Geez...I would notify the (female) tenant that she is in breach of contract.

You can't resolve the issue unless you pay off the loan, the bank sends the property into foreclosure and your original seller sues you for breach of contract and ruining his credit. 

Breach of contract makes you liable for damages, but isn't a criminal act. 

Additionally, I don't have the time to sift through all the legal jargon and pinpoint where they’ve breached the contract, so it's worth having a lawyer review it in my situation.

Document lease breaches ASAP and move to terminate with your attorney in the loop. 

@Bob Asad at our bank, we have an escrow account for security deposits, it is set up with sub-accounts for each tenant with their security deposit amount and their SSN.

Hey @Thanh Lu, we don't do much direct bookings but we do have a $500 security deposit.

Nothing you mention is "ordinary" and you should charge for all of it. dodged a bullet there thats a very good price take it from the security deposit and call yourself lucky. 

I just had tenants move out of my investment property (duplex) without paying for the last month's rent, and the damage they inflicted onto the property exceeds their security deposit amount.

IN these cases they took title sub to from the sellers .. ( but in the case your describing its the same thing you have a senior note as most investors will want security) they then sold on contract to buyers with small down payments and credit challenged or income challenged and they did about 30 of these in a year or so.. worked hard at it..
