Down Payment, Closing Costs, and Cash Reserves
Plan the cash required to close without assuming every available dollar belongs in the down payment.
- The down payment is only one use of cash at purchase.
- Closing costs, moving expenses, immediate repairs, and a post-closing reserve deserve separate lines.
- A larger down payment can reduce borrowing costs but may weaken liquidity if it drains savings.
- Compare actual loan options at different down-payment levels instead of treating 20% as a universal rule.
Twenty percent down—or an empty account
Luis has enough saved to put 20% down only if he uses nearly every dollar. The home also needs an aging water heater replaced soon. He asks lenders for comparable options at different down payments, estimates closing costs, and protects a repair and emergency reserve before deciding how much cash belongs in the transaction.
Create four cash buckets
Separate the down payment, closing costs, moving or setup expenses, and money that remains after closing. CFPB guidance specifically treats closing costs separately when estimating the maximum down payment a buyer can afford.
The final numbers depend on the property, location, lender, and loan. Use the Loan Estimate rather than an internet rule of thumb once you have a specific offer.
A larger down payment has benefits and tradeoffs
Putting more down generally reduces the amount borrowed and may lower the payment or mortgage-insurance cost depending on the loan. It also moves liquid cash into home equity, where accessing it later may require selling, refinancing, or borrowing against the property.
Ask lenders to show comparable scenarios. The right comparison includes rate, mortgage insurance, fees, monthly payment, total loan cost, and the cash left afterward—not the down-payment percentage alone.
Protect the first months of ownership
New owners can face repairs, tools, utility deposits, insurance deductibles, moving expenses, and items an inspection could not predict. An emergency fund exists specifically for unplanned expenses such as home repairs or income loss.
A known near-term repair should not be treated as an emergency surprise. Put it in the purchase budget and negotiate or plan accordingly.
Verify assistance and gift rules
Down-payment assistance, grants, and family gifts can be useful, but eligibility, documentation, repayment, lien, occupancy, and lender requirements vary. Confirm the rules with the program and lender before counting the money as available.
Avoid wiring funds based only on emailed instructions. Real-estate transactions are frequent targets for wire fraud; independently verify destination and instructions through trusted contact information before sending money.
