I would try local banks, who hold their own paper for a year, before you give up entirely on a conventional solution.  

He shall not advertise for sale or lease any property in which he does not hold a current fee simple or leasehold interest

I placed my required ad in paper for 6weeks notifying the world about the opportunity to redeem.

That's a really simple calculation that doesn't take into account the time value of money or lost opportunity cost.

Your 40k return on paper just got cut in half really fast.  

Do I have any debt ...nope, nada, zilch...so the prospect of paying for a house outright was a simple matter of “yeah I don’t want any debt servicing” but I didn’t take in consideration the cost of self financing.

However, if you buy something with your paper, no need to discount.  

We did not have an A-paper product.

I'm pretty sure that is going to be the headline in the papers after the next housing crisis.  

Simple math why this should work is - I am putting zero dollars from my pocket and getting new roof and ALL financing cost is covered by electricity generated by solar panels...net-net, zero impact on my bottom line and with in 5 years the value of my investment is increased by almost $300K++ because of new roof and solar electricity!!
