Let's compare investing in a market you don't understand to a person in a room being instructed to throw a dart at a target, but the lights are turned off, they are spun 10 times and they are told to throw the dart and hit the board.

The manufacturer puts a clock in the unit to go off rendering it useless. 

Yeah they hadn't even given me wiring instructions and now they have gone dark.

I have a system to get it rented and if there’s a maintenance call my handyman has specific instructions and the tenants always are home when someone comes over.  

I filed the matter at the court and followed the instructed protocol.

. - Indoor sprinkler plans with hydraulic calculations and manufacturer spec data sheets.

We don’t want to subdivide and build yet but to put a manufacture home on it to generate some rental income for the next 10 years or so.

Bigger Pockets is normally for real estate investors....so if it's something not real estate related (like a manufacturing business for example) you might not get very good answers here.  

If you want to stick with the current one, at least have the tenants sign a one-page letter that introduces you as the new owner and provides instructions for payments, reporting maintenance, etc.When it comes time to increase the rent, I recommend doing it once without hesitation or apology.

We also provide a toilet plunger, hair removal tool for the shower/tub, and instructions on how to reset a garbage disposal, etc.
