Additionally, since we are out of state (Washington) and unable to do walkthroughs of prospective properties, Chris has been great about taking videos for us, which has been very helpful. 

Continuously educate yourself through books, podcasts, and videos, such as BiggerPockets Podcast and YouTube channels.

Get informed about real estate investing by watching videos.

It even comes with training videos

Despite paying a substantial fee, I found that beyond basic instructional videos and repetitive weekly calls, there was little substance to aid my learning.

As you learn go to meet ups, try to network/glean from experienced people and listen to podcasts/videos. 

We also can't have renters dealing with the humidifiers as it is a mold problem/foundation issue if it isn't taken care of.We are taking pictures and videos of everything, we have multiple professionals that have documented everything (and told us to lawyer up) and have neighbors that we have already had agree to discuss their  drainage problems when we get a lawyer.

Video tours of the properties help this.

Contrast that with our $500 leasing fee which is only paid to us after we've done the marketing, video tour, showings, found tenants and actually rented the property.
