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?

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!

There is great mortgage math you should know and if you use this tip as a rule you will always know how your purchasing decisions affect your DTI, and why you should almost never get joint financing with your spouse ever again.Mortgage Math works like this. 

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 ? 

New windows, siding, roof, gutters, front and side porch, landscaping, electrical, plumbing, cabinets, granite countertops, HVAC, etc..

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