Just know that it's a longer time horizon.

Think about this example: depending on your age, time horizon and investment ability you could grow your $50,000 contributions into $500,000 or more, and all of those gains could be tax-free!!

Additionally, many of them are individually parceled and are now owned by various owners, so building any efficiency in these properties is challenging unless your investment horizon is over decades and you can buy up each one as the owner is ready to sell.

We're getting a lot of attention from out of state investors with deep pockets and long time horizons.

You also need to live in that house a little bit longer than your 18 month  horizon (24 months), but at that point due to moving to another area of the state or country-reset your opportunity to get an FHA.  

West Edge (formerly the Horizon Project) is the expanded medical research complex that I think Scott is referring to:http://www.westedgecharleston.com/The vision for this was in place 10 years ago but the economic downturn put the brakes on it as it did so many things. 

I moved to Self Directed IRA Services aka Horizon Bank.  

There are some things best left to the pros and this is so far past that line, it's a dot in the horizon.

Without going into much detail, time horizon can also greatly skew IRR one way or another.

@Jonathan Frith  I like the idea if you have extra capital to spare and a long horizon.
