There is so much BAD information online about LLC's and real estate investments its disgusting.

@Oli HarpsTo manage your Oakland 4-plex effectively, stay informed about the local market, build local connections, conduct thorough tenant screening, consider value-add opportunities, decide whether to self-manage or hire a property management company, network with local investors, plan for growth through scaling your portfolio, explore financing options, and stay informed about the local market through online communities and resources.

Check the in person events and meetups in your local area, our online community is full of knowledge and folks willing to share and still nothing replaces the opportunity to interact IRL, you never know who you will meet and where that can take you on your REI journey.

One platform I highly recommend is Baselane.
