Hence I’m still keeping DSTs as a future option.

I have non qualified stock options through my W2 employer now that has potential in about 5-8 years to exercise.

Is airbnb a good option here?

Evaluate your budget, savings, and potential financing options.

Perhaps if you happen to be married, consider options for your partner to become REP. 

All the options listed are GREAT!

I have a connection with a wholesaler/investor that has a property under contract there with the option for sub-to and I'm trying to figure out if that's a solid area to invest.

I'm weighing my options.

A good option might be single family properties in Saginaw - they pay their own utilities and maintain their own lawns/snow removal, so it saves you time and money, and they're easier to sell if the need arises.  

If your budget is tight, the best option may be for you to supervise the work yourself and hire qualified tradesmen directly.
