Be willing to sign an amendment to change to financed purchase.

And since his client only has a month left on his lease, there is no way you have the time or desire to execute a new amendment to his lease.So, his client will be under the existing lease, you will post his rental, and file in court as soon as you can in your location. 

I always thought listing agreements meant exclusivity no matter what the transaction was so it's good to know that it can easily be amended to place a tenant.

I am currently in escrow for a property in southern california, and we are having trouble with the loan because this year I had to file an amendment on my taxes, and the amendment is still pending, and could be pending for another 2-3 months as the IRS is very backed up at the moment. 

The contract was amended/changed - that tenant will not be responsible for July's rent because you released him from that obligation.

Am I on good legal standing to insist that the current tenant vacate the property by August 1st since the lease was amended (at the behest of the tenant) and agreed to in writing by both parties?

This Section shall not preclude amending this Restated Declaration during the term of its existence.”Also, in the section 752b of california condominium bill, there is a clause that reads:“Where several persons own condominiums, as defined in section 783 of the Civil Code, in a condominium project, as defined in section 1350 of the Civil Code, an action may be brought by one or more of such persons for partition thereof by sale of the entire project, as if the owners of all of the condominiums in such project -were tenants-in-common in the entire project in the same proportion as their interests in the common areas, provided, however, that a partition shall be made only upon the showing that … the project has been in existence in excess of 50 years, that it is obsolete and uneconomic, and that condominium owners holding in aggregate more than a 50 per cent interest in the common areas are opposed to repair or restoration of the project”Thank you in advance!
