Question about Tenants before property is closed on

[Preston Humbard]

Just to provide some background my wife and I are going to be purchasing a condo and have a perspective close date of June 1st, 2018. We have signed a purchase agreement with the seller and got approval from the seller to advertise the property and also set up showings.

With that being said my question is what can we do if we have found tenants who meet minimum requirements and are interested in the property? I know a lease cannot be signed if we do not own the property but I also do want to risk losing the probable tenants. I also feel like just a verbal "yes we will rent from you" is also too risky because they could back out at the last minute.

Any advice on this would be greatly appreciated!!
