You, or your agent, will review the estoppel with the tenant, allowing the tenant to amend or append to the content.  

As an Escrow Officer, I can tell you that any money "held" in escrow is not likely to be auto-released without a really well written CAR Addendum and Escrow Amendment.

To do this you will need to make an "amendment" to the original agreement  which will give you permission to assign and sublet.Once you have received this approval, you can assign your contract or sublet to a tenant buyer for a higher cost and purchase price. 

Lease documents in order.. and policy, house rules written in place..now is the time to have it all set so you don't have to add amendments later.When posting your ad be specific,, not vague,, if you only want 1 person,, then list 1 br apartment occupancy limit 1 person,, list your rent criteria.. this is pre screening your tenant, and go over it again when they set an appointment up so your not wasting your time.. 

Never having engaged in this sort of ask, any thoughts on likelihood or tactics to get it amended?

I'm typing up my first lease agreement and adding in a few amendments I've heard on bigger podcast to a standard lease I got from a mentor.

I'd get a corrected disposition done and make it realistic and send out an amended form to the tenant..

I put together an amendment to their lease, "deferring" September and then increasing their rent through the rest of the term.

If the 84 months is correct I missed a deduction for my 2016 return and will need her to amend them also.

Good advice on prepping the house for market is valuable, and then the first time you have a contract dispute or have to negotiate a repair amendment, that help will be valuable.
