CLTV, also know as Closing Loan to Value, is the percentage of how much a house is worth compared to how much is owed on all mortgages on the property.
Example: House is worth $300,000 and 1st mortgage balance is $130,000 and second mortgage balance is $80,000 (total of mortgages is 130k + 80k = 210k)
= 70% CLTVA loan that is 100% CLTV means that you owe the same amount that the home is worth - you have no equity.
Many times you will need to do a second mortgage at a different bank than the first, as to avoid a conflict - due to Combined Loan to Value (CLTV) guideline restrictions on the first mortgage that is also financed by the same bank.
CLTV is also referred to as combined loan to value and is used by lenders to figure the overal risk of a loan. The higher the combined loan amount compared to the properties value will affect what programs and rates you will qualify for.
