I have the property and a price I like, How do I get it under contract?

[Luke Swab]

So I currently have 6 SHF that I rent in Lansing Michigan. There is a distressed house on the street that has been vacant for years that I want to purchase. It's not listed for sale. I looked up the owner and drove to their house 20 minutes away. I said who I was and I would like to buy the house. It's her dad's house who passed away a year ago. The house is full of his stuff. She said she was going to sell it for $17,000 but needed a few months to get the stuff out. At the time I didn't have the money. Now, 3 months later I have the cash to buy and do the renovation. This is a great deal for my neighborhood and I don't want to screw it up. I want to be professional and know what I'm doing when I approach her this week. Can you please walk me through the process and what purchase agreement do I need? This is my first home buying outside of the MLS so I'm green with this more creative house lead.

Thanks,

Luke
