If there is 30K in here when the partner wants to leave,  their share is 10K. iii) Value of future cash flow-This is the prong that I am seeking advice/guidance about.

@David CohenWelcome to BP, and congratulations on making the decision to invest in your future via real estate.I have written a few blog posts that may help you get started here on BP, and with your investing.

The option consideration is just what it says: the opportunity to purchase the property for a price in the future, but not the obligation.

Your losses are locked up and pushed into the future.

I think I am going to stick with regular deadbolts for now and drill them out in the future if I must

But knowing the cost of having my equity stuck limits my growth with future opportunities.  

Asking for future discussion sake...Thank you for helping me, help others.Regards

What strategy/tactic changes will be needed to thrive in the future?
