SWAT team just raided a nearby house, how do I buy it?

[Matthieu Miser]

So I'm new to the game (meaning I haven't done my first deal yet) and I'm looking to rehab/wholesale deals in the Provo, Utah market.  I come from a sales background so I'm used to trying to get complete strangers to do business with me.  However, I would like your opinions on the best way to approach this deal.

In other words, these are my main questions about the following deal:

- What information should I gather before making the first call to the owners of the home?

- Have you got any advice on the best way to approach the potential sellers?

- Are there any pitfalls I should watch out for in this particular deal?

THE DEAL (this is where the SWAT team comes in):

So the house I'm looking at is a single-story, single-family home in a B/B+ neigborhood with 4 bedrooms, 2 bathrooms, and 1700 square feet.  It was owned by a family I knew who sold the home to a woman in her 50s.  The woman died of cancer 3 weeks after moving in (this was a few months ago).  Ever since her death it hasn't looked like anyone is taking care of the home.  The grass is overgrown with a ton of weeds in a fairly clean-cut neighborhood.  

The property really caught my attention a couple days ago when about 15 police cars and a bunch of dudes with assault rifles showed up and raided the home.  I'm guessing that if the property wasn't distressed before, it is now.

I haven't got much info on who currently owns the home.  I did a reverse address lookup on whitepages.com and found what I assume are the deceased owner's kids.  The Zillow Zestimate for the home is $325,000.

So, like I said above, I'm hoping to get some advice on what info I need to gather before cold-calling the possible owners, as well as any pitfalls I should watch out for.

Thanks guys!
