How the cash to close calculator works
The three layers of closing cash
Down payment (the famous number), closing costs (2–5%: lender fees, title, appraisal, recording), and prepaids (several months of taxes and insurance deposited into escrow at signing). First-time buyers routinely budget for the first and get ambushed by the second and third — together they add 5–9% of price beyond the down payment.
The reserve is the real qualification
Lenders check reserves for some loans; common sense checks them for all. A household that arrives at closing with exactly zero has converted every shock — appliance, job, roof — into high-interest debt. Three months of full housing expenses (about 4% of price on a typical budget) is the defensible minimum; six is calm.
Where the cash can legally come from
Savings, gifts (documented with a gift letter), sale of assets, and first-time-buyer assistance programs in many states. Not: borrowed down payments disguised as gifts, or undisclosed loans — underwriters trace large deposits, and misrepresented sources kill loans late in the process.
