Ask if there are any any additional fees for maintenance, advertising, evictions, etc... and make sure they are outlined in the agreement.

When you are performing maintenance requests the amount of notice you have to give is outlined in the lease.

For residential lending you'll see that these rules pretty much out line or lay the foundation for what is referred to as "prudent lending practices".Your comment as to seller financing brought me here. 

Also stress that this will only hurt the tenants because you will have to raise their rents a corresponding amount accompanied with a letter outlining who at city hall is responsible with he and his superiors direct line.

Isn't what he outlined basically what you do when doing "comps" - Find a property of interest, and see what houses in that subdivision or zip code have sold for?

I am not sure what the new loan will look like, i.e. will it be a 40 year loan, etc. the interest rates for the loan were outlined in what I read and will fall between 2% and the fully indexed amortizing original contract rate or the Freddie Mac primary mortgage market survey rate for a 30 year fixed rate.

He mentioned that this could be a negotiating tool to help outline your terms.

Well for starters you should always get a copy of the lease, you have no position to argue if you don't.The lease will outline who has the right to enter and for what reasons.

I'd drag out the letter that outlined the work and remind him what he agreed to.

If a person/tenant wants to leave a lease nor a leash will hold them. its risky because if you have no written lease, the tenants only obligations are to abide by state laws. a written lease outlines what can and cannot be done in your property and reduces liability. it is likely you are confusing the term written lease with term lease. a written lease can be month to month or term.
