Land is valuable as I could purchase a new mobile home and install and less costs since utilities are already on the land. 

Reasoning for asking this is that it could potentially be a beneficial long play on acquiring a property through assumption, and as we go down in interest rates, utilize this monetary benefit to refi as it comes at a mere .5%.

Make sure utilities are available, and that you have tap fees included in your estimate, as well as engineering (site plan), architectural plan, and other bits you might need to consider for your market (landscaping and costs of sale, for example).

The important things to consider about HOA fees is that they usually include some utilities: Water/Sewer, Trash, sometimes shared amenities like gym, clubhouse, pool, and they are saving you the time and headache for property maintenance: lawn care, tree timing, roof, siding, etc.

Utilities, including common area will also be different.

Looking for thoughts and suggestions on how to utilize these new funds for real estate investing.

The income includes things like late fees, a rented garage, and utilities that are billed back to the tenant. 

As along as you take the lessons from this and utilize it on your next deals (yes, plural) you'll make great progress!

I am NET cash flowing just over 1k (includes maintenance, repairs, cap-ex, vacancies, utilities), which is pretty good considering this is in SoCal.
