How should a dentist invest a windfall or practice-sale proceeds?

Why not invest it right away?

Because a windfall triggers pressure — from salespeople, from relatives, from your own excitement — and pressure produces bad decisions. Parking the money in a high-yield savings account for a few weeks costs you almost nothing and buys you the clarity to make good choices. There’s no prize for rushing.

The order of operations

1. 1Park it safely — a high-yield savings or money market account while you plan.
2. 2Reserve the taxes — especially after a practice sale, a large bill may be due; don’t spend what you’ll owe.
3. 3Top up your emergency fund so you’re not forced to sell investments later.
4. 4Pay off high-interest debt — an immediate saving equal to the interest rate.
5. 5Invest the rest to a diversified plan, aligned with your goals.

How should you invest the remainder?

To a diversified, low-cost plan matched to your time horizon — not into a single concentrated bet. If putting a large sum in all at once feels daunting, easing in with a defined schedule is a reasonable compromise (lump sum vs. dollar-cost averaging). For proceeds meant to fund retirement, this is where a windfall becomes a durable income stream.

What if the windfall is your retirement?

For many dentists, the practice sale is a major piece of the retirement plan. That raises the stakes: the money now has to last decades, so the focus shifts from growth alone to a durable withdrawal and income strategy. Turning a lump sum into lasting income is its own discipline — and a good reason to plan the sale and the investing together, well before the check arrives.
