You all need to go after motivated sellers, not just off-market sellers.FSBO are all about offmarket, but most of the time FSBO want market value.So to answer your question, and to be more helpful and of value than you think...here is what you need to do.Distinguish off market sellers, from motivated off market sellers, because this distinction in your marketing efforts will make ALL the difference when it comes to  results.Then reverse engineer your strategy based on the behavior and distinction of those motivated off market sellers.So if you understand what I am saying here... your question about "templates" is wrong.It is not about where do you find templates for off-market deals... your question should be, where do you find  motivated seller off market deals... because when you know where they are.. you don't need no stinking templates.You just need to explain how the process works and the result...well:If I had a mic, I would drop it right about now.Good luck my handsome feller!

As far as sourcing the lot, dealing with zoning or the city on new construction permits, engineering plans, etc. 

@Brett JurgensSolar on my house would be around $40k and my electric bill is not even 200.

I'm not sure if the OP is talking just about water, heat, electric etc.

Here are some items that are specific to warehouse:Loading DocksInterior FinishesHVAC SystemsSafety and Security AlarmsLand ImprovementsSpecialized Electrical SystemsMaterial Handling EquipmentAs you can see, cost segregation can allow multiple items to be reclassified to shorter useful lives, accelerating depreciation and creating immediate tax savings.

While you can try and do a DIY cost seg, it is very tricky to understand the tax law piece and the engineering/construction piece.

We're bringing a knowledgeable general contractor to the property walk-through next week to assess potential risks, and I will also check the HVAC and electrical systems myself, as I have some experience in these areas.

The appraiser isn't an engineer and I wouldn't trust their measurements.

Right now Im at the engineering phase and subdividing phase.

Of course, I'm out the deductible (2k).Incredibly, one week later, another 6ft diameter oak fell across the neighbor's front yard (this time, it damaged HIS house) and took down the power lines to my rental property which ended up causing just under $2000 of electrical work and tree removal expenses for me.
