@Toan Le I use a mobile app called Tellus.

And a site dedicated to real estate investing and not small business ownership isn't the best place to ask them. 

I am native to Spokane WA, where I have built a mobile welding and fabrication business, which I have used to fund my real estate business.

I used to keep dedicated handyman but everyone eventually becomes unreliable.

I don't agree that a person with mobile property should not use one of these.

Purchase price: $39,900 Sale price: $39,900 Two Mobile homes for sale at 39.9k Great Investment opportunity located in Woodville Florida and Havana Florida.

I can't get the picture in view in mobile, but if you have soil "erosion" under a patio slab you're likely looking at soil transport instead (soil getting moved by water).

Financials are in the link for the Calculator below, property is made up of a five unit building with all all separate utilities, a four unit building with separate electric but landlord pays for oil (2 year old boiler) and a mobile home that tenant pays all utilities.

Is anyone scooping up properties to make rentals, or finding land to put mobile homes/storage facilities? 

Assuming the county zoning will allow a mobile home park, is it cost-prohibitive to start from scratch and build a park on 5 acres on a good highway outside of town?
