In escrow, 2 extensions done and expiring soon and my loan just getting it done but its not coming together now the total isnt quite enough. lf l walk l lose deposit $7500. l dont want to walk.What are my options?

The security deposit is paid by the tenant.  

Their security deposit is $1,400 and they paid a $300 non-refundable pet fee."

When the lease is fulfilled, the security deposit will be returned to the LEASE SIGNERS, less any repair costs and unpaid charges.

His lease isn’t over till the end of Oct and clearly states that “If tenant vacates the premises before the date agreed upon in the lease, the tenant will forfeit deposit and will be responsible for rent until the end of the lease.”

They will often voluntarily come up with increased security deposits, easily accept month-to-month rental contracts, and find other ways to work with you.

I would want some major security deposit on file - maybe 6 months rent (personally), and / or possibly have them carry an insurance policy with you as the named insured for a descent value for any damages, etc - with the policy specifically written for the type of business they are actually running.

They'll ask for the last 2 months worth of bank statements and they usually won't want to see a large deposit in there coming from borrowed funds.

I was also expecting the deposit payment from the tenant that signed the lease for the other property.

This written confirmation will give you peace of mind knowing that the loan was paid each month, and it also lets you know several months in advance if you are going to have problems because the buyer isn't paying and is therefore depleting the escrow account.And lastly, hang onto your 10k deposit and keep it handy.
