Why don't you plan on buying a certified plane.  Go ahead and lease a space for your certified plane while you look for one that meets your needs.  In the mean time, you can "occasionally" park your experimental plane in the spot that you rent (for your certified plane).  If it takes you a few years (decades) to find the certified plane so be it.

Another option is to let a friend let you tie down in his spot on the occasions when you are in town and he and his certified plane are not in town.   If it turns out that you are in town far more than he is, so be it.

Lastly, if the airport is really going to close in 2 years, all this is a short term problem anyway.  You will need to find a more permanent solution to the problem in the not too distant future.

Good luck.
