From my experience, I recommend preparing a solid foundation to show potential investors you're serious.

You don't need to know everything to get started; you need a foundation to build on and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

Once you have this team in place, you should have the foundation to invest in any market confidently while not being there physically. 

if it's a manufactured home on a permanent foundation then it may not be an issue

Your major concerns are still the same (HVAC, roof, foundation). 

The property also needs Foundation drip zone installation.

One of the properties had foundation issues; I was aware of this from the inspection report but it ended up being quite extensive.

My experience is that mobiles/manufactured homes fall into three categories, a. still on wheels treated as a vehicle and are are on rented spaces b. wheels removed, the unit is put on a foundation and skirted, on rented space c. wheels removed, the unit is put on a foundation and skirted on owned land and treated as permanent, which qualifies for a mortgage.

It explains the team that you should develop to have a strong foundation under you while investing remotely.https://www.biggerpockets.com/blog/core-four-real-estate-team
