This way I'm measuring cash flow against total invested. 

No matter what you do, it's critical to play the role of editor and ensure the content is accurate and still in line with the tone and overall style you're aiming for in general.

We will need to test and measure this for at-least a quarter to see the results.

So my aim, is to translate this advice, into something a little more tailored to my situation.So my question is this...if you were just starting out, but you had a large amount of capital available to you, how would you change/adjust your day 1 business plan/strategy to maximize your results?

I measured the distance between pins and it only measures 94 feet, not 100 feet.

Is there a target average daily rental rate that we should be aiming for to make a selling price like $550k work?

Since we are just starting out and will just be approaching less-experienced friends and family for investment, we want to make sure we choose the structure that best suits the situation.We're aiming for a contract that is pretty much them lending us money without being able to get involved in our ground-level operations.

Our aim is to find a more affordable way to assess our investments prior to purchase.Thank you
