For double bore I either put a dummy plate over the unused bore or, as someone else mentioned, put a non-locking knob on one of them.I'm a huge fan of the Kwikset Smartlocks on individual unit doors but I prefer the Schlage keypad locks on common doors.

Take a look at the Solds in the blocks around the subject property. 

I am now considering partnering up with two other individuals(1/3 each) to invest in multi-family homes.

That being said here’s my 2 cents on your individual expenses.  

AND as long as individual power and water meters.  99.9% chance this is all illegal and only one power meter and one water meter which makes it difficult to rent to 3 different tenants. 

If you are going to start partnerships, I recommend going with individual LLCs.

The cost to move the trailers plus the risk to them that the tenants would want to move to the new location mean that it is not likely the block owner would do anything. 

I know my understanding of investing has been greatly expanded through getting to know the individuals mentioned above.

We haven't made any concrete decisions about where we want to establish a team out of state but Memphis, Oklahoma City and Kansas City have stood out as early front runners.We're excited to learn, excited to be here, excited to meet other like-minded individuals, excited to build relationships and most importantly, excited to keep taking action to start reaching our goal of breaking my 'golden handcuffs' and reaching financial freedom!

It is a small (real small) duplex in Mission Beach, ~1 block from the ocean.
