I believe that once I close on that first (second, currently renting out prior primary residence) property I can begin the process of refining and replicating for maximum efficiency.

Also taking on your advice about electric, I want to have as effective an energy efficiency rating as possible.

The architect had two closets and a small but very efficient bathroom.

Weed out the dilapidated MHs (which from the outside is most of them) Sell off as many MHs as possible striving to be that no park owned homes kind of place to reduce the maintenance costsHire professional management which should ultimately make the park more efficient therefore creating more cash flowDress the place up with some landscaping, maybe a new sign at the entrance, an overhang for the mailbox area, maybe a play park to really make is a classy family community.... basically whatever will make it appealing but still cost effective instead of the junk yard it is nowThere are roughly 5-7 of the approximately 9 acres for sale that are undeveloped.

Anish,Investing 600K to get $100 cash flow doesn't sound to me like a good plan :)I think you can invest it much more efficient if you just look out of state.It will give you a much better price to rent ratio, plus in many states, laws are landlord friendly and not tenants friendly as in CA.If you want to learn more about out of state investments please feel free to check this meet up group:meetup.com/Los-Gatos-Real-Estate-Networking-Meetup/

Operating expenses are very low because I use gas dryers (instead of electric), tankless water heaters for hot water, and high efficiency, front load washers to save water.  

Check and proactively replace all of the toilet flappers and check flushing mechanism to make sure its flushing efficiently. the flapper(s) could have likely degraded and the bad seal might slowly leak into the bowl and cause a frequent refill of the tank. flappers usually need to be replaced every 5 years anyway since they degrade. toilets have always been a cause for high water usage in one of my condo buildings.

Highly energy efficient home.

ATLANT calls itself the "Worlds Real Estate Blockchain Platform" and the whitepaper discusses, in depth, the idea of tokenized real estate ownership and the use of blockchain technology to create more efficiency and ultimately lower costs of real estate transactions. 

However I'm not doing the maintenance side of the property management efficiently.
