Off market deals? How to approach owner?

[Peter Kopchik]

I have a house nextdoor to my multifamily house where I also live, that is possibly a good off market deal. The owners are elderly, husband died earlier this year. House is in blight conditions. How do I go about contacting seller? I don't have a lot of money or cash flow for cash offers. Also another owner in the area recently had one single family house on the market with the option to buy her neighboring single family home for a slight discount if you buy both. The one was contingent, now off market. How can I approach them and find out what the status is and what should my angle be?
