Seller Disclosure of Current Tenants Rents

[Thomas Fawcett]

Hey guys, This is my first post! I love BiggerPockets and thank you all for this great community!! My wife and I are looking at a FSBO triplex. The numbers look good but I will be inheriting 3 tenants. The rents look a little high for the area and I am wondering if there is a way to ensure the disclosed rent is accurate? Can I legally get the signed leases before closing? What should we do to make sure things are in place legally when inheriting tenants. Thanks!
