What to do with existing tenants.

[Mark White]

Hey BP community I hope everyone had a good thanksgiving. 

I have been looking at properties in Bridgeport and surrounding areas and I think I've been getting better because in the past month and a half every time I saved a property on Realtor.com it goes under contract soon after. Or maybe the market is still hot and it's still a seller's market, either way, I see another property that I like and I think it's a good deal the only problem is there are tenants. 2 are on a month to month and one lease expires in May. I want to upgrade the properties and bring the properties to market rates. What's the best way to proceed?
