I looked at all my rents, realized I'm about 20-30% below marketSo thanks to http://www.tenantstogether.com and other money grab socialist groups spending on this Prop 10 rent control prop (which will lessen affordable housing)  I'm raising all my rents. 

One is run by Tom Zeeb but I don't know the name of the group.

Don't wait to join a group in your area. 

Would I enter each cabin separately into the Rental Property calculator, or would it make more sense to group them together?

Turns out I didn't know what I didn't know.Yeah, the local Investment groups are wonderful I'm learning a lot from them.

Consider finding your local real estate investment group.

hello and welcome Lots of questions....I say find a local REI Group and go and speak to them about all of your concerns. 

Along with going to these meet ups and shaking hands and networking you need to join real estate groups on Facebook and stay active om there as well.

You could start a meetup group....surely you are not the only one who is unavailable mid-week. 

It's worth going if you've never been to one before, but like I said, leave the credit cards at home.Enjoy the pumped up, enthusiastic atmosphere they'll provide, but instead of signing up for a coaching program try a different mission: Collect business cards or contact information for at least 5 people close to you (where it would be convenient for both of you to get together every 2-4 weeks), who are either at your level or one notch above.Then after the event, make it your mission to have coffee/tea/whatever with each of those people, either individually or as a group.
