My tenants are not allowed to alter anything without my written authorization.  

Write in whatever you want (ie tenant can move out anytime with no penalty with X days notice).If you're not comfortable altering or adding lease language for that, like Wayne Brooks said, just do a mo-to-mo or week-to-week lease.Curious though, from an owners perspective, why would you want to give the tenant an easy out?

I was just thinking that  stress and hormones can alter the way people would normally act. 

We told realtor we wanted that removed and she said that we cannot alter the bank’s addendums It stated that it was per HUD guidelines but the property was not listed as HUD sale.

If there is an alteration then it needs a permit to substantiate.In general 3/2 or 2/1.5 with similar gla sf can both be used as a comparable properties.

You can alter them as you see fit, as long as it doesn't go against signed leases.

*FAS = FUNDAMENTALLY ALTER the nature of SERVICES providedWhy has no one been able to turn down ESA requests based on the wording of the actual FHA law?

And after I went to the building and safety office twice and some plan alterations, I got the building permit. 

I altered the co-signer agreement to require no performance fee.
