When I buy it the spread must be wide enough I can sustain even what a bad market can throw at me in the form of vacancies or ect.

Because of my situation I won't be quitting my job until I'm stable enough with enough cashflow to sustain and grow.

The park may not be able to sustain itself in the long run.Also, while the mobile home is a depreciating assets, the sheer savings on the costs of the home compared to stick built housing is the balance that makes up for it.  

This approach resonates with a lot of investors who want to stay as liquid as possible.  

The trinity study back in 1998 is the primary study that ran all the statistical analyses over different time horizons in the market and discovered that withdrawing 4% per year would give you a >95% chance of having sustained income for a 30 year retirement without running out of funds. 

@Gary Parente, It seems to me that your goal is to achieve $120k in predictable, sustainable income each year so that you can retire......yes?!  

If you don’t know the basics, knowing a “program tool” will not be a sustainable way to success.  

Your 3 points really resonated with me with what people like John Maxwell, Brian Tracy and Bob Proctor often speak on. 

I think that for me, personally, I have the goal of attaining early financial freedom aggressively, but also like to maintain a conservative financial position with lots of liquidity and a hefty positive margin between my income and expenses.If I had a huge lump sum of money that I came into all at once (and was otherwise unlikely to be capable of rebuilding said sum in less than 5 years), I'd be looking to invest it consistently, according to a system that I could sustain.

@Senad Pali It's all relative...my personal opinion is that this technique is not sustainable...and you're killing your cash flow and equity by pulling it to roll into another property.
