How Proposed 2026 Tax Changes Affect Homeowners and Buyers

Proposed tax legislation for 2026 could significantly alter the financial landscape for homeowners and prospective buyers. Key changes center on the deductions for mortgage interest and state and local taxes (SALT), which may increase the after-tax cost of homeownership, particularly in high-tax states and for those purchasing high-value properties. While an increased standard deduction offers relief for some, the overall impact requires careful assessment based on individual circumstances. This analysis outlines the potential effects on your real estate decisions.

What are the proposed changes to the mortgage interest deduction? A major shift involves the mortgage interest deduction. Under current law, homeowners can deduct interest on mortgage debt up to $1 million. The proposed plan would lower this cap to $500,000 for new home purchases. This change would primarily affect buyers in higher-priced real estate markets. For example, the interest on a $750,000 mortgage would only be partially deductible. It's crucial to note that this is projected to apply to new mortgages originated after the law takes effect; existing mortgages are generally expected to be grandfathered under the old rules. This makes the timing of a purchase an important financial consideration.

How does the cap on state and local tax (SALT) deductions impact homeowners? The treatment of State and Local Tax (SALT) deductions is another critical area. The proposal aims to repeal the full itemized deduction for state and local income and sales taxes, allowing only a deduction for property taxes, capped at $10,000. This is a significant consideration for homeowners in states with high property taxes, such as New York and New Jersey. For these individuals, the tax benefit of owning a home could be substantially reduced, potentially affecting housing affordability and resale value in those markets. Based on our experience assessment, this change makes calculating your true monthly housing cost more important than ever.

Will the higher standard deduction benefit me as a homeowner? The plan calls for a near-doubling of the standard deduction. For married couples filing jointly, it would increase to $24,400. This change is pivotal because it means far fewer taxpayers will find it advantageous to itemize their deductions. If the total of your itemized deductions—including mortgage interest, charitable donations, and the capped property tax—is less than the new standard deduction amount, you will simply take the standard deduction. This simplification may benefit many homeowners by providing a larger deduction without the need to track individual expenses, but it also diminishes the tax-saving value of mortgage interest for a larger segment of the population.

What other tax changes should real estate investors consider? The proposed repeal of the Alternative Minimum Tax (AMT) and changes to treatment of pass-through business income could benefit individuals involved in commercial real estate or those who own rental properties. The AMT often disallowed deductions for state taxes and depreciation, so its removal could lower tax liability for some investors. Furthermore, lower rates on unincorporated business income (pass-through income) could directly advantage real estate LLCs and sole proprietorships. However, these provisions are complex and interact with other parts of the tax code, so consulting with a tax professional is strongly recommended.

In conclusion, the proposed 2026 tax changes present a mixed picture for the real estate market. The reduction in the mortgage interest deduction cap and limit on SALT deductions may cool demand in high-cost areas. Conversely, the higher standard deduction offers a broader benefit to moderate-income homeowners. When considering a purchase, calculate your potential tax liability under the new rules and factor it into your affordability assessment. The most practical advice is to stay informed on the final legislation and base your decisions on a clear understanding of how these changes personally affect you.
