The proposed term is longer than the remaining term. A lower monthly payment does not necessarily mean lower total borrowing cost. Extending repayment can increase the time interest is paid.

- Planning estimates are not a loan offer, lender quote, settlement statement or program-eligibility decision.
- This estimate assumes lender-paid loan-originator compensation, with $0 charged to the borrower for that compensation. It adds no borrower closing cost or APR finance charge. Other origination and lender fees may still apply.
- Zero discount points, lender credits and seller credits are hypothetical defaults unless a known amount is entered. The entered scenario rate is not a quote available at zero points.
- Planning timing: one hypothetical advance on the first day of a month, first payment on the first day of the following month and regular fixed-rate, fully amortizing monthly payments. Your buying timeframe is not a contractual closing date.
- Separate odd-day prepaid interest is $0 only in this regular-period model. Actual closing timing can change prepaid interest and cash needed; actual-date APR is unsupported.
- Estimated initial escrow allowance: four monthly tax amounts plus two monthly homeowners-insurance amounts, with no extra cushion. Actual deposit depends on bill dates and lender/servicer analysis; this is not an actual escrow analysis.
- Unknown contract-specific property-tax proration is not included. This is not a verified $0 settlement adjustment; actual contract terms can change cash needed.
- The versioned NEXA reference worksheet supplies hypothetical borrower-paid planning fees; actual charges vary by transaction and provider.
- The optional owner's title policy is omitted by default. Additional unknown or unclassified charges cannot use real-estate exclusions without review.
- Unknown costs are not zero. The known-cost subtotal is not a complete closing-cost estimate.
- Refinance does not automatically charge a new annual homeowners premium. New escrow uses the stated planning allowance; any old escrow refund is not assumed available as closing-day funds. Actual renewal premiums and payoff interest need settlement information.
- Financed costs and amounts already paid are portions of the same cost, counted only once.
- Credits and deposits are included only when entered; gifts and assistance explain the source of remaining cash rather than reducing transaction costs.
- Published program schedules and disclosed hypothetical assumptions are used only within their supported scope. No actual closing date, VA exemption, extra escrow cushion or eligibility approval is inferred.
- Proposed refinance costs and APR belong only to the new loan. Payoff and cash-out proceeds are separate from costs and cash contributed at closing; existing-loan APR is not reconstructed.
