FSBO - Seller requires Purchase Proposal before giving any info

[Joseph Parker]

This may be a dumb newbie question but I haven't run into this before.

A local commercial property is listed for sale by owner. I reached out asking for more information and willingness to sign a non-disclosure if necessary. The seller stated to me the asking price and requirement of me to submit a Purchase Proposal so he/she can have an idea of economics before sending me any current lease information.

Just curious to know what exactly the seller is asking me to include in this Purchase Proposal...?
