The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

If there is demand and the market supports a market for mobile homes, it could be an opportunity.

To get access to Eric’s team you’ll be have to pay extra for a program called do-it-with you or do-it-for-you.

Maybe to have extra cash for repairs. 

With all of that said, my main goal is to have long term appreciation and if there is a little extra cashflow at the end of the month, great. 

Unless you are planning on investing in your back yard and have extra time to spend, getting a good PM is very important.  

You either have to earn extra money via sweat equity (working as your own PM or do the renovation work), or you have to be ok with a negative cash flow.  

What data supports your claim?

You can use client data to support your work as an investor-friendly agent without making it a pitch.

If they have nowhere to go or don't know how to find a next place, and no relatives who are helping them, you will be the only person that goes the extra step to help (even with advice) which means you will get the sale at a better price and help someone.
