Haven't gotten too deep into the costs yet, but doing the preliminary analytics. 

@Christopher BrownI would agree with @Joshua Strickland, it depends on the market on how accurate the analytics are.

The more important thing is to trust your analytics.

Question - what are the best software packages that can calculate short term rental analytics? 

I'm an ambitious and analytical young investor focused on developing a portfolio of cash flowing SFH and small multi-family short term rental properties in North Florida. 

Looking forward to learn and use data analytics for better investing. 

If you want to look at an ARV from a future potential investment value from you renting it out, then you would need to find rental comps as well as investment sales comps to go with that rent to project a value off of NOI.It's going to be hard to pull comps without some sort of data source like Costar or Crexi or Real Capital Analytics.

This issue thought me big two things, one never inherit tenants and two even if you do not have the social security of the tenants you can report delinquent to the credit business bureau, I use Sperlonga Data & Analytics if you are interested.

I am not opposed to using a platform like Propstream that would provide hard analytical data on markets, demographics, and such, but even just in terms of news about developing markets and real estate news I don't really know where to look for specialized real estate news that is not subjective/someone's personal take on what is happening in a given market or something.

On the commercial side I used real capital analytics (RCA) which was super reliable....is there an equivalent on the resi side?
