I don't rent furnished and others may be able to point out where this is flawed, but I would consider renting the furniture SEPARATE of the unit because that may allow you to collect a deposit on the furniture.

Would you take an escrow account with a deposit?

Leases are signed electronically (esign.com), and I set them up with RentRedi for deposit, cleaning fee, and rent payments.

Renter's Insurance is a cheap date for the tenant; it protects their security deposit and assets. 

Withholding the entire amount of the security deposit doesn’t even cover the costs incurred. 

You identify the problem (lack of deposit) during your inspection phase, then hit them with an objection that requires them to pay you a deposit at closing.

I used a private lendor to fund the re-hab (cash) and owner financed the purchase price (minus down payment) I have a bank account linked to Stessa and I see the cash deposit in the transaction tab. 

She can also do postdated cheques, so you can deposit them on the 1st of each month. 

New tenant must go through complete vetting, sign the lease, pay security deposit and rent, and move in, prior to the referring tenant getting their $100.

Most work with us, some do not.Be careful also as they may tell you to keep their security deposit as last month's rent.
