The certificate is $125 and can be later used as proof (when applying for permits, or when selling) that there are 3 dwelling units. 

Or if its an 80% mortgage contingency, have them give you proof of funds for the 20% they will have to put up.

I didn't steal it, my subs didn't steal it as far as I know, and with no proof there is no reason for me to give in and replace it.

I like the "must have picture as proof thing".

You might also be able to add the interest to the basis of the property if you incurred the expense in process of buying the property(after you identified the property and your draw was necessary to show proof of fund to close the deal).

I'm a big believer in 'proof of concept' before expanding. 

I've heard it enough times that I'm hesitant to buy your story without proof.

When I say or claim something it is ALWAYS followed by proof to justify my outrageous claims.I am not saying that youtube is crap.

Purchase contracts on the MLS typically use standard contracts which will likely require you to have proof of financing or funds.

In most areas the burden of proof is on the state not the individual.
