How to read this tool
U.S. educational planning for a fixed-rate, fully amortizing monthly mortgage or a cash purchase. No loan approval, APR disclosure calculation, assistance eligibility or exact Closing Disclosure is produced.
Fictional example
Fictional inputs: $300,000 price and $60,000 down payment leave a $240,000 loan. Fees $9,000 plus prepaids $3,000 minus credits $1,000 and deposit $5,000 leave $66,000 due at closing. After $2,000 moving and $3,000 repairs, $90,000 available now leaves $19,000, or $9,000 above the selected reserve. The 6% rate is a hypothetical example.

Your scenario
Educational working copy. Not a loan offer, credit score, eligibility decision, application or professional advice.
Keep closing cash and total outlay distinct
The loan is price minus total down payment. Cash due now is down payment plus cash-paid closing fees and prepaids, minus eligible credits and the deposit already paid. Moving and immediate repairs are additional outflows. The reserve is retained cash, not a closing expense.
Use available cash after any deposit has already left your account. This prevents subtracting the deposit twice. The total purchase-cash result includes the paid deposit; the cash-due-now result does not. Credits and deposits here are bookkeeping inputs, not a determination of what a loan program allows.
Compare the mortgage payment with the full budget
Principal and interest use the contractual annual rate divided by twelve and the entered number of monthly payments. The displayed regular payment is rounded to cents. Property tax, insurance, association charges, mortgage insurance and an upkeep allowance are added once.
Annual property costs divided by twelve are planning averages. Actual bills, escrow collections, first-year prepayments and reassessments can have different dates and amounts. Utilities and other household spending belong in the non-housing field.
Test changes before treating a margin as spare money
The rate table varies the entered fixed rate by one percentage point in each direction, bounded at zero and 30 percent; other costs stay fixed. These are sensitivity scenarios, not available rates. A cash purchase produces no mortgage-rate effect.
Replace examples with written estimates and inspect the real Loan Estimate and Closing Disclosure. No adjustable rates, balloon payments, financed fees, taxes on a sale, insurance cancellation rules or lender debt-to-income decision are modeled. HUD describes counseling and online search options; services and fees vary by agency.
