I'll take any and all advice any of you have, but the two things I'm looking for specifically are: what sites, services, and/or software you use and recommend for sceening and managing tenants? 

Quote from @Thu Pham: Great to hear you are finding a place and getting in touch with a possible Co-host..

There are a number of meetups in Sacramento and we have been coordinating the dates among hosts so that there is no overlap - I run the West Sacramento Meetup that @Ben Howard mentioned (we gather every 4th Tuesday of the month).Here is a list of meetups that we're in collaboration with (they are all based on an abundance mindset that we have here on BP)- 1st Tuesday - REI Connect @ Roseville Meetup (reach out to @Nicole Masters)- 3rd Tuesday - Investor Mixer @ Crawdads on the River- 3rd Thursday - Folsom Out of Bounds (dates may shift a bit)- 3rd or 4th Wednesday - Real Estate Round Table (CH Cafe & Grill) - they recently relaunched and stabilizing the schedule- 4th Tuesday - West Sacramento Real Estate MeetupI'm working on putting together an easy to access list that Sacramento investors can refer to.

You can also look at sites like auction.com, homepath.com and homesteps.com.

Hey Elizabeth, this is a great site to network.

We also have infrastructure in place at a build site for a 3rd unit on property.

There is a web site that lists all the section 8 housing, so people might be also be looking there. 

We can get your site up and running in a matter of days, with content and lead magnets included.I've also heard good things about their education for maximizing your marketing and website's potential.

This could include computer delays, the inability to reach the site, creating a late filing, and subsequent penalties.

Not a book, but Bill Faeth has a lot of free, good content on his site and YouTube videos.
