Property in middle of future development

[Michaela G.]

So, 12 years ago I bought these 2 vacant lots . There had been whisperings of future developments for years, that hadn't come together. 

NOW, they're planning a 320 acre mixed-use development that's been announced and I have these 2 lots smack dab in the middle of everything. The city it's in owns most of the parcels and have been buying off others the past few years. I once offered them to buy mine for 100k and they laughed at me. 

Well, They're breaking ground this fall and are expected to create +1,000,000 sqf of space, retail, hotel, office, residential. 

What's the best way to go about maximizing my sales price. I'm no longer willing to sell for 100K now, as they took their time. 

@Jay Hinrichs , I believe you've dealt with property close to development. What advice can you give me? I know there'll be a time soon when they'll want (need) to buy those lots.  How do I set myself up ahead of time, so that I'm in a good spot when it happens?
