I've found most hard money lenders to be pretty lax when it comes to business plans.
Typically, my clients have used a pretty simple word document with the following info:
Executive Summary with address and pertinent property info like type of property, age, condition, general income and expense info, net operating income, info about owner/borrower, maybe some info about their general financial status, credit, etc.
Always good to include color pictures and a few maps, like regional, city, and street level.
Current Rent Roll and expense statement are very helpful, as are historical statements going back as far as you can to show them the property is stabilized.
Appraisals within the last 6 months are helpful, but they'll rarely rely on them. If it needs rehab, a quote from a contractor or architect would be helpful.
Feel free to contact me for templates of loan requests used by my clients.
Good luck,
