It is definitely a long term play/gamble but after 40 years of doing this and surviving three recessions you learn a couple of things along the way.

You're asking if you should gamble on appreciation.

#1 can just be a savings account- don’t do something silly like a brokerage, that is gambling and you can lose the money#2 I self manage my units and have a few I manage for friends.

I have refinanced properties in the past, but with this being the first time I've done so with a MHP, I want to have as much info as possible before making a decision and 'gambling' $3,700.Thanks for any information.

Investors were buying with monthly losses gambling on future appreciation.

That's a gamble in any market, but it's a very poor one in today's market.I would see what your payment would look like if you refinance it.

Leave the gambling to the habitual losers.

You are essentially gambling that growth in your primary market will spread to the secondary market you invest in. 

I quit cigarettes, I quit gambling, I started making coffee at home, and eventually I became responsible with money.

You're really betting on appreciation, which is a real gamble right now with ridiculously high prices and a good chance inflation is going to worsen.
