You can do this yourself but be sure you document when and how the form was delivered.

What documentation do I need in writing from bank that verifies that they are done with the loan and fees and won't bother me?

Your goal is to get the tenant to do as much clean up as possible so you don't have to.Buy the Nolo California Landlord's guide:http://www.nolo.com/products/the-california-landlords-law-book-lbrt.htmlYou should have a document signed by the tenant listing the condition of the apartment upon move in.

So I bought a condo about a month and a half ago...something has been bothering me though.The seller's agent somehow snuck in a $200 "cleaning reimbursement" on the HUD document that I don't recall ever agreeing to.

Further, a well documented check-in/check-out process with upfront expectations will help you from dealing with the headache college students that usually think the landlord is "out to get them" or just going to keep the security deposit.

Document when the tenant notified you of the problem and when you responded.

You can google around for partnership documents or better yet go to Amazon or your local library and read up.

There is also a portal that you can share with your tenant and you can store documents of your choice.  

At the point of signing loan documents, do I have a legal commitment to the lender or broker (I am concerned about major fee or cost increases)?

Do you send any type of formal document to renters if you are not going to renew a lease?
