Most of the similar scams I've seen don't involve entering and showing the property, or being even anywhere near it. A common style is to post a duplicated listing on Craigslist (it may be a house currently on the market, but often is an inactive listing on Zillow - they just need an address and matching photos) with a story written in a style that would be familiar to scam aficionados. The owner is a god-fearing good person who just wants their house to be safe while they are overseas on missionary work or in the military, and they're willing to rent it to the right people for a generous below market rate. Kindly do this-or-that, god bless you, etc. They request a sum of money, making it enticing by naming a rate 3/4 of what would be going rent for the property, and say they'll mail the key.
