You’re in control of your corn. 
You’ll never be in full control of your land. 

For me I will get that land when 10% of my stack can afford it. And by that time I hope it’s safe to borrow against. 

My logic behind this is if I need to flee because of any myriad of reasons, I still have the corn to go. 

No one  can really advise you on the best decision for yourself. But it is a good mental workshop to think. 

A way  I think of it is;
The best time to plant a tree was 20 years ago. The next best time is today. 

Do you have goals and plans with this land that will suffer if you don’t act now?

I struggle with your same conundrum as well my friend. 

All our goals and dreams are different.
