I am refinancing two properties with the same mortgage co. I am the landlord of five properties and have large deposits into my account each month. The mortgage co wants me to write these silly two line letters to verify the source of my deposits, which is always "RENT." They have my bank statements, but now want my deposit slips! They should just tell me they think the statements are fake! It's insulting!!! WHy do they need the deposit slips if they have the statements?
