I had a fairly complicated model I was doing and same thing they approved me to quickly just send in 5k to go to the next level..

,I agree with a lot of what @Larry T. said and think you need to really evaluate your model and numbers. 

Interesting investment model and I agree the headline is just a bit overarching.

CU's who have low deposit rates, usually also have low commercial lending rates.But at the end of the day, you just have to call each of these banks and see if they lend to your business model.

It could also be that the specific FICO models that we use as mortgage lenders are more conservative than the credit card FICO models - which would make sense.

I have seen models that show the two metro areas converging in time, not unreasonable to envision.

Should I start learning how to write up business models to find investors for much larger projects like cardone suggests?

If Ford was still only producing the Model T, it would have been left behind nearly a century ago. 

2 year escrow, 1 year re-model, doors open and business is good.

But...just because the model works for him, doesn't mean it is what you should be compelled to do it.
