After my last 2 purchases, Clackamas county has sent a letter wanting to verify that the transaction was at arms-length (to properly assess I'm guessing).  

Do I need to send them an Adverse Action Letter?

The best deals are the ones you find/create yourself, but that means you have to put the time and work in to find/create them.Start with the neighborhoods around your house - do "driving for dollars" looking for vacant or derelict properties and send a letter or postcard to the owners offering to buy (to find the owners use RIPropInfo.com and the Assessor link for the town, then look the property up).

I constantly get yellow letters and the like.  

I thougt about half of this **** while I was writing this letter and some of it might be a little too tough.  

Hi @Tim Fishback I invest on South Broadway and I am three blocks off of Broadway near Yale.

I am wanting to send out a second round of direct marketing. Should I consider the Memorial Day Holiday when scheduling the send date?  I want it to get the most attention. Thanks for your thoughts!

The bidding went to 190k and there were at least 3 similar homes within a few blocks that were superior listed for 150-175k.

So I will only have wi-fi on my properties for the cameras since I can block all other access to the network from any device to the router it won't be hard at all. 

Most investors here do door knocking campaigns, yellow letter campaigns or foreclosures.
