When I sell my business I will have 300k to invest puss 300-400k left over after I buy my residential house.

I’m also open to partnerships or collaborations if this aligns with anyone’s interests or expertise.

A mentor can be a great idea but make sure they have walked the walk and align with your goals.

After the job is completed and punch list is done and client approves then a check for the remaining 80% can be given for final payment.In my experience I've learned that if you give someone too much, or make it to easy for them, then, they have nothing left to strive for.

It's a matrix where you'll want to find something that is on the spectrum that is in alignment with your risk tolerance and understanding. 

There are significant details that I'm choosing to leave out regarding rent payments and balance left for the owner as you terminated the lease early. 

However, we’ve faced challenges with lead quality: Most leads are solo traveling nurses, and their budgets don’t align with our 3-bedroom property.

As for myself, I tend to rely on the left side of my brain.

That strength i carry that lets me stand alone is beneficial but also as I left that crowd i was never able for unknown reasons to reconnect to a better class of people or even network.

Paid off my primary when it got down to 90K.... not a ton of loan left, so I just paid it off, but still had plenty of $$ to invest in other things...it didnt tap me dry to do it.Exactly.
