Order a valuation before renovation?

I'm going to embark on my first ever renovation project to draw out equity to fund my next purchase. I planned to open up the kitchen to a newly fenced up sideyard.



Is my project milestone below advisable?

1. Order a valuation (previous valuation was only 8 months ago, during settlement)


2. Get quotation for fence; start fencing


3. Get quotation for installing French door


4. Buy right sized French door


5. Fence complete; start removing window and installing French door


6. Repaint wall with French door


7. Order a valuation; and depreciation schedule


8. Refinance $$$
