Is this a SCAM? Lease option sub-let

[Lesley Resnick]

I have a 2 properties for sale, see market place.  I have gotten 4 phone calls this week from people who want to lease my property with an option and sub-let it?  None of them are local or know the area.  They said they would pay market rent and will cover management fees and maintenance.  I could set my price for the sale option.

Is this a new strategy I have not heard-of or is it a SCAM?

If true, it is interesting since they guaranty my rent and maintenance.  There is no room to mark it up since the rent and option are at market.  It is not clear how they are making money and-my best assessment is they are losing each month?  Which makes me think it is a scam
