I would throw in a few more out there for you like Listing optimization: Rankbreeze and Intellihost, Data Companies: AirDNA, Mashvisor, etc., and guest verification platforms like Superhog or Chekin.

We have never had a tenant that was able to produce any factual data that supports their concerns. 

We recommend multiple tools to our clients depending upon what they needCRM > Followup Boss Data Tool > Batchleads | 8020REI | DataFlikData Management > REISift | BatchleadsSkiptracing > DirectskipSMS Marketing > Smarter ContactRVM > Smarter ContactCold Calling > ReadymodeDirect Mail > YellowletterhqIn my 5 years of experience in lead gen.. i have seen people getting success only by staying consistent on marketing. 

My worry is that while I am clear on the risks (extended timeline to get a tenant in, and expensive buildout) that I am not being nearly conservative enough - do I risk this thing sitting empty for a year, or years, and finally renting well below my implied rate? 

I make sure to be there when the appraiser is visiting the home and print out data on appreciation rates and comps and give him/her a personal opinion on where we believe the home should be appraised at.

When you finally get them on the ropes, they pack up and move out never to be seen again.

Thanks @Abel Curiel for the data on multifamily properties and markets.

I just got my first renters and I am finally in full tilt!

I finally took the plunge and have become a real estate professional.
