While it still has to make sense as an investment of resources, programs like these could sweeten the deal.  

But what about sweetening the deal by offering to maybe doubling or tripling their equity in addition to taking over the loan?

The monthly costs of this sweetener should be viewed with tenant retention/attraction in mind.

It is insanely profitable: 1) I find and place a vacant single tenant commercial property under contract with a 45 day due diligence (to inspect the property with no obligation to purchase it) I need only $5,000 for Earnest Money Deposit that's refundable 2) I contact a list I created of 4000 national tenants (I follow a very specific system) and get one of them committed to lease the space for 10 or 15 years with a NNN lease (NNN means: Tenant pays the lease plus taxes, insurance and maintenance) and a corporate guarantee (lease is guaranteed for the duration and backed by their financing bank like Wells Fargo) and I would offer them some money to offset some of their TI (Tenant Improvement for the location) I can offer up to $100,000 to sweeten the deal and get an LOI to lease from the National Tenant 3) I take the cash I have (in your example $1,000,000) and buy the property all cash (say for example $900,000 and $100,000 additional will be going toward the rehabilitation of the commercial space for the tenant as agreed) 4) After I close on the property and the Tenant signs the 10 or 15 year lease I go to the bank and get the property appraised It usually appraises at 1.5X what I purchased it for when it was vacant.

You might use that equity on a purchase money loan to sweeten the deal for a lender who doesn't do cash out refis on condos (blanket loan) or assign it to a seller financed transaction as additional collateral. 

They may do it because they realize you are attempting to settle your accounts, and it may sweeten the deal on both ends to make those payments via direct deposit.

If she tries to stay after August 31st, let her know that you will be forced to evict her and it will negatively impact her credit.If option 1 isn't sweet enough because the security deposit isn't large enough, you can always sweeten the deal with an extra $500 or whatever you see fit.

Throw in a sweetener if you like because it’s Mom.

In CA, opening your mouth can get you sued so might as well just shut up.If you have found the perfect place, did you sweeten the pot to seal the deal right there?

Outside of the agent stepping up and doing their job, you could always offer to come out of pocket to sweeten the pot.
