The down payment is your "skin in the game." It is the upfront cash you pay toward the purchase price of the home. While the "20% down" rule is often cited as the gold standard, it is no longer a strict requirement for most buyers . However, the size of your down payment has a massive ripple effect on your monthly costs, specifically regarding Private Mortgage Insurance (PMI).

The 20% Myth vs. Reality

For decades, 20% was the magic number. If you bought a $300,000 home, you were expected to bring $60,000 to the table. Today, the average down payment for first-time homebuyers is closer to 11% . Some programs even allow for as little as 3% or 3.5% down .

Why Lenders Love 20%

Lenders prefer a 20% down payment because it provides a safety buffer. If the housing market dips and you need to sell, you are less likely to owe the bank more than the home is worth. Because you have more equity, you are considered a "lower risk" borrower, which often results in a better interest rate .

Private Mortgage Insurance (PMI): The Cost of Low Equity

If you put down less than 20% on a conventional loan, the lender will require you to pay for Private Mortgage Insurance (PMI) .

Crucial Distinction: PMI does not protect you. It protects the lender in case you default on the loan . It is an added monthly fee that provides you with no direct benefit other than allowing you to buy a home with a smaller down payment.

How Much Does PMI Cost?

PMI typically costs between 0.46% and 1.5% of the total loan amount annually . On a $250,000 loan, a 1% PMI fee would add about $208 to your monthly mortgage payment.

Removing PMI

The good news is that PMI isn't forever on conventional loans. Once you reach 20% equity in your home—either by paying down the principal or through the home's value increasing—you can request to have PMI removed . By law, lenders must automatically cancel it once your equity reaches 22%.

FHA Loans: A Different Insurance Path

For buyers with lower credit scores or limited savings, FHA loans (insured by the Federal Housing Administration) are a popular alternative. They allow for a down payment as low as 3.5% with a credit score of 580 or higher .

However, FHA loans handle insurance differently. Instead of PMI, they use MIP (Mortgage Insurance Premium) .

Upfront MIP: A one-time fee (usually 1.75% of the loan) paid at closing .
Annual MIP: A monthly fee paid as part of your mortgage.

The Catch: If you put down less than 10% on an FHA loan, you must pay the monthly MIP for the entire life of the loan . To get rid of it, you would eventually have to refinance into a conventional loan once you have enough equity.

Comparing Down Payment Options

Loan Type	Min. Down Payment	Insurance Type	Can Insurance Be Removed?
Conventional	3% - 5%	PMI	Yes, at 20% equity .
FHA	3.5%	MIP	No (if <10% down) .
VA Loan	0%	None	N/A (No monthly insurance) .
USDA Loan	0%	Guarantee Fee	No (usually for life of loan).

Strategies for Saving Your Down Payment

Down Payment Assistance (DPA): Many states and local governments offer grants or low-interest loans to help first-time buyers with their down payment .
Gift Funds: FHA and some conventional loans allow you to use "gifted" money from family members, provided there is a signed letter stating the money does not need to be repaid .
The "House Hack": Some buyers use a low-down-payment FHA loan to buy a 2-4 unit property, living in one unit and renting the others to cover the mortgage .

Step-by-Step: Calculating Your Target

Determine your budget: Use the 28/36 rule (housing costs < 28% of gross income) .
Check your cash: Total your savings, but subtract 3-5% for closing costs (fees for taxes, appraisals, and loan origination) .
Decide on the percentage: If you have 10% saved, decide if you'd rather put it all down to lower the monthly payment or keep 5% as an emergency fund and pay a slightly higher PMI.
