The first being that I can direct that time and energy to my work and easily multiply whatever small profits I would gain from a small investment property.

The homes will simply be older, the land obviously the same size, however the revenue may have gone down by half if you decide to sell these properties and simply collect lot rent, which may cut your gross income in half.There is definitely a lot more to consider that I am not including in this quick comment, however in my opinion this park may not be the best use of your time, energy, and capital.. at it's current price.

Your energy is always best spent in the present and planning for the future.

You're on an investing forum so have you put much energy into the investment side of things?
