contributing vacant lot to Roth IRA?

[Michaela G.]

I wonder how I could move a vacant triple lot I own into a Roth IRA. I believe the maximum contribution is $ 5500.00 .

How is the value determined?

I initially paid $ 2500 for it, in 2005. Is that what the value would be based on?

Tax assessment right now is $ 8800. 

Present market value about 150K. 

It is part of an assemblage that I've put together in the past years and I expect a developer to buy everything in the next 4-5 years. I think it would be really great, if I could then put most of the purchase price on the lot and lesser amount on the adjoining parcels ;-). 

So, if I could move this lot into a Roth IRA, it would be beneficial for me.
