Include the finish selections as well so they understand what is being installed (Carpet is cheaper than hardwood and if you install hardwood herringbone thats even more expensive).Then you have the general terms as part of the contract which are insurance requiremens, licensing, schedule, indemnifications, lien waivers, case of default. 

One more thing I should address:  Installing cameras inside of a residence with other tenants can be a HUGE legal violation.  

I just wrote an offer for full asking price at 30 day close, with a contingency to extent at BUYERS choice for 30 more days if I don't get an favorable response on the electricity install costs.

Installing thermostats with regulated heat control (we pay heat) 3.

We installed fresh flooring throughout, updated the bathroom, and gave the entire property a fresh coat of paint inside and out.

Also I would talk with those that install systems they usually have a good feel for areas and maybe will do an onsite inspection.for me if just vacant land and all i need to do is dig a 3 foot hole to get soil samples I am going to just do that.
