How much house can I afford with a $100k down payment?

With a $100k down payment at 20%, you can afford a $500,000 home. At 10% down, you can afford up to $1,000,000. The optimal amount depends on your income, location, and comfort with mortgage insurance.

Is $100k enough to avoid PMI?

A $100k down payment avoids PMI (20% down) on homes up to $500,000. For more expensive homes, you'd need a larger down payment or accept PMI, which typically costs 0.2% to 2% of the loan amount annually.

Should I put down 20% or less with $100k?

It depends on your goals. 20% down avoids PMI and lowers monthly payments. Less than 20% lets you buy a more expensive home but adds PMI costs of $100-$500/month.

How far does $100k go in different housing markets?

In affordable markets like Ohio or Texas, $100k can be 25-50%+ down on a home. In expensive markets like San Francisco or New York, it may only be 10% or less of the purchase price.

Is $100,000 Enough for a Down Payment?

A $100,000 down payment is substantial and puts you in a strong position to buy a home in most U.S. markets. However, “enough” depends on where you’re buying, your target home price, and whether you want to avoid mortgage insurance.

How Much House Can You Afford?

Down Payment %	Home Price with $100k Down
5%	$2,000,000
10%	$1,000,000
15%	$666,667
20%	$500,000
25%	$400,000

Key consideration: Just because you can put less down doesn’t mean you should. Larger down payments mean lower monthly payments and no PMI.

When to Put Down Less Than 20%

Consider putting down less than 20% if:

Home prices in your area are rising faster than you can save
Your rent is higher than your potential mortgage payment
You have a stable income and can handle PMI
You’re buying in an appreciating market

When to Wait and Save More

Consider waiting if:

You’d deplete all savings for the down payment
You have high-interest debt to pay off first
Housing market in your area is cooling
Your job situation is uncertain

The Bottom Line

$100,000 is absolutely enough for a down payment in most U.S. markets. It allows you to:

Buy a median-priced home in over 70% of U.S. metros with 20%+ down
Avoid PMI on homes up to $500,000
Have significant equity from day one

The key is matching your down payment to your local market and financial situation. In affordable markets, $100k can make you a strong buyer. In expensive coastal cities, you may need to decide between a smaller home, a longer commute, or accepting PMI.
