Good, bad, or terrible idea???
If the market totally collapses in 6-12 months, it's just so tempting. Two year partner track. Full disclosure, median desirable house here is like 1-2 million so it's not a small purchase. Open to a starter house for 1.5, but ultimately family home here will be 2.5 to 3. Down payment is currently in stock market, so it's down 15% right now, but have roughly 500-600k in stocks between the two of us for a house.
I'm generally a proponent of physicians buying their homes and generally dislike renting.
$3 million is a lot to take on for your first home though.
How bad of a home is $1.5 million?
What is your monthly combined net income?
What is the property tax rate? Homeowners insurance rate?
Those will all have a large impact on your total cost of owning this house.
The state you are in is also important. For example, California is a non recourse state and has Prop 13 to keep property tax rates stable for long time homeowners.
Don't forget that you are limited on the amount of mortgage interest you can deduct on your federal taxes as well as the SALT cap.

Ultimately, real estate is very local. If the area you are interested in is very desirable, I wouldn't expect a huge decline in values.
For me though, owning a home has been a reasonable way to control my housing costs.
I bought a new construction in a suburb with a good school district in California. Original mortgage rate was 4% with monthly cost at $3551 ( not including taxes and insurance). Because of declining mortgage rates I was able to refinance twice and am sitting at 2.75% with a monthly rate of $2889.
While rents are going up, I am holding steady with a fixed house price and borrowing money at an absurdly low rate

My advice,
Don't overextend yourself too much buying your first home. You will have much more peace of mind if you can support the mortgage on one income.
Make sure the area is safe and the schools are good. This will help keep property values high and help in resale if needed.
It can be a headache to own but I like it infinitely better than renting.
