    About the Mortgage Recast Calculator

    A Mortgage Recast (or re-amortization) is the hidden alternative to refinancing. Instead of getting a new loan, your lender simply re-calculates your monthly payments based on a lower balance.

    This is ideal for homeowners who come into a large amount of cash (from an inheritance, bonus, or sale of a prior home) and want to increase their monthly cashflow immediately.

    Features of the Mortgage Recast Calculator

    Includes lender recast fees ($200-$500) in the ROI calculation.

    The Refinance Alternative

    Outcome

    They recasted with a $60k inheritance for $250.

    Advantages and Risks

    Advantages

    • Immediate monthly budget relief
    • No credit check or appraisal required

    Disadvantages & Risks

    • Requires significant upfront cash
    • Not offered by all lenders (e.g. FHA/VA)

    Risks & Mitigation Strategies

    Comprehensive Guide to Mortgage Recast Calculator

    Refinance vs. Recast

    Refinancing replaces your loan. Recasting re-calculates it. If your current rate is lower than market rates, always recast. If market rates are lower, consider refinancing.

    Key Takeaways

    • Recasting lowers your required monthly payment; Principal reduction does not.
    • It requires a lump sum payment (usually $5,000 to $10,000 minimum).
    • You keep your existing interest rate and original payoff date.
