You will just need your basic LLC paperwork (Articles, Operating Agreement with any amendments/addendums, and an EIN letter).It seems like you are already going the route of having an LLC for each property, though, which helps keep all the assets separated.

They could just have their seller sign an assignable contract (between seller and agent) instead of a listing agreement and amend the sales price at closing to reflect the agreed upon price with the end buyer.

When assignments have not been recorded and served upon the tax collector, the tax collector and the municipality shall be held harmless for the payment of any redemption amounts to the holder of the tax sale certificate as appears on the records of the tax collector.L.1943,c.149,s.1; amended 1997, c.190, s.11.

"CONSUMER AND GOVERNMENTAL AFFAIRS BUREAU ANNOUNCES COMPLIANCE DATE FOR AMENDED TELEPHONE CONSUMER PROTECTION ACT RULES ON PRERECORDED CALLS"A2P falls within this group, and compliance is required as of July 20, 2023.I use OOMA, which is P2P, with a separate virtual number.

(1) Are there any new clauses or amendments you need to make in your leases? 

Both us and the buyer have called the city to try and make amends and get this compliance plan set, but this is the first time I've gotten a letter like this, and it freaked me out a bit.  

I am surprised your agent is not providing you with ones. estoppel certificates are needed in addition to the lease agreements, because it tells you e.g. which personal property belongs to the landlord or tenant, whether the rent has been paid, whether there are any amendments to the lease, etc. 

Some have standard leasing forms and you can add amendments. 

I guess I should amend my post to include 'gals' along with guys. 

(operative) Section 65852.2 of the Government Code is amended to read:65852.2.
