I remember seeing a post from Alan May about the 9 things he carries.

To that, I would add:

• hand sanitizer
• toilet paper
• lockboxes (one combo, one Supra)
• business cards
• Agency brochures
• water

I used to carry a mallot, spare signs, etc. in my car but, I have moved those to Ray's van since I bought a little two-seater! 

I have an entire large plastic box filled with goodies.  All kinds of things like tools, toilet paper, paper towels, spray bottle with cleaning solution, booties, flashlight, socks, walking shoes, etc. 

WD40, scissors, screwdriver, and a few other things. 

Bolt clippers are a favorite of mine.  It gets peoples attention. 

But basically a few tools like a hammer, screwdriver and set of pliers.  Kinda like a thumb in the dike, cause no further harm, just get the job done with a minimum of drama.  

i have changed light bulbs to prove the fixture worked and we did not need the consultation of a licensed electrician.  

I always carry an extra Buyer Packet and Seller Packet.  Also doggie treats and some "promotional items" that I can give away as I am doing my daily tasks.  And of course, a supply of water.

I have a truck which has no trunk!

I DID have a swing out wheelwell toolbox installed, and it has everything from compass to outlet tester to graphite spray to tools, 5 lb sledge, bailing wire, metal tape, metal zip ties (THE BOMB) jumper cables, nuts bolts screws washers, laser pointer, 100 foot measuring tape and I'm sure I am forgetting something!

My basic tools. a chair, walking stick, umbrella, paper towels, clean rags, and my basic tools. Then for Real Estate, binoculars for roof & chimney viewing, Riders, 3lb sledgehammer (for signs) etc. 

Towels, clean up after wet feet.

Rubber gloves....those darned dog walkers.

Spray cleaner...little Billie didn't realize the slider was closed.

Knock down wasp/hornet spray.

A variety of tools for signage, measuring, illuminating,fixing, barricading and testing.

I used to carry a large amount of tools, especially the items needed to install or remove signs Fred Griffin Tallahassee Real Estate .

Now, in the "not really" side of things: Remember those signs like the baby on board but they said ex-wife in trunk. How about a loaded shot gun for when my revolver just won't do?

Toilet Paper

As a city dweller, I got rid of the car when I moved here. Instead, I carry a backpack everywhere (like the typical resident here). Since we almost entirely sell apartments- we don't need to carry much. I do keep a few things readily accessible though. Typically I have extra buyers packets, business cards, booties (for no shoes in the apartment), tissues. Weather permitting and with clients- I often carry an extra umbrella or bottles of water since we often walk a lot.

I used to keep forms in my car, but I found that I never used them, haha.  Currently, I have a sign, a tape measure, but I do not have a flashlight since there is one on my phone.

Tools, nuts, bolts, nails, zip ties, stick on numbers, tape, staple gun.

Include some footware use when walking through wet grass or a wet basement.
