Personally, I am not a Detroit guy, just pointing out actual facts.

I have 7 doors personally and another 4 with a partner in a two member LLC.  

My personal investment philosophy would avoid leveraging my primary residence unless I had plenty of reserves to ensure I would be covered in that kind of situation.

Key differences for us include:- we JV with local person on our deals.

Is that based on an actual study or your personal experience?

Most agent wants to sell under my personal name and add my LLC name which is the beneficially of my land trust as a additional insured which do not make sense since the property title under the land trust.  

This person is eating up your time and sanity.

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

These are the best contacts, in my opinion, because I can find ways to add value to them.As my experience level changes, I keep an eye/ear out for specific types of contacts. 

However, the person who knows how to effectively use AI tools like ChatGPT to get more done will replace you.
