As for the initial investment, I am working towards securing the necessary funds and am open to exploring various financing options that can facilitate this.Despite facing numerous challenges and setbacks on my real estate investing journey, I remain determined and resilient.

A friend of mine bought some houses from them that he thought were occupied and running smoothly because rent checks always came through on time.

I'm not super educated on the options.

As a rule, I could argue to have the IRA (Roth preferred) NOT hold property, but control is with options, leases, etc, so the profits come into the IRA.

An attorney friend of mine owned just such and park, and was impressed that she knew more about RV parks in Texas than any broker he spoke to.  

The oener finaning option.

To start your journey, I recommend focusing on building your network by joining meetups and engaging in online forums, while narrowing down your first investment based on your budget, market, and goals.

My friend is selling his house and is open to an assumable mortgage.

That $3,000 is typically the annual cost for a full service property management option. 

If you don't have free cash available that limits lots of options, but if you do, that is another story.
