The hard part is that finding private money when you are new in real estate is like unicorn hunting and if you don't already have that relationship it will likely be hard to make happen in the timeframe you need.

But I am looking forward to finding that gem and start building out my portfolio.

We build triplexes in columbus OH and contract with a lot of out of state parties.

Is there a way to get a construction loan with the original property still on the land so I can do a new build on part of the property and then slowly rehab the historic property?

Regardless of what market you select, you would be wise to put some resources into building your off-market deal funnel.

I'm also building an ADU here at my primary residence that we'll operate as a STR.Of my Detroit doors, 3 are Section 8 and one is operated as a STR.

Depending on your relationship with the person and the trust level you could always offer to let the project manager put cash into future deals to increase their percent of the profit.

Also wondering if I can get a second loan (Commerical) looking to go bigger with a 5+ unit building using the 75% of profit from first one. 

It should be a long term relationship and not one property and done.

I have just started brokering relationships between my massive buyers list and lenders like yourself.
