Writing a business paln

[Monty McLamb]

I am currently working on refinancing 3 of my properties to get cash out (60k to 80k) for buying/investing in new properties.  The loan officer is with my local branch and has always been very helpful and offered me the best rates.  I told him I am looking to scale my rental portfolio and turn this into a business.  He likes the idea but has asked for a business plan to support my goals.  He said it would go along way with the underwriters if I can show my experience and the cash flow my investments can create.  Problem is, I've never done one.  Is there anyone that offer advice on creating a business plan for a property investment company?  What numbers should I be sure to include and how best to  show my calculations and assumptions?  Thanks in advance.
