Understanding Loan-to-Value (LTV) Ratio
The Loan-to-Value (LTV) ratio is a financial metric used by lenders to assess the risk associated with a mortgage loan. It compares the loan amount to the appraised value of the property being purchased or refinanced. The formula for LTV is straightforward:
LTV Ratio = (Loan Amount / Property Value) * 100
For example, if you are borrowing $200,000 for a property valued at $250,000, your LTV ratio would be:
LTV = ($200,000 / $250,000) * 100 = 80%
Why is LTV important?
- Risk Assessment: A lower LTV generally indicates a lower risk for the lender, as the borrower has a larger equity stake in the property.
- Loan Approval: Lenders often have maximum LTV thresholds. Exceeding these can make loan approval more difficult or impossible.
- Interest Rates: Higher LTV ratios may result in higher interest rates because of the increased risk to the lender.
- Private Mortgage Insurance (PMI): If your LTV is above 80% on a conventional loan, you will likely be required to pay PMI. PMI protects the lender if you default on the loan.
- Refinancing: When refinancing, a lower LTV can help you secure better terms and potentially avoid PMI.
Understanding your LTV ratio is crucial when buying a home or considering a refinance. It directly impacts loan approval, interest rates, and potential additional costs like PMI.

} else if (ltv <= 90) {

} else {
