It's really all trial and error.

I did the same about two years ago and since then went thru many trials and tribulations to get this thing up and running to where I am right now (2 flops and 3 flips :-) I'm wrapping up my 5th flip and actively searching for my next project.

To sign up for the trial, simply LIKE the BiggerPockets Facebook Fan page and then click on our FB Fans Only tab.Once you click the Upgrade Before This $1 Trial Ends link, you'll be able to sign up for the trial offer.

I have both of them in the trial period right now, which isn't actually that helpful because I can't see how everything works out without connecting it to current tenants (and I don't want to have them switch from service to service).

The real money comes from 1) up sells....and 2) people paying them to fill their CRM with leads and weed out the cream of the crap leads on a "30 day free trial basis", after which they will cherry pick and flip after you cancel your membership.

If you're going part time I'd say limit it to a 3-6 month trial to see if you like the work before quitting your job - it sounds like you have some savings and investments, so rather than be mediocre and stretched thin, it would be better to do it fully or not at all. 

I just did my trial and error and eventually found someone desperate to sell.

You don't get to choose and scheduling repairs can sometimes be a trial.

I just learned how to navigate the State of Indiana, trial and appellate court case system.

Damages that they tried to remediate a couple of days before trial and haven't paid me for 7 months.
