Here's some info that could help you secure a construction loan. Collateral or guarantees are additional forms of security you can provide the lender. If the business cannot repay its loan, the bank wants to know there is a second source of repayment. Assets such as equipment, buildings, accounts receivable, and in some cases, inventory, are considered possible sources of repayment if they are sold by the bank for cash. Both business and personal assets can be sources of collateral for a loan. A guarantee, on the other hand, is just that - someone else signs a guarantee document promising to repay the loan if you can't. Some lenders may require such a guarantee in addition to collateral as security for a loan.
