• Is there a ceiling on payment adjustments?
• Can the term of the loan be extended?
• What is the maximum rate that can be charged over the life of the loan?
• Is there any potential for negative amortization?

Is there a pre-payment penalty clause?

• Will the lender require mortgage insurance?
• Is the loan serviced locally or is the servicing sold?
