What Long Island Buyers Should Know
Updated September 21, 2026 | By Connie Intranova, Licensed Real Estate Salesperson
Mortgage rates can come down, but as of September 21, the evidence does not point to immediate or uninterrupted relief. The Federal Reserve has resumed raising its policy rate, inflation remains above target, energy prices are complicating the outlook, and investors are again considering the possibility of additional tightening.
For buyers, however, the most important concept is not whether the Fed will raise or lower rates at its next meeting. It is whether the bond market becomes willing to finance long-term mortgages at lower yields.
Where mortgage rates stand today
The national average for a 30-year fixed mortgage was 7.12% on September 21, according to Bankrate data reported by The Wall Street Journal's Buy Side team. The comparable 15-year average was 6.49%, while the average 30-year jumbo rate was 7.20%.
Freddie Mac's latest weekly survey, covering the week ending September 17, reported a lower 30-year average of 6.95%, up from 6.76% the previous week. The two readings are not contradictory. They use different methodologies, borrower assumptions and measurement windows, and neither is a personalized loan quote.
For Long Island buyers, the distinction is especially relevant because jumbo financing, property type, down payment, points, reserves and credit profile can produce materially different pricing from a conforming national average.
The Fed rate and your mortgage rate are not the same
On September 16, the Federal Reserve raised its target range for the federal funds rate by 0.25 percentage point to 3.75%-4.00%. The federal funds rate is an overnight bank lending rate. It affects short-term borrowing costs more directly than it affects a 30-year fixed mortgage.
A fixed mortgage is a long-duration financial asset. Its pricing depends more directly on longer-term Treasury yields, mortgage-backed securities, inflation expectations, prepayment risk and the spread lenders and investors require. This is why mortgage rates can fall before the Fed cuts, or rise even when markets expect future easing.
The Fed's new projections reinforce that distinction. The median policymaker projection places the federal funds rate at 4.1% at the end of both 2026 and 2027, before declining to 3.9% in 2028. Those projections are not promises, but they show that policymakers currently expect restrictive short-term rates to persist.
Why the inflation picture is still difficult
August CPI rose 0.4% for the month and 3.4% over the year. Core CPI, which excludes food and energy, increased 2.4% year over year. That core reading is constructive, but the energy index was 16.3% higher than a year earlier, and gasoline rose 3.9% in August alone.
Current events are amplifying that tension. Energy markets have been pressured by the U.S.-Israeli war with Iran, while tariffs and commodity-price shocks remain part of the inflation debate. On September 21, Chicago Fed President Austan Goolsbee said strong demand may now be adding to supply-driven inflation, potentially requiring a faster policy response if overheating becomes clear.
Markets are responding accordingly. Reuters reported that traders were pricing an 88% probability of another Fed increase in December. That pricing can change rapidly, but it illustrates why near-term mortgage-rate relief cannot be assumed.
The labor market is not forcing the Fed to retreat
The August employment report showed 162,000 additional payroll jobs and an unchanged unemployment rate of 4.1%. Average hourly earnings were 3.1% higher than a year earlier. That is reassuring for household income and credit quality, but it gives policymakers less reason to cut rates quickly to support employment.
What would actually make mortgage rates fall?
A sustainable decline would most likely require several developments to occur together:
Headline and underlying inflation move convincingly toward 2%.
Energy and commodity shocks fade rather than spread through services and wages.
Long-term Treasury yields decline.
Demand for mortgage-backed securities strengthens and mortgage spreads normalize.
Economic growth cools without producing a severe credit contraction.
Investors become confident that future Fed policy will be less restrictive.
The Fed does not have to cut first. Mortgage rates could decline in anticipation of better inflation data. Conversely, a future Fed cut would not guarantee lower mortgages if inflation expectations, Treasury supply or mortgage-market spreads remain elevated.
Three plausible rate scenarios
1. Gradual improvement. Inflation cools, geopolitical pressure eases and longer-term yields retreat. Mortgage rates trend downward, but unevenly, with periodic reversals around economic releases.
2. Higher for longer. Inflation remains persistent, demand stays firm or energy pressures continue. The Fed holds or raises again, and mortgage rates remain around current levels or move higher.
3. Faster decline during a downturn. A clear economic or employment deterioration pulls bond yields down. Financing becomes cheaper, but buyers may face weaker job confidence, tighter underwriting and renewed competition once rates fall.
What the payment difference looks like
On an illustrative $800,000, 30-year fixed loan, estimated monthly principal and interest would be:

This excludes taxes, homeowners insurance, mortgage insurance, association fees, points and closing costs. On Long Island, property taxes can materially change the complete monthly payment, so evaluate the full carrying cost, not the note rate alone.
Should buyers wait for lower rates?
Waiting is a market position. A lower future rate could reduce the monthly payment, but it could also bring sidelined buyers back into a market with limited well-located inventory. That can increase prices, reduce negotiating leverage and make contingencies less competitive.
The disciplined approach is to purchase only when the current all-in payment is sustainable. A future refinance should be treated as optional upside, not as the assumption that makes the purchase affordable.
Compare multiple lenders on the same day using the same loan assumptions.
Evaluate rate, APR, points, lender fees, cash to close and break-even period.
Compare permanent and temporary buydowns where seller credits are available.
Model conventional, jumbo and adjustable-rate structures when appropriate.
Stress-test taxes, insurance, maintenance and reserves.
Coordinate financing strategy with the specific property's likely competition and negotiation leverage.
The bottom line
Mortgage rates will eventually come down, but neither the timing nor the magnitude is knowable today. The September data argues for patience in forecasting—not necessarily patience in purchasing. Buyers should make decisions based on the property, their holding period, current affordability and available negotiating leverage rather than attempting to call the exact bottom in rates.
