How much should you put down?

The down payment is almost always decided by one number: the minimum the bank will approve.

And that's rarely the right number for you. Just because the bank approves something doesn't mean it's comfortable to live with.

Because the down payment is, at its core, how much of your capital you tie up today — and how much you keep within reach.

Putting down more lowers the payment, saves you interest over time, and gives you margin if rates rise. But you tie up more money at once — money that's no longer available for an emergency, an opportunity, or simply to sleep at night.

Putting down the minimum keeps you liquid and with capital for other things. But your payment goes up, you pay more interest along the way, and you go in with less cushion if something changes: a bad month, a vacancy, an expense you didn't expect.

And here's what almost no one weighs: a low payment feels reassuring, but running out of liquidity usually does the opposite.

And a mistake that costs dearly: budgeting only for the down payment.

Then come closing, the lawyer, insurance, the move, the repairs, and whatever inevitably shows up once you have the keys.

The down payment isn't all the cash you're going to need.

A Panama-real nuance: in pre-construction, the down payment is built up in installments during construction — gentler. That helps, but it also makes many people underestimate how much capital they'll really need at the end. With resale, it usually goes in full on closing day.

What worries me is when someone hands over almost all their liquidity in the down payment to "owe less" — and comes up short right when something changes.

The right down payment isn't the highest or the lowest. It depends on your liquidity, how stable your income is, and what else that money could be doing. If that capital has a better use and you're comfortable with the risk, putting down the minimum can make sense. If not, putting down more takes debt off your back.

And here's the question that really matters: how much are you left with after putting it down?

Before deciding how much to put down, I'd add up all the cash the purchase really needs —down payment, closing, and what comes after— and from there I'd see how much to put down without coming up short.

The right down payment usually isn't the one that makes you proudest.

It's usually the one that lets you sleep at night after paying it.
