How much house can a doctor afford on a real monthly budget?

A physician asking how much house a doctor can afford gets a cash-flow answer from Annex Wealth Management: choose a payment that fits after saving, debt payments, and ordinary spending. A useful first screen is to keep total housing near 30% or less of monthly take-home pay. Then confirm the payment still fits in what is left after debt payments and planned retirement savings. A lender measures debt differently. Annex Wealth Management wrote this for physicians and dentists with high income, where a large approval letter can distract from the monthly plan.

What does a house budget have to answer first?

A house is affordable when its full monthly cost fits after planned income draws, debt payments, retirement savings, and ordinary spending. Count principal and interest, property taxes, insurance, maintenance, utilities, association dues, and any physician mortgage charges. The lender's approval letter answers whether a loan may be available; it does not answer whether the payment leaves room for your life.

Annex Wealth Management begins with your monthly budget because the portfolio is there to pay for your life. It should not have to bail out a mortgage that only works when markets cooperate. Income draws are money taken from investments or retirement accounts to cover expenses. A lender's approval amount also may not account for practice costs, uneven 1099 income, alimony, tuition, or the reserve you want to keep.

How should two physicians talk about the purchase at home?

The person who first reacts to the approval letter should bring the number home as a question, not a decision. Usually, the higher earner or the physician who has been house hunting raises it first. Before discussing square footage, write down the monthly plan: practice expenses, locums income, retirement savings, ordinary spending, and cash set aside for repairs. Then agree on a payment that still works if locums shifts disappear for several months.

Which age milestones change the housing decision?

We assume a physician's work pattern and income sources will change. A mortgage that fits during peak saving years may feel heavier once you cut clinical hours or start income draws. Write down the age you expect to change how you work, and test the payment against the income you expect then.

What does a cash-flow test look like for Jun and Patrice?

Jun and Patrice, a hypothetical couple, are 44 and 43, have $900,000 saved, and receive $80,000 a year from locums work. Their student loans are paid off, and they are considering a $1.6 million home. They estimate $32,000 in monthly take-home pay. From that, they reserve $8,000 for retirement saving and spend $11,000 outside housing: $32,000 - $8,000 - $11,000 = $13,000 left for housing and extra margin.

For the larger home, assume a physician mortgage with $160,000 down and a $1.44 million loan. The estimated monthly principal and interest are $9,000; taxes, insurance, and maintenance add $2,000. That makes housing $9,000 + $2,000 = $11,000. Dividing $11,000 by $32,000 gives 34.4% of take-home pay, and $13,000 - $11,000 leaves $2,000 after their listed saving and spending.

The smaller option is a $1.2 million home with $120,000 down. Its estimated principal and interest are $6,000 each month, with $1,500 for other housing costs. The total is $6,000 + $1,500 = $7,500, or $7,500 divided by $32,000 = 23.4% of take-home pay. Subtracting the payment from their $13,000 housing allowance leaves $5,500.

The $1.6 million choice could work if the $32,000 take-home amount stays dependable and they keep a separate reserve. If monthly take-home pay falls below about $29,000 for a sustained period, the larger home stops working. At $29,000, subtracting $8,000 of saving and $11,000 of other spending leaves $10,000, less than the $11,000 housing cost. The smaller home's $7,500 still fits, and it also sits below 30% of $29,000, which is $8,700. Investments can lose value, so they should not treat the portfolio as guaranteed mortgage support.

Annex Wealth Management would put the monthly payment beside the saving target and work plans before treating the lender's maximum as a household budget. The arithmetic narrows the choice; Jun and Patrice still need to decide whether the larger home is worth having only $2,000 of monthly margin.

What should the mortgage paperwork show before an offer?

Ask the lender for the full monthly payment at the proposed down payment, including taxes, insurance, any mortgage insurance, and rate-reset or refinance terms. Ask your CPA whether 1099 locums income is counted after business expenses and estimated taxes; gross receipts are not spendable pay. Ask the plan administrator how saving fits the 403(b), solo 401(k), or other available accounts, and ask an advisor to place the payment beside your monthly plan.

  • Net locums income after costs
  • Retirement account contribution rules

Which generic house rule causes trouble?

Treating a salary multiple or lender approval as the household ceiling can turn Jun and Patrice's $13,000 monthly amount left after saving and spending into an $11,000 housing obligation. That happens before practice costs, travel, repairs, and family spending are counted.

Keep total housing near or below 30% of monthly take-home pay, and check that it still fits after required debt payments and planned retirement saving. If the payment exceeds that screen, pause unless you can name the spending you will reduce and the reserve that protects the plan.

What can you do alone, and where is a conversation useful?

You can total the proposed housing costs, subtract them from monthly take-home pay, and test the result against savings, debt payments, and work plans for the next five years. A conversation with Annex Wealth Management is useful when the purchase competes with solo 401(k) saving, taxable investing, a practice decision, or a planned reduction in work; bring the lender worksheet, monthly plan, recent pay details, and proposed down payment.

Common follow-up questions

Is a physician mortgage better than putting 20% down when the monthly payment fits?
A physician mortgage can preserve cash for a practice or reserve, but a smaller down payment often means a larger loan and payment. Compare the full monthly cost, including any mortgage insurance or rate-reset terms, with the cost of putting 20% down. The lower payment matters only if the money kept back has a specific job.
Could this housing rule be too cautious for two physicians with $900,000 saved?
It could be. The $900,000 saved is not all available for a down payment if some is earmarked for retirement, taxes, practice needs, or emergencies. Run the housing payment through the monthly spending plan first. A rule near 30% is a screening point, not a command to buy less when dependable income and reserves support the larger payment.
What happens if our income rises after we buy the house?
Higher income can make the payment easier to carry, but it does not automatically make the larger house the better choice. First decide how much of the increase will go to savings, practice costs, and ordinary spending. Then revisit the monthly plan; the house should not quietly absorb every raise.
Can we change the down payment or refinance later if the payment strains our cash flow?
You can ask the lender whether a larger down payment would lower the payment, but using cash reduces the reserve available for repairs or a work interruption. Refinancing later is not guaranteed; rates, home value, income, and lender rules can change. Set a payment you can carry without relying on a future refinance.
Should 1099 locums income count when we set our house budget?
Count locums income only after business expenses and estimated taxes, and use an amount you believe will continue. If shifts vary, test the budget with several months of lower income or without the locums work. A lender's treatment of gross receipts may differ from the spendable amount your household can safely use.
