Writing a proposal and timeline for purchase of building

[Javan Bowsher]

I am new to Commercial investing, but I had an idea recently to turn an older movie theater that had gone out of business into a rock climbing gym. I have approached the owner of the building and she would be interested in selling, but would like me to send a proposal over. Is that similar/the same as submitting an offer in residential real estate? And is the timeline for commercial sales different, as compared to residential?

I have hired a consultant to help with a market analysis on whether the market can support a climbing gym, and I am waiting for those results before I submit any offer to the seller. Should I also wait for that analysis before I approach investors about potentially investing with me on this deal?

Sorry for my ignorance, I’ve spent a fair amount of time educating myself on residential real estate, and not so much on commercial, but this idea really excites me, and I’d like to try and see if it could work!
Thanks!
