But electronic options don't normally work in those cases. 

I promise it beats trusting social media gods.Investor list nurturing requires consistent communication.

Plenty of publications and journals to read on this, along with books and other print media.

The reason I picked this one over others is due to the following:1) Its syncs with Google/GMail & Calendar, and it has several "killer addons" for Gmail & Chrome, which is where I have all of my current contact info. 2) It only costs $15 per month, but, I believe that they have recently increased their initial price to $25.3) It's one of the only CRMs that is heavily centered around social media.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

If you're willing to put the time, strategies like cold call, direct mail, door knock, PPC, social media might be worthwhile.

I require electronic payments or a check to be mailed.

Here's a link to social media post where I asked the property manager about it: https://www.facebook.com/share/p/mRVzr9w2QBQcR5ba/Also, if you think I'm overreacting or I'm wrong for inquiring, I'd love to hear it.

My idea was to set a date for an as is auction and put out signs, flyers, and social media ads for the auction the week leading up to it.

Social media can be a powerful tool, and then good old-fashioned door knocking for listings is a great way to drum up business as well!
