@Chris Rich Good point.

Even when I hear stories about investors that scale quickly, take on max leverage, partner up, etc. and get 28 doors in 2 years, it's either a situation where all details and context are not communicated (rich parents - for example) or it was a "just because something worked does not mean that it was a good idea" situation.You win the investing and real estate game by never being a forced buyer or forced seller and letting the compounding effect of time take over.

. - 6% cap rate reflects a nice safe part of Los Angeles, California, a prudent investment, not one that will make anyone rich overnight, but a place that higher net worth individuals park wealth to preserve it (imagine the depreciation write-off). 6% cap rate also tells us, right off the bat, that we're going to be in the ballpark of 60% LTV.- We will stipulate that this is hypothetical. 

Need to be well located and be amenity rich - I assume this to be true in quite a few markets.

A wise investor will not try to get rich quick with shortcuts.

If they're inside of the range above, you're overpaying by a lot and the GC, is getting rich off of you.

Here are a few I recommend: "Rich Dad, Poor Dad" by Roberto Kiyosaki; "Set for Life" by Scott Trench; "The Unofficial Guide to Real Estate Investing" by Spencer; "The BiggerPockets Ultimate Beginners Guide" found here on BP; "The Book on Rental Property Investing" by Brandon Tuner.

The big differences are that RV parks are typically amenity rich which requires more overhead, can be seasonal in nature (but not always), require a nearby destination to work well (as opposed to employers), and use values that are typically 2 points higher in cap rate.

The perception of you as a rich STR owner verses a resident is probably an important one to address.I think some of the problem here is that you aren't a member of town. 

The rich get richer, and the poor get poorer, and not a single worthwhile word of any authority was ever said in my home and or my school about how someone who is broke might stop being broke, and why that could be a worthwhile life goal.
