Barney (1991) talks about competitive advantage being achieved through having resources that are "valuable, rare, inimitable and non-substitutable'. It would appear you have such a resource. Given the competitor wish you to share how you do it, my guess is that it is not easy for them to imitate. This puts you in a strong bargaining position, until they understand the resource/product. So the negotiation stages they suggest are dangerous as in stage 1 you lose your edge before achieving a deal. Whether you go for a JV depends on how quickly you believe they could copy your current advantage, what access they have to markets you do not, and what extra resources they bring to scale the market offer quickly. If you go for a JV your strongest position to bargain is now, so do not reveal any key information until you have a good contract and an NDA.
Of course, I cannot fully know your situation, so this is just some ideas that might help and cannot substitute for professional advice.

A traditional business plan tends to have a longer time frame and be more focused on the competitive position. They appear to be asking for a sort of hybrid between a business plan and shorter term operational plan. Given your sector - property and construction - I would imagine they want you to demonstrate systemtic thinking with a commercial orientation. That is, they want you to layout specfic steps you would take in your first three months, and that these steps are sequenced in a sensible way. You might start, for example, with a research/investigation phase, an option generation phase and an implementation phase. Frameworks like a Gannt chart or PERT chart are well accepted in this sector and would be good to use. They demonstrate a logical systems approach. They cannot expect you to know all the answers yet, so concentrarion on a logical process with tasks broken down is the best approach, but do include some early stage suggestions so they can see your commercial flare.
I hope this helps.
