I have a lease that states that the tenant can assign the lease with landlord's consent, landlord's consent not to be unreasonably withheld.

SMS marketing is 100% illegal without prior written opt in consent from the recipient. 

If that doesn't work, offer cash for keys....Hopefully, your lease has something in that states no one that is not on the lease can live at the house without landlords consent.

You must get written consent from the landlord (if you are not the landlord.)My confusion is – If I own a triplex or duplex in LA, & I'm living in one unit & I want to STR the other units out, then does it count as my primary residence? 

However, my current property manager only respond when she wants to talk (also very rude on the phone) and she automatically deducts all fees without my consent and permission. 

What you could do is take ownership in a revocable trust.

They just walk away, leaving the homeowner with $10.00 and his plans to move up in flames.I've seen others where wholesalers brag about making $50,000 as their (illegal) fee, meaning that they stole that much equity that rightly belongs to the seller.If a licensed agent mistreated a seller that way, the real estate commission in any state would issue discipline ranging from fines to license revocation. 

It reads "If all or any part of the property or any interest in the property is sold or transferred without lenders prior written consent lender may require immediate payment in full of all sums secured by this investment".....and so on.HOWEVER I have an "Adjustable Rate Rider" on my mortgage which I believe invalidates this clause.

In general, it feels a bit unfair to charge you a full new lease fee after 3 months, for allowing the tenant to break the lease w/o your approval/consent/knowledge.

@Karla SimmonsThere should be a specific section in your lease that addresses the consequences of adding a pet to your household without written consent. $250 cleaning fee?
