DISCLAIMER: Just the ramblings of a dolt on the internet, for entertainment purposes only.

The internet will do it for you.

There are a few books on the internet but not very detailed.

The internet has 1000s of ads.

This kinda works with just internet shopping but is greatly magnified if you are actually touring houses.

However, an internet forum isn't the place for this advice.

It is really in the adjoining land owners best interest to grant easement for a reasonable cost or they may end up being forced to give it for nothing.In the future, call the city, county and state to ask about something like this rather than consulting random people on the internet, haha.

Unless this Seller is living under a rock and does not have access to the Internet and only use a fax machine to communicate with the outside world. 

Do some research on the internet for brokers local to you and decide if you want to go with a small boutique brokerage, a big national chain, or something in the middle.

They probably have Netflix or something and they mostly just care about a good internet connection.Also be sure to clearly state if you're offering a private or a shared bathroom.
