Down Payments and Closing Costs

The two big upfront costs of buying a home, and the insurance product that exists specifically because of small down payments.

Before the first mortgage payment is ever due, buying a home requires a substantial amount of cash upfront - understanding exactly what that money covers helps in planning realistically for it.

The down payment and what it signals to a lender

A down payment is the portion of a home’s purchase price paid upfront in cash, with a mortgage covering the rest. The loan-to-value ratio compares the loan amount to the home’s value - a smaller down payment means a higher loan-to-value ratio, which lenders generally treat as a higher-risk loan, similar in spirit to the risk-based pricing covered in the insurance module.

Private mortgage insurance: the cost of a small down payment

Private mortgage insurance, or PMI, is typically required on conventional loans with a down payment below a certain threshold - commonly 20% - and protects the lender, not the buyer, if the borrower defaults. It’s an added monthly cost specifically tied to a smaller down payment, and it’s usually possible to have it removed once enough equity has built up in the home.

Why 20% down is such a commonly cited target

A buyer putting 20% down on a home typically avoids PMI entirely, which can meaningfully lower the monthly payment compared to the same loan with a smaller down payment. That's the specific reason 20% shows up so often as a target figure - it's not an arbitrary round number, it's the threshold where an extra monthly cost usually disappears.

Closing costs: the other upfront expense

Closing costs are a separate set of fees required to finalize a home purchase - loan origination fees, appraisal fees, title insurance, and various administrative costs - typically totaling a few percent of the home’s price, paid on top of the down payment itself.

Saving only for the down payment and forgetting closing costs

Closing costs are a real, often underestimated cash requirement on top of the down payment - someone who saves exactly enough for a 20% down payment can still find themselves short of cash at closing if they haven't separately budgeted for these fees. Planning for both figures together, well before making an offer, avoids a genuinely stressful last-minute scramble.

Why this connects to the rest of this module

The size of the down payment directly shapes the mortgage itself, including which type of rate structure - covered in the next lesson - makes the most sense for a given buyer’s situation.

Key takeaways
  • A larger down payment lowers the loan-to-value ratio, which lenders treat as lower risk.
  • PMI is typically required below a 20% down payment and protects the lender, not the buyer.
  • Closing costs are a separate, real cash requirement on top of the down payment itself.
  • Budgeting for both the down payment and closing costs together avoids a last-minute cash shortfall.
