The New Launch vs Resale Calculator, Explained

"Should I buy a new launch or a resale?" usually gets answered with vibes — new is shiny, resale is cheaper per square foot. The honest answer is a numbers question: over the years you'll actually hold it, which path leaves you with more, after interest, costs and growth? The New Launch vs Resale calculator runs both on the same budget and horizon and projects the net profit and the return on the cash you deploy for each.

What it actually compares

The two paths differ in ways that net against each other, and the calculator models each honestly. A new launch draws its loan down progressively as it's built, so you pay interest only on the drawn balance — meaningfully less interest in the early years — but you can't rent it out or build equity until it's finished, and you may be paying rent elsewhere while you wait. A resale is the mirror image: the full loan and its interest start on day one, along with maintenance, property tax and any renovation — but it can earn rent and compound value immediately.

You enter, for each side, the price, growth assumption, interest rate and the relevant carrying costs (rent-while-waiting for the new launch; maintenance, property tax and renovation for the resale), plus your LTV, tenure, horizon and ABSD profile. The calculator projects each side's gross gain from growth, the interest paid, the other costs, the net profit, and the return on equity (net profit over the cash you actually put in), then shows the delta between the two and the interest saving the progressive drawdown buys.

The assumptions to keep honest

The result swings hardest on the growth rates you assume for each side — and it lets you set them independently, because a new launch and a nearby resale don't always appreciate at the same pace. The buying expenses (BSD, ABSD, legal) can be toggled in so the comparison is total-cost, and the new-launch side assumes the loan is fully drawn by the horizon. As a feel for the mechanism: on a $750,000 loan over four years, a resale might carry roughly $36,000 of interest while the building-under-construction path carries about a third of that — the early-interest saving that partly offsets the rent you forgo while waiting.

How to read it

Open the New Launch vs Resale calculator, enter both paths, and read the net-profit delta and the return on equity — not just the headline profit, since the two paths often tie up different amounts of cash. Then stress the growth assumptions: set them equal first to isolate the cost difference, then vary them to reflect your actual view. The tool won't tell you the future; it tells you what has to be true about growth for one path to beat the other, which is the decision that matters.
