Reaching out to absentee home owner to sell

[Kevin Leppink]

I recently came across a problem property I would like to purchase. I was at a friends house and decided to drive by my childhood home. The grass was extremely overgrown, 3 windows boarded up, weeds 5 feet long coming through the cracks in the driveway, and numerous aesthetic issues. I had my agent look up the property owners and found out it’s the same people who purchased the home from my parents back in 1999. But she also discovered they don’t live there anymore(obviously) and they live in a nice new home in sandy. I also found an old MLS that expired 185 days ago that had the house listed for about 30,000 less than houses around it at the time. I would like to purchase this home and flip it, and I would not tell them it was my childhood home. My question is what would the best way to contact them about selling be? I have no phone number just their physical address of the new Home. Any answers would help me greatly because I would love for this to be my first deal, just a little stuck! Thank you
