Frequently Asked Questions
How can I lower my LTV without paying extra principal?
Home price appreciation or substantial renovations can increase your home's appraised fair market value, thereby driving down your LTV ratio and allowing you to petition for early PMI removal via a new appraisal.
What is the difference between LTV and CLTV?
LTV measures only the primary first mortgage. Combined Loan-to-Value (CLTV) includes all liens secured by the property, including second mortgages and HELOCs.
