The starting point

A useful homebuying plan answers three questions: What monthly payment fits your life? How much cash will you need upfront? And which mortgage structure supports both? Start there before treating a preapproval amount as a shopping budget.

A comfortable budget comes before a maximum loan amount.

A lender evaluates income, debts, credit, assets, and the loan’s requirements. Your household also has expenses that a qualification calculation may not fully capture: childcare, groceries, retirement saving, travel, and maintaining the home. Your comfortable payment may be below the amount a lender will approve.

Build the budget around the full housing expense. Principal and interest are only part of it. Include property taxes, homeowners insurance, mortgage insurance when applicable, HOA dues, and any flood insurance or special assessments. Utilities, repairs, and maintenance belong in your household budget even when they are not paid through the mortgage.

Illustrative example · not a loan quote

The mortgage payment is not the whole housing budget.

Suppose your estimated loan payment, taxes, insurance, and HOA dues total $3,300 a month. If you also set aside $300 for maintenance, your planned housing outlay is $3,600 before utilities. That maintenance allowance is your planning choice—not a lender charge or a prediction of actual repair costs.

Down payment and cash to close are different numbers.

The down payment is the portion of the purchase price you contribute rather than borrow through the first mortgage. Cash to close also reflects closing costs, prepaids, escrow funding, deposits already paid, and allowable credits. Keep a separate cushion for moving and the unexpected.

Putting more down can reduce the loan balance and may change pricing or mortgage insurance. Putting less down can preserve savings. The right comparison looks at both the payment and the cash left in your accounts after closing—not just the lowest possible down payment.

Prepaids & escrowsItems such as prepaid interest, insurance, and tax reservesTiming and amounts; these are distinct from lender fees
Deposits & creditsAmounts already paid or credited toward the transactionAvoid counting earnest money twice; credits have restrictions

Some financing paths allow a down payment below 20%. Conventional private mortgage insurance may apply with a smaller down payment; FHA has a different mortgage insurance structure. VA and USDA have their own eligibility and fee rules. Assistance may be a repayable loan rather than a grant. We’ll compare the full combination.

Choose a loan around your situation.

Fixed-rate and adjustable-rate structures deserve their own comparison. A fixed principal-and-interest payment offers predictability, while an ARM introduces future rate and payment changes after its initial period. Never rely on a future refinance to make a payment affordable.

What to gather for a preapproval review.

The document list depends on your income sources, assets, and loan program. A common starting point is:

  • Recent pay statements and W-2s, or the requested self-employment records.
  • Account statements documenting down payment funds and reserves.
  • Identification and authorization for the relevant application and credit steps.
  • Information about current mortgages, other debts, and any property you plan to keep.
  • Retirement, rental, bonus, commission, gift, or other income and asset documentation as applicable.

Use the secure application and approved document channel for sensitive records. Do not put Social Security numbers, bank statements, or identity documents in the quote inquiry. Documents support underwriting; they are not a condition for receiving a Loan Estimate once the information that triggers it has been provided.

From the first conversation to closing.

  1. Set the plan

    Review your budget, cash available, timeline, and intended occupancy.

  2. Complete the application and preapproval review

    Provide the requested information and review any conditions. A preapproval is not a final approval or a guarantee about a specific property.

  3. Find the home and compare terms

    Once the property and loan details are known, review the Loan Estimate, rate-lock terms, and cash needed. Tell me about any purchase-contract deadlines.

  4. Work through underwriting

    The lender reviews your finances and property. Respond to conditions and discuss job, credit, or large asset changes before making them.

  5. Review closing documents and funding

    Compare final terms with earlier disclosures, resolve questions, and verify funds instructions through a trusted contact before sending money.

Common questions

Do I need 20% down?

Not necessarily. Down payment requirements depend on the program, borrower, and property. Compare the full payment, mortgage insurance or program fees, closing costs, and the cash you retain.

Does preapproval guarantee the loan?

No. Final approval depends on underwriting, property review, applicable conditions, and your financial situation remaining acceptable through closing.

Should I pay points to get a lower rate?

Compare the extra upfront cost with the benefit over the time you realistically expect to keep the loan. A lower rate is not automatically the least expensive choice.

Can I buy before selling my current home?

Possibly, depending on qualification and available funds. Review both housing obligations, the source of your down payment, and the risk of a longer-than-expected overlap.
