In other words, all the other MTR hosts are dealing with the same expense.To control this expense, I always recommend an utility cap where tenants are charged for any usage over an established dollar amount.  

Careful going outside state lines -- contract for deed is not allowed in Texas.I didn't think COD is illegal in Texas, just perhaps not recommended anymore, because it is difficult to comply with the rules or regulations. 

I'll take any and all advice any of you have, but the two things I'm looking for specifically are: what sites, services, and/or software you use and recommend for sceening and managing tenants? 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I can definitely provide a recommendation.

Anyone you recommend in Minnesota?

I'm a little biased (am the owner) but seriously pumped to see you recommending it.

Florida is a unique state for MHP law and the insurance has gotten very expensive there too.I recommend checking out @Frank Rolfe's mobile home university content if you haven't already.

While outsourcing overseas may be tempting, I would recommend nailing down your processes prior to teaching someone, or you'll wind up with their processes, at best. 

@Serge Hounkponou Recommend you first figure out the property Class you want to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?
