Those work well and you can also get them that work off a cell phone provider; I used to have one that was US Cellular enabled. 

He told me he owned a few mobile home parks in town (they were large and had high lot fees) and this is what sparked my curiosity.

Would the buyers/borrowers be purchasing with the intent of putting a mobile home on the property and making it their primary residence?

@Stephen Karathomas The values of mobile homes and what you can pay for them depend on the area(s) you're working in.

Now I'm wholesaling mobile homes on land and in parks. 

They are not very mobile and this neighborhood looks about the same, demographically, as it did at the time of the Race Riot of 1967 where buildings all around your property were burned to the ground.

We’ve found a great option for us in Tennessee with a cabin (currently used as a str) and a mobile home.

Cameron is our local manager in Bend and I have his cell phone.

The last time I represented a mobile home park purchaser, county health department allowed four MHs per septic tank. 

Now that I am in position, I would like to place a mobile home to generate some passive income, but I don't want to use my savings for the down payment.
