REFINANCE CALCULATOR LEGAL DESCRIPTION & DISCLAIMER: This tool acts strictly as an informational financial model estimating structural modifications to loan parameters based on basic interest variances. Projections calculate Principal and Interest (P&I) differences only; tax assessment escrows, transactional title lines, or property-specific structural insurance premiums are excluded from immediate savings computations. Upfront closing costs are estimated at a baseline ratio of 2% of total capitalization balance. Actual underwriting processing, transaction pricing, or locked rate qualification requirements remain strictly contingent upon manual application filing and physical asset appraisal clearances.
