Everyone says you have to put 20% down when buying a house.
I’m calling BS!
That’s terrible advice and I’ll prove it with math.
Ya that’s right, I can math. I can also write good and dance gooder (don’t ask me to do either plz).
Let’s start with the goal
Let’s use a $450,000 house as the example. This is roughly the median home price in the U.S.

How much do I put down?
First, downpayment. The MINIMUM in the U.S. is 3%.
If you put less than 20% down, you have to pay mortgage insurance (we’ll get back to that).
But let’s assume 3% downpayment for now, which on a $450,000 house…
= $13,500
But that’s not all?
Oh, GOD NO.
Next is closing costs. These cover lender fees, appraisal, government records, home inspection blah blah blah. A bunch of random things.
These can be as much as 2-5% of your house purchase value.
Or in this case…
= $9,000 to $22,500

Are we done?
Hell nah.
Next is moving costs. Of course this ranges - do you have a pack of selfless (borderline fool-hardy) friends who are willing to blow up an entire Saturday lugging heavy stuff for you with the promise of beer and pizza?
Me neither.
Even for a local move, costs can be…
= $3,000

Please tell me no more…
Sorry, pal. Here’s what’s left:
House emergency repair fund: budget 1-3% of your home value annually…
= $4,500 to $13,500
Furniture and other necessities can be…
= $10,000 to $30,000 or more
(do you aspire to Versailles or a more stoic style?)
That’s already…
= $40,000 to $82,500 all in!!
So what’s the kicker?
73% of first-time home buyers put down 15% or less.

With the median downpayment around 9%.
So it seems most people aren’t practicing the “20% downpayment mantra”.
But I don’t want to pay mortgage insurance!
Actually, you kind of do.
Trying to save up $90,000 for a downpayment (with our $450,000 house example) means you’ll lose more to rising home prices that you would save on private mortgage insurance.
Private mortgage insurance costs 0.3% to 1.2% on average:

While home price increases have far exceeded that in recent years:

So what should I do?
So what should I do?
Target 15% of the price of your home - that’s your real savings goal.
= $67,500
That will comfortably cover a basic downpayment and all closing costs. It’ll get you in the market and on the scoreboard.
Is this genius or chaos? Let me know!
