Now in terms of the returns, when someone is actively engaged in real estate (eg., as a landlord or a flipper or anything else) their returns over time are higher versus being passive (e.g., through a syndication).

You are right about the property management bit in that three-families generally require more maintenance and upkeep vs. condos, but the returns are fare more superior. 

No you would not have 108% ROI you would have a 100% return of capital and the.

Are there other things that would be easy to get a good return on?

I built in an independent WIFI network so that the laptop can register my IP address while they work from the Philippines.I'm currently working on more training videos for them to have them doing more things, one of which include about 45k emails a month.I can literally be on vacation now and not stress a bit, I don't check my laptop every 2 seconds, I don't typically return emails or many calls at all.

One thing to bear in mind is that if you obtain a mortgage on your rental properties, then you will need to file a tax return for your IRA to report UDFI (Unrelated Debt Financed Income) tax. 

If you don't care about growing anymore or getting the most returns possible, then it is fine to leave it just in case every one of them has an issue at the same time.

Even if my offer isn't accepted or things don't work out for other reasons it's been a good exercise, as a newbie, trying to assess the costs and potential returns of the two different options.

Keep in mind that some, such as Internal Rate of Return (IRR), require advanced computer calculation.https://www.biggerpockets.com/blogs/8814/73755-18-essential-metrics-to-a-complete-real-estate-investment-analysisAs far as finding multifamily properties, you'd find them the same way you find a SFR, and there are many, many ways to source them:By building relationships and letting everyone know you're looking for houses and apartments:https://www.biggerpockets.com/blogs/8814/72664-35-relationships-to-help-you-find-more-houses-to-flip-or-wholesaleLooking for them on the internet:https://www.biggerpockets.com/blogs/8814/72016-55-resources-to-find-real-estate-deals-onlineand, of course, locating them offline:https://www.biggerpockets.com/blogs/8814/71506-27-ways-to-find-off-market-and-wholesale-real-estate-deals-offlineBest of luck!
