How would you doorknock this neighbor?

[Anthony L Amos Jr]

I was sent a home by a wholesaler that I'm interested in purchasing. While doing my due diligence I checked the county auditor site to cross reference the property information. Low and behold the property is owned by someone in my subdivision that I do not know at all. I will not go over the wholesaler if I purchase this property but I would like to get to know my investor neighbors. Would you doorknock and tell them this, send a handwritten letter, walk the dogs by and just start general convo, like it was not planned :), or something else? If you were to doorknock what would you say? 

I plan on sending christmas mailers to my subdivision this year
