If you do decide to use a Listing Service, try them out on a trial basis.

These trials ultimately provided me with invaluable hands-on experience and inspired me to develop my own systems and methods for conducting business more effectively.

My company pays for DotLoop so I use that the most and my Realtor dues pay for Transaction Desk with Authentisign, which has a free 30-day trial.

As a new landlord, you'll certainly learn the business, likely trial by fire, as we did.

Acquire a profound comprehension of navigating economic downturns and unforeseen circumstances, and uncover efficient tactics for adjusting rental pricing to triumph over the trials of a volatile market.

Trial by fire for sure! 

Do they offer trial periods?

There's going to be some trial and error involved.
