I have asked for the written consent ...

Outdoor cultivation on the property requires prior written consent.

@Dan Tsunekawa ,  No residential lender can do this type of financing, however, if you move the property in a revocable trust whose beneficiary is your LLC, then he can do the loan!

The permit you apply for will require a written consent from property owner. 

I made it clear to "B" that the property is titled under both "W" and "H", but he is very adamant that their Attorney "A" said that "W" can sell the property without consent from "H".

In their website they want all my info (and of course my consent to send me all kind of things) before even giving out their contact info.

The police and the courts would most likely laugh at them assuming your lease prohibits satellite dishes or modifications without your consent.

My opinion is ultimately the PM company should be held liable to make sure this vendor gets paid.The PM agreement states: (21) hire contractors to repair, maintain, redecorate, or alter the Property provided that Broker does not expend more than $ for any single repair, maintenance item, redecoration, or alteration without Owner’s consent; Leasing & Management Agreement concerning: (TAR-2201) 6-1-10 Initialed for Identification by: Broker/Associate and Owner , Page 3 of 11 (22) hire contractors to make emergency repairs to the Property without regard to the expense limitation in Paragraph 4A(21) that Broker determines are necessary to protect the Property or the health or safety of an ordinary tenant;3) Should/Could the vendor file a mechanics lien at this point?

They may also freak out - in which case - the law regards silence as consent. 

You have probably signed paperwork that they can list your house for 6 months, so unless you get her / the brokers consent, you can’t withdraw the listing.
