Buying your first house is a huge milestone — and if you're a doctor or healthcare professional, you've worked way too hard to have your home purchase become a financial headache.
But let's be honest: the process can feel overwhelming. Mortgage jargon, endless paperwork, hidden costs — it’s enough to make anyone want to retreat to their hospital call room.
Let’s slow it down and walk through the essentials of buying your first home wisely, so you can move forward with confidence (and without feeling cash-strapped).
Step 1: Focus on Two Things — Down Payment and Monthly Payment
When it comes to buying a house, everything really boils down to two key questions:
- How much should I put down? (Down Payment)
- How much can I comfortably afford every month? (Monthly Payment)
If you get these two things right, you’re setting yourself up for long-term success.
Down Payment: How Much Is Enough?
Here’s the deal: If you don’t put 20% down, banks usually require you to pay for something called Private Mortgage Insurance (PMI). It's basically an extra insurance policy you pay for because the bank is worried you might bail on them.
Under 20% down = PMI = higher monthly cost
20% or more down = no PMI = lower monthly cost
Good news for doctors:
Many lenders offer physician mortgage loans that allow you to put less than 20% down without having to pay PMI. Some programs even allow you to put as little as 0% down, though it's important to read the fine print. In some cases, a lower down payment can mean a higher interest rate and so it might still be worth looking at conventional loans with PMI.
Pro tip: Even if 0% down sounds tempting, a 5–10% down payment is often a healthier goal. It gives you some cushion in case the housing market dips — because if you owe more than your home is worth (called being underwater), selling or moving becomes much harder and more expensive.
Don't Forget About Closing Costs
Besides your down payment, you’ll also need cash for closing costs — things like loan origination fees, title insurance, taxes, and more.
Typical range:
- 2–3% of the purchase price
- Example: A $600,000 house might come with $12,000–$18,000 in closing costs.
Common mistake:
Focusing only on the down payment and forgetting about these costs. Then scrambling for money when it’s time to close.
Bottom line:
Make sure you keep at least 3–6 months of emergency savings intact after your home purchase. Your future self will thank you.
Real life reminder:
When my wife and I bought our first house, we had to replace the entire roof within the first month. That was a $15,000 expense you don’t want to charge to a credit card right out of the gate.
Quick Trick: Seller Concessions
Depending on the market, you might be able to negotiate seller concessions to have the seller cover some of your closing costs.
It’s worth asking your realtor — especially if you’re trying to conserve cash — but in very competitive markets, concessions may be harder to win.
Step 2: Know What You Can Actually Afford Monthly
When calculating your monthly mortgage cost, don’t just use a basic loan calculator online. Your real monthly payment includes:
- Principal (the loan amount)
- Interest (your mortgage rate)
- Taxes (property taxes)
- Insurance (homeowner's insurance)
(Shorthand for this: PITI — Principal, Interest, Taxes, Insurance.)
Bonus: Don’t forget about HOA fees if you’re buying in a neighborhood with a homeowners’ association.
Some online calculators like Zillow and Realtor.com do a decent job of estimating taxes and insurance based on the property, but always double-check.
The 28% and 36% Rules (And How to Bend Them Without Breaking)
Our CFP® Board recommends:
- Your full housing payment (PITI + HOA) = 28% of your take-home pay
- Your total debt payments (housing + student loans + car loans + credit cards) = 36% of your take-home pay
Example:
- Bring home $10,000/month
- Ideal housing payment = about $2,800–$3,000/month
Now, reality check: If you’re buying in California, New York, or any other high-cost-of-living area, you might look at these numbers and think, "You want me to live in a shack??"
(Yes, my clients in California have given me that look.)
And that’s okay. Going over these guidelines doesn't automatically make you "house poor."
It just means you’ll have to compensate elsewhere — by saving less temporarily, reducing discretionary spending, or adjusting your financial priorities.
If you don’t adjust elsewhere, then yes, you’ll likely end up feeling cash-strapped, stressed, and like you’re spinning your wheels — all while living in a beautiful house you can't fully enjoy.
The key is being honest with yourself:
- If you stretch the housing budget, where will you pull back?
- Are you comfortable with those trade-offs?
Watch Out for the "Qualified" Trap
When you talk to a mortgage lender, they’ll tell you what you qualify for.
Qualified ≠ Affordable
All "qualified" means is what the bank is willing to risk on you — not what’s actually wise for your long-term financial health. Big difference.
Be the adult in the room for your own financial life. Set your own limit based on your overall budget, not just what a lender says you can borrow.
Step 3: Think About Your Exit Strategy
Okay, let’s play out a worst-case scenario for a second (because that’s what calm, prudent people do).
What if you:
- Buy the house
- Hate your new job
- Need to move within a year?
If you’re underwater (owe more than the house is worth), you’re stuck. Either you cough up the difference to sell, or you rent it out.
Tip: Before you buy, check local rental rates for similar homes. If your monthly payment would be close to what you could rent it out for, you’ll have a much safer fallback plan.
We typically recommend being comfortable holding onto the house for at least 10 years — even if life throws curveballs. It’s just a safer bet in today’s unpredictable market.
Two Final Questions Before You Buy
Whenever you’re about to make a big financial decision, especially buying a house, slow down and ask yourself:
- Is this the right time?
Not just for your emotions, but for your finances too. - Am I rushing this?
Spoiler: If you feel rushed, you probably are. And as Proverbs reminds us, “He who hurries his footsteps errs.” Or as we say at HumbleWealth: Haste makes waste.
Take a breath. Zoom out. You’re not just buying a house — you’re setting up the next chapter of your life.
Make sure it's a chapter you actually want to read.
Long Story Short (LSS)
Buying a home should be exciting, not a fast track to buyer’s remorse. A little homework and a clear sense of what you can truly afford go a long way in keeping you grounded.
