Not a lawyer but 12% is usury in CA, unless you're licensed. 

My partner contributed his land, and found his own 'silent' capital partners - so the attorneys had to negotiate some defensive clauses to ensure each of our 'sides' were protected.Since he is contributing the land, but you are contributing actual capital, consider having your lawyer negotiate a clause where you both are 50/50 voting partners (and both guarantors to the loan), but you get all the income distribution (minus what your partner requires for annual taxes) until your capital is repaid; you can even specify who gets what percentage of the tax depreciation credit. 

My lawyer is researching the ordinance and I know there have been several threats of litigation to block it, but I haven't heard anything concrete as of yet.

If you can do your business by email and phone, I can connect you to a couple of good RE lawyers  

Thank you Time to higher your own lawyer for this.  

I am about to contact a lawyer but I am confused, do they have however long they please to pay this amount?

Any worry about being chucked out of the country due to immigration crack downs?

And sic your lawyer on him.

All of my colleagues and mentors recommend lawyers.
