It looks to have a very high number of mobile homes for sale.

You technically CAN break it up on Schedule E; however, it is not the best thing to do for audit purposes or an actual breakdown.You should have an operating/partnership agreement together and you should have a dedicated bank account for the property.  

I own a mobile home that I rent out and I am looking to make my first MFH purchase this upcoming year to house hack. 

On propertyfinder.ae (non-mobile version) in the price graphs for areas like JLT, Marina from May 2021 I see price/sqft appreciating from 12 to 14%.

Are there tenants looking for mobile homes to rent, and what are the going rates?

The buyer had the mobile home demolished. 

Today he drove over an hour into the woods for us to look at a mobile so my husband does not have to commute.

You can get around that issue if you have a dedicated home office space that is used for the operation of your rental business. 

They not only specialize in self-directed IRAs and solo 401(k)s but also have an entire team specifically dedicated to supporting BiggerPockets members like you.

It sounds like you’ve got a great opportunity with these two mobile home parks, especially with the flexibility that seller financing provides.Out of curiosity, what terms did you negotiate for the seller financing?
