Definition: The term mortgage 70% loan is a type of mortgage that requires a minimum 70% down payment from the borrower, which means that the lender provides only 30% of the total amount to be borrowed. In most cases, this means that you will need to have at least $50,000 in your own funds for the entire loan. The terms and conditions of the mortgage are designed to make it easier for borrowers to qualify for loans with lower down payments. This is often achieved through the use of "HARP" programs or other types of financial assistance that can help reduce the amount of money a borrower needs to pay out in monthly installments. Overall, the 70% loan is typically used as an alternative to a conventional mortgage, which requires higher down payment requirements and may have more restrictions on how much you can borrow.
