortgage rates is also changing. After years of ultra-low rates during and after the pandemic, many buyers were initially unwilling to accept higher rates when they rose above six percent. Weber says that the mindset is shifting. “People realizing that we’re not going to get a rate below three percent anymore, and they’ve just come to reality where they have to realize like, I missed that market, but six and a half percent is still below the national average for an interest rate,” she says.

This adjustment is bringing buyers back into the market who had been waiting for rates to drop further. Weber recently put three deals under contract between Christmas and New Year’s, a sign that serious buyers are moving forward despite higher rates.

This acceptance directly ties to the focus on monthly payments. Buyers who recognize that six to seven percent is now standard can plan for what they can actually afford, rather than delaying their search for rate conditions that are unlikely to return.

Market Sophistication

Weber’s experience suggests that today’s buyers need to understand how purchase price, property taxes, flood insurance, homeowner’s insurance, and mortgage rates all interact to determine true affordability. Those who can navigate these variables have a clear advantage in finding the best deals.

For real estate professionals, this means financial literacy and the ability to explain the total cost of ownership are more important than ever. Weber’s active involvement with lenders offering specialized programs reflects a shift toward more integrated real estate and mortgage services. Agents who can guide clients through the whole financial picture, not just negotiate sale price, are in a stronger position to help buyers succeed.

Whether this approach spreads beyond coastal markets with complex insurance requirements will depend on how quickly buyers and professionals in other regions recognize the importance of total monthly cost. However, in areas where hidden costs can significantly affect affordability, focusing solely on the purchase price leaves buyers at a disadvantage.

For now, Weber’s message is clear: buyers who account for every recurring cost are better equipped to make smart, sustainable decisions in today’s market. As insurance premiums, taxes, and mortgage rates continue to fluctuate, understanding the actual monthly payment will remain the most critical factor in determining what buyers can actually afford.
