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.

Sellers may struggle to mentally shift from "owner" to "tenant," which can create challenges with boundaries and property care.Security Deposit:If you’re doing a temporary leaseback, be sure to collect a substantial security deposit to cover potential damages and ensure they vacate on time.

Each jurisdiction is different, but typically include a substantial deposit due same day up to full price deposited that day. 

All deposits and rents are collected through RentRedi.

Set up a Joint account with the seller so you can make deposits to continue the automatic payments to the lender until you refinance the property.Thanks,Dustin

Making additional payments or taking a shorter term are just depositing more into that savings account (it's not like the property appreciates more by paying down the loan). 

However, I have offered two thingsA)  Higher deposit -  this way the owner's fears are alleviated somewhatB)  Property management - offer the owner that you will essentially property manage the property for them.     

That would be called the BRRRR strategy - there is endless info on that strategy here and on the podcasts and in the BP bookstore.

I lost another $1000 in inspection fees but should get back $2000 earnest money deposit.
