Would once a month be enough of a check in frequency? 

@Matt Motil what frequency are you re-visiting the properties you're interested in?

@Ryan Billingsley I like the quote from Brandon Doyle in Realtor magazine, “Frequency is more important than reach.

Keep your ears open for BP meet-ups in Seattle, they happen with some frequency.  

However, depending on the class of property/tenant you might consider increasing the frequency.

I have come across the idea of offering free labor/partnership in exchange for mentoring, but to my understanding the frequency this occurs at is few and far between.)Best Wishes!

If your recorder/clerk/recorder of deeds has their data online, go to their website download all the deeds that were recorded within a certain time period (say six months).Then go on Excel and sort the names by frequency and you'll have all your entities sorted by transaction volume.

My hobbies change with embarrassing frequency, with gardening being my current obsession.

Looking for opinions on target group to mail to, frequency and total number of time should mail to same group.

I'd love to hear more about your mailing strategy (both in terms of how you position your offering as well as the frequency of following up).
