You could call the bank, with their permission, you might also be able to run their credit, I believe it will tell you if they have missed payments, it might not give you the current status, but if they tell you they never missed a payment and the credit report begs to differ that would be useful information.

I would draft my own contract or have my attorney draft the contract or modify the one provided by the contractor to include the following:Detailed scope of work, start date and completion date with penalties for exceeding the completion date without prior written permission.
