landlord wanting to sell

[Chris Graf]

I got a call off my bandits signs from a landlord that has 2 3/1.5 houses side by side. He says that the tenets lease is up in the end of july. He wants me to give him a offer on them both. If we came up with a agreement on price. how would I put this under contract since the tenets are there till july. Would I put it under contracts now or wait till the tenets are gone in july?
