Except as otherwise required by law, all notices under this Commercial Lease from Landlord to Tenant shall be mailed by first class U.S. mail, postage pre-paid, to Tenant’s last known address, or e-mailed to the e-mail address provided by Tenant in the Terms and Conditions and shall be conclusively presumed to have been received by Tenant three (3) business days after mailing or emailing.

This doesn't allow you to pull additional cash out of the property (meaning you won't walking away with extra money in your pocket), but it could potentially cover the borrowed funds, financing of closing costs, prepaid items, and/or points. 

Then the purchase of the life estate or prepaid rent or however you choose to structure it washes out to you as good NOI.  

To do that, they would gross up the offer price to include their closing fees like prepaid taxes, bank fees, title fees, etc.

Not to brag (well, maybe a little), I was able to get the seller to cover all closing costs - which, with prepaid taxes and insurance came to $16,000.  

With that in mind, if you were to move out of the property after year 5 into a new primary residence, the thought is you basically pre-paid your rent for 5 years, now you have to decide if you're willing to eat the $1,000 loss every month (difference between $3,200 rent cost, and $4,200 mortgage cost) granted there is an expense recapture on the taxes and interest that can minimize the pain.

That is a lot of "pre-paid" incomeHow much of your own capital?

For emergency savings, consider pre-paid cards.

The security deposit and pre paid rents should be transferred to the buyer at settlement and should be on the ALTA closing documents.
