Security deposit witholding from Tenant for Damages (FLORIDA)

[Paul Johnson]

I have 5 students who's lease expired and they all moved out, upon inspection inside my rental home, I found damages, took photos of it. hired some contractors from thumbtack app and facebook locally to fix some major wall scuffing, repainting  and many more issues. 

I sent a certified letter within 15 calendar days notice of intention on the deposit with printed copy of estimates for the damages.  Tenant asking for photos and explanations on how I came to this conclusion, I will be sending photos , that is not an issue, but  am I required to give detailed explanation how I came to those estimates?
