Hi, Brad,
Congratulations on starting your RE investing journey! Depending on where you live and how close you can find investment properties, certainly another condo could work.
You should also consider a duplex, if the deal makes financial sense. That's a reasonable step up and gives you a chance to develop some processes to manage your properties.
I'm a big believer if you want to scale up, that you've got to develop processes that help you efficiently manage properties. And if you document those processes, as you build your portfolio, you can get part time help up to speed more quickly so you can grow and work on finding good investment properties.
Next, investing as an LP in multifamily syndications can grow your savings, but it won't give you commercial real estate investing experience if you want to become an active investor.
For more active learning, look for a nearby meetup and attend a conference or two yearly hosted by the names we all see in the multifamily syndication space*. That way you'll find people who are active, get to know people who invest in your area and who you develop a relationship with. Volunteer to be part of a team to learn how they operate. And read books. There are lots of resources available.
Good luck!
