@Jason GriffinRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

New investors tend to stress out for years about their first deal or two, and then when it comes to the most important peice of the puzzle regarding how their property will perform and how passive their experience will be, they get lazy and don't develop a process for screening. 

Might as well start looking for the word of mouth referrals for those now since you are going to build an empire.  

Very low income people tend to have hardly any disposable income If it were mine I would be very hesitant to do this.  

I was hoping to get suggestions and/or contractor referral in the Fitchburg area on how to address the issue.

My guess is it'll have to mainly be word of mouth referrals from other investors.

I'm not too much of fan of yellow letters.. some of the examples that I've seen tend to look a little unprofessional.

And those properties don’t tend to appreciate.

Isn’t the advantage of MHP ownership the fact that you own the land (pad sites), have limited maintenance and limited management, and that tenants tend to be long term because mobile homes are costly to move? 

I have a few referrals in the Columbus that I would be more than happy to send over.
