Circular references and whether order of calculations is key for correct result

[Spitfire147]

Hi All
Attached is a simple residual real estate appraisal I have built.
It includes circular references, which I know are not ideal, but I have 'Iterative calculations' ticked under options.
This appears to now be working, but I have had to really play around with the order in which calculations are made to make it work. Previously, and I cannot work out why my cell L75 was equaling my Gross Development Value in cell L25.
Could it be that unless calculations are undertaken in the correct order that the boxes in yellow will be incorrect?
I would really appreciate peoples comments on this and whether they think this appraisal now 'works' and is correct.
Many thanks.
Alex
