I've been doing this mental exercise for a while hoping to get some thoughts on this.Thank you all.

I'm not sure but I assumed you received documents from PennDOT stating that they intend to exercise such power.

What I’m hoping from this exercise is to learn what’s it going to take from a cost/time perspective.

(Or, rinse and repeat the first exercise, but maybe with a Lot that is NOT generating income yet)?

We exercised our right to cancel the contract.

Those items like kayak, paddle board, BBQ grill, lawn furniture, floor mounted pull up exercise bar, stationary bike...stuff like that which the tenants are free to take advantage of but it is not part of what the rent includes.I think hotels do that when they say they have "complimentary newspaper service, complimentary WIFI". 

What I regret is not exercising the pro-tenant laws Massachusetts has in place, holding the landlord and property management liable of the commission fee they charged me since they did not do a proper inspection of the unit between tenants.

Then, when it comes time to exercise your option to purchase, you'll be more favorable to the lender.

You get the peace of mind that if something happens to your cash flow, you can exercise the advantage that you have just bought yourself and be able to to skip a payment or two.  

Usually the consideration is the payment of money but it need not be; it can be anything of value including the promise not to do something, or to refrain from exercising some right.The payment does not need to be a fair payment.
