Tenant Looking to Purchase House

[Jonathan Yvon]

Hey Group, I am currently renting a single family house in the MA area. Our landlord is looking to sell the propoerty, its a single family 2-story house with an unfinished basement and second floor just has the framing. Second Floor is has no plumbing or electric installed what's so ever. What are some creative ways I can purchase the property? How can I use the unfinished 2nd floor to bring an advantage to the negotiate table?
