LTV means Loan To Value and represents the ratio between the loan amount and the value of the collateral. The maximum LTV offered to the borrower is 75%.
The projected LTV represents an LTV figure that Estateguru's team is willing to offer for this particular project as a maximum. This indicates that within the upcoming stages of the loan the LTV of the loan might increase up to the projected LTV figure.
