Smaller has higher occupancy, less rate fluctuation; bigger has a lot more rate fluctuation AND occupancy fluctuation, but you make bank in the high season and in the 4+BR space your ROI is typically better than the smaller ones that are more consistent.  

In the meantime I can make the garage into a duplex or live/work space to rent on the back of the lot I retain? 

The properties that I rent would be fully furnished and then listed on short term rental sites such as AirBnb, HomeAway, VRBO, etc. as available spaces for travellers using these platforms.

I would recommend learning as much as you can about the real estate space and see where you can best fit in based on your strengths and current situation.

There is a crawl space where all utilities are separate (gas/electric/furnaces/water heaters).

Granted, I've been actively engaged in the commercial real estate industry for 17 years so I know and understand this space well, so for me it's likely easier than for other investors new to all real estate types.That said, there is a reason that many of the investors who've been interviewed on BP, written books, and grown a portfolio often scale or "trade up into commercial" over time, so they can achieve the benefits I mentioned above.

Yes, this may be a big NO-NO for most of you, but we are considering to relocate there in the future to have more space.

It had sat on the market for a while but I saw a significant potential in the space and extras that were already present.

Now I’m back in the space of getting rocking again.

There is a total of 30 spaces for mobilehomes.
