I also occasionally have random people come to my house trying to intimidate me into paying them to do odd jobs. 

Just keep in mind the image it presents.

Let's say 10 years in, you get deployed to <insert random combat theater where you have no internet access and limited phone access at best> and you have 30 properties at this point spread across the country.

Finding one that fits my needs is not as easy as cold calling random firms in the area. 

How do I take the image in my head and turn it into reality?

The end result looks fantastic and if nothing else is worth the learning experience and the beautiful images you can use for marketing future deals. 

But for the one-off random tenant?
