If you haven't put the best possible,  experienced people around you, I might suggest getting involved with your local real estate investment groups...many of these people will have experience and contacts that could help walk you through the steps required to make this project safe and profitable or to show you why it might be something to walk away from. 

Would love to hop on a call once I start narrowing my search down and to hear about your experience so far in Columbus.

Its going to be managed by a property manager and thus a passive investment which is allowed per h1b rules.However, I am being needed to procure state and county hotel tax certificates which almost seems like I am launching a hotel business in the records of state.I am starting to wonder if this can cause issues down the lane when renewing my visa or applying for green card.If anyone else has a similar experience or own STRs on h1b, urgently want to discuss this with you.

That said, no direct experience with mobile homes.

I am hoping to leverage % of profits for their experience.
