So, debating "do I need a CPA" or, in your case, "do I need a Realtor" is kind of pointless.As a person who has spent an expansive number of hours in a law library, pouring over chapter upon chapter of various laws and statutes, as well far more hours than the average bear also pouring over tax codes.... 

Same goes for number of LLCs and what to fund them with, since bear in mind that CA tends to be more cumbersome and expensive to have LLCs than other states. 

So I guess the most important questions would be, are you planning on renting it out to an RV owner short or long term?

Bear in mind that you may not always have the data necessary to know the true cap rate of a sale.

We had management in the region anyways so this wasn't as difficult of a decision to bear.

As you mentioned: it will be hard but not impossible to find the right deal-- something you should bear in mind also is that when you are looking for 2-4 units with FHA, duplexes have to pass less "tests" to qualify your financing and are typically easier to get into.

For example, 4th of July week, Bear week and Carnival I got $4,000/week for.

An orchard or a vineyard is a systematic planting of fruit and nut-bearing trees or grapevines as opposed to individual plantings for ornamental purposes.

He did an inspection when I took out a load bearing wall and ran some new outlets and lighting circuits,  didn't have any issue with me doing all that myself.  

My only question would be are you open to implementing the BRRR method with this duplex or are you looking for something move-in ready?
