I am looking for hard money lenders so if anyone has any tips, I'd appreciate it. 

It's from 1970 and has a tenant there for 3 years already that plans to stay.I appreciate any tip on that.

That is kind of a background my main question is, does anyone have any knowledgable tips for someone just starting out in the industry or is anyone willing to have a conversation to share knowledge/experience it would be hugely appreciated. 

I've been advised to set up separate LLCs for international investments and would like additional tips/advice from individuals who have done this already. 

I would go for TIPs.

Also - any tips on regulation regarding doing work to siding/porches which have tenants in the property?

Reynolds Jr the classic real estate investor book of all time was written (first version) in 1959, is NOT about wholesaling, and contains none of the latest tricks, fads or improbable tactics.However, it is the absolute BEST primer for anyone thinking of entering the residential or small commercial real estate arena.

Any do's and don't you have learned or any tips you have for someone thinking about investing and possibly house hacking in the area.Thank you in advance!

Thus, my question -- is there anything out there at a medium to high level that just cuts to the chase and talks about such things and give tips and suggestions on best practices, do this before doing that etc ? 

Minor interpersonal tip, but a piece of advice I heard online that maybe(?)
