The Loan-to-Value (LTV) ratio is a crucial metric used by lenders to assess the risk of a mortgage loan. It compares the amount you're borrowing to the appraised value of the property you intend to purchase. The formula is straightforward:
A lower LTV ratio generally indicates a lower risk for the lender, which can translate into more favorable interest rates and terms for the borrower. Conversely, a higher LTV ratio might require private mortgage insurance (PMI) or lead to higher interest rates. Understanding your LTV can help you negotiate better loan terms and prepare for the costs associated with different LTV scenarios.

} else if (ltvPercentage <= 95) {
