We also install motion sensor lights on the side yard in case they need to access it at night. 

The subtle differences between terms like “remove,” “replace,” and “installation of new” can indeed lead to unexpected outcomes.I use a detailed excel spreadsheet to clarify expectations I'd have no problem sharing I use with all my clients that I perform work for.

If it’s too expensive to separate out the heating costs with the furnace see if you can shut off the second unit and install a separate heating system.

Additionally, installing a makeup air system along with a ducted vent hood seems impractical and costly.I've considered alternative options such as a recirculating vent hood, but I'm concerned about its effectiveness in removing grease and smoke. 

I have an employee that bought a 40X15 (600 sq ft) prefab metal building for 11,000 then spent 7,000 turning it into a home, for the 7k he was able to super insulate it , create a single bedroom, a full bathroom with laundry, and a small kitchen.

When I sold the building within less than a week the new owners were out there installing a post box and had complained about it enough to the post master that he agreed to let them have one.

The best way to prepare for this is to install a combo lock box on the property and provide the Appraiser the code when he calls.9.

I'm wondering if I should install cameras on the property as a security measure. 

Steps I was thinking of following:1) Get electrical up to code since its all 2 prong outlets and the panel is way outdated.2) painting of the whole house3) Demo kitchen and bathroom4) Renovate kitchen/bathroom5) install new floors6) input new appliances7) input new light fixtures8) etc.

What you are describing is similar to telling the power ball winner not to take his 50 million lump sum, and spread it out in installments so he can get more.
