I could potentially purchase one mobile home all cash, but renting out mobile homes is very difficult: high vacancies, low rent, and high HOA costs for utilities. 

It was a groundbreaking study because it was the first to study returns of stock, bonds and residential real-estate since the 1870's across multiple countries. https://www.frbsf.org/wp-content/uploads/wp2017-25.pdfIn the whole period...real-estate had the highest return with stocks a very close second (about 1 percent behind) and bonds lowest.In the modern era, it was essentially the same but with stocks in first place and real estate a very close second (about 1% behind) and bonds lowest.And even in the modern era there were many decade long periods where real estate did better than stocks.Also, there is no way to know what will happen in the future and it's possible that stocks could perform lower for a longer period( or real estate).So, to me it's a no-brainer that I want the diversification of having *both* in my portfolio (and would never limit myself to just one of the other).

I am newer to mobile home park investing and I just put one under contract because I was thinking about purchasing it but the more I do research, it seems like a bad idea.

Heck yeah good mobile home deal!

It's not just data; it's knowledge, empowerment and opportunity rolled into one groundbreaking solution.However SMFLs aspirations go beyond this.

Another thing to consider when making a website is most traffic these days is all mobile traffic so make sure your site is mobile optimized.

The property has a laundromat ($24K/yr), mechanic shop ($7200/yr), and 2 mobile homes (owned by the tenants) on a month to month lease ($400/mo).

It wasn't a mobile home but the lesson still applies. 

So for me its:- Private lending - Syndications - but MF or commercial - I do not have background on underwriting a mobile home park, or self storage etc. thus I tend to stay away from those types of deals.

I plan to flip my first property this year whether it be a mobile home, single family home or land.
