Klyde,
When I got my first cash out refi from my home, I was lucky to have my residential mortgage banker who I had worked with for 10 years and who refinanced that loan, put me in touch with her buddy in commercial lending. She put a good word in for me then called me to say "don't screw up!"
So maternal. I still love her though.
What was nice about this besides the intro was I had two professionals in small institutions looking out for me. They were then and still are very helpful to go to with questions about what I want to do next. I always get their ear. The VP of the bank knows me by name even though I am a very small time customer there.
When I went to the bank for my commercial loans using my cash out refi from my home, I had along with all the usual financial stuff like Tax forms, P&L, a pro forma and a business plan. I worked on that plan for a couple of months.
It may sound a little like over preparing and maybe the bank even thought it was kind of "cute" but I learned A LOT writing my plan down and making it make sense. I had a couple of friends who were in business look it over for feedback and I learned SO MUCH doing this exercise. I encourage you to write up your plan for making money doing RE. You should do this no matter what kind of lender you are speaking with.
Good luck to you
Diane
