If I am self managing my portfolio, what do I need to check/confirm, and what easily available tools are at my disposal (online, other) to help me do this? 

Purchase price: $940,000 Cash invested: $250,000 I purchased a Self-Storage Facility.

Has anyone in this group had success with self storage syndications?

I am completely self taught intentionally.

Are there specific tools, presentations, or approaches that help them feel more confident in taking that first step?

Most Hard Money lenders may also require you to have the investment property under contract, in order for them to feel confident you won't try to sue them and you can pay them off either by selling or refinancing  the property you are using the cash out proceeds for.

Apartment buildings, assisted living facilities, self storage, restaurants... 

It has been my life's mission to build my own duplex, house hack it & use it to catalyze the BRRR cycle.As I get closer to breaking ground on the project, I'm still not 100% confident in it's feasibility due to the costs of land & construction considering it is mandatory to secure an appraisal 20% above build & land cost. 

Then you can self-manage and learn all about tenants, contractors, etc. 

I currently self manage so I don't have systems/team.
