Newbie Question-Does having a tenant affect a wholesale deal?

[Barclay Hallowell]

Looking at my very first inquiry from my very first online ad. The seller is "quietly" motivated and wants to sell a house that he rents out. It was his first house and now he has the property he lives in too. The 2 mortgages are affecting his credit and he wants to unload the first house.

In all my researching of wholesaling I've yet to find out how a tenant affects the transaction. Does it even make a difference if the property to be wholesaled is currently a rental?

Any direction for this would be greatly appreciated! Thanks!
