The Payment-First Mortgage: How Physicians Should Set Their Housing Budget

A physician couple came to us last year with a pre-approval for $1.4 million from their bank. They were thrilled. Then we built their actual monthly budget together and watched the excitement drain out of the room: carrying $1.4 million would've eaten the student loan payments, her maternity leave plan, and every dollar they'd earmarked for a future practice buy-in.

They bought at just over $1 million. Nobody regrets it.

That's the problem with how physicians are told to shop: everyone hands you a maximum. The bank gives you a maximum approval. The physician programs, which are genuinely generous, give you an even bigger one. Nobody asks what payment actually fits your life. So let's do that instead.

Work backwards from the payment, not forwards from the price

Here's the exercise. It takes one evening.

Start with what actually lands in your personal account each month. Not billings, not gross - deposits. Say that's $14,000 for a new-in-practice physician, after tax and after what stays in the corporation.

Now subtract the life you're keeping:

• Student line of credit payments: $1,200
• Retirement catch-up and investing: $2,000
• Disability and life insurance: $500
• Childcare: $1,800
• Everything else it costs to be alive: $3,200

That leaves $5,300 for housing, all-in. Property tax, utilities, and a maintenance buffer on a detached home will take about $1,200 of it. So the mortgage payment this family can carry without wincing is roughly $4,100 a month.

And here's what that converts to: at an illustrative 4.5% on a 25-year amortization, $4,100 a month carries a mortgage of roughly $740,000. Add your down payment on top and that's your price range. Not the bank's number - yours. (Illustrative rate, not a quote. Your real rate moves that number, which is why we run it live with you.)

Why physicians get burned by the forwards version

Physician cash flow is weird, and maximum-approval math ignores everything weird about it. Your income might be brand new, or flowing through a corporation, or about to dip for a fellowship or a parental leave. Your student line of credit is real, and the leading physician programs count it in your ratios even before you're repaying it. And the gap between year-one and year-five earnings tempts everyone to borrow against the year-five version of their life.

Don't. Size the payment to this year's income and let the raises shorten the mortgage instead of justifying a bigger one. Prepayment privileges exist for exactly this: buy on today's cash flow, then hammer the balance when the income shows up.

The Match tool runs this with you

We built the free Match tool at physicianfinancing.ca/match around this exact method. You put in your stage of career, how your income is structured, your debts, your down payment. It works through the budget payment-first and shows which physician programs fit. No credit pull, nothing sent to any lender, and it works at 11pm after a shift, which is when most physicians actually deal with this stuff.

Do the envelope math first. Then let us fight to make that payment buy as much house as possible. That part's our job.
