After reading it’s a clear 100% anonymous answer(at least in the replies) that it is never too young and that most wish they started earlier.

So try living their anonymously until you decide whether or not you like this business.Landlords can and will get abused by their residents both physically and financially.

I also suggest a drive-by so they are not unpleasantly surprised by the neighborhood when they to the showing, and just keep on driving by anonymously as I wait outside.

Both my CPA and attorney have suggested that for real estate on your own (ie not a partnership) that single member LLC's don't do you a ton of good -- although you are able to anonymize ownership by using a registered agent if that's important.  

I've been careful in what I post so far, but it would better if the site allowed for more anonymous posting, or if the posts were not googleable.

Think about the best way to implement asset protection, LLCs for isolation, Trusts for anonymity, insurance, mortgages/equity stripping, taxation, etc -all or some may play into your strategy.

We went with Manager Managed to help with anonymity of the LLC ownership, and the ability to make Manager changes without changing ownership. 

.- If you're structuring for anonymity, use WY as a base LLC. 

There is no reason to accept these risks.Lending is a business based on relationships, not online anonymity.

BP has a good high-level comparison here https://www.biggerpockets.com/...We're using LLCs, though, in addition to the asset protection (and anonymity via a land trust), we also are building a family trust for our kids so we can keep the government out of our business ;) so the LLC brings a lot of benefits for that.
