Buy now, or wait?

Waiting feels safe — but if rates drop and prices rise, waiting can cost more than buying at the wrong time. Plug in your guess (or worst case) for next year, and see what happens.

Verdict: The two scenarios are within $642 of each other over 7 years, counting the equity you keep. Neither timing has a strong financial edge — the decision should rest on life factors (job stability, family situation, school timing).

Counted: rent while waiting, the purchase-price difference, and mortgage interest over the same 7-year window — down payment and principal are equity you keep, not costs. Not counted: property tax, insurance, and maintenance (near-identical in both paths), transaction costs, and what your down payment could earn while you wait.

The honest caveat

The two biggest variables here — what the rate is in 12 months and what the price is — are unknowable. The point of this calculator isn't to predict; it's to show you how big the move would have to be. If the rate has to drop to 5.72% in 12 months for waiting to pay off, that's the bar your forecast has to clear.

How the math works (plain English)

Two things can change while you wait: price and rate. A higher price means more down payment and a bigger loan. A lower rate means a smaller monthly payment for the same loan. They push in opposite directions, and which one wins depends on the size of the moves.

We build both paths over the same 7-year window and compare what each one actually costs you: rent paid while waiting, the purchase-price difference, and the mortgage interest (P&I only) each path racks up. Your down payment and the principal you pay off are equity you keep, not money spent — counting them as costs is the classic mistake in buy-vs-wait math. The rent while waiting is the part most "wait for rates to drop" advice ignores — and it's often the biggest single cost of waiting.

Important honesty: nobody can forecast rates. The point of this tool isn't to predict — it's to show you how big the move has to be for waiting to actually pay off.

Our read — Q3 2026

Every tool on this site runs on the same working assumption: the current 30-year fixed rate, updated weekly (the rates page shows it, with the date); the affordability tool stress-tests at 7.5%, and each calculator names its own sensitivity convention where it appears. We don't forecast rates, and we distrust anyone who does. Our read is a rule, not a prediction: buy when the stress-rate payment is comfortable and your hold is five years or longer. Wait only when the break-even rate this tool computes is one you would genuinely bet your housing on — remembering that every month of waiting has a rent cost the calculator counts against you, and that a lower rate later is a refinance opportunity for the buyer who acted, not just a reward for the one who waited.

Our read is reviewed quarterly (next: October 2026). The 30-year rate itself updates weekly from Freddie Mac’s survey — the rates page always carries the current figure and its date.

Nuestra lectura — T3 2026

Todas las herramientas de este sitio corren sobre el mismo supuesto de trabajo: la tasa fija a 30 años vigente, actualizada cada semana (la página de tasas la muestra, con su fecha); la herramienta de capacidad de compra aplica la prueba de estrés a 7.5%, y cada calculadora nombra su propia convención de sensibilidad donde aparece. No pronosticamos tasas, y desconfiamos de quien lo haga. Nuestra lectura es una regla, no una predicción: compra cuando el pago a la tasa de estrés sea cómodo y tu horizonte sea de cinco años o más. Espera solo cuando la tasa de equilibrio que calcula esta herramienta sea una a la que de verdad apostarías tu vivienda — recordando que cada mes de espera tiene un costo de renta que la calculadora te cuenta en contra, y que una tasa más baja después es una oportunidad de refinanciamiento para quien compró, no solo un premio para quien esperó.

Nuestra lectura se revisa cada trimestre (próxima: octubre 2026). La tasa a 30 años se actualiza cada semana con la encuesta de Freddie Mac — la página de tasas siempre muestra la cifra vigente y su fecha.
