I did not want to simply rely on one source so I figured there are people here that would be up-to-date if such a manner was so as well. 

Would greatly appreciate advise on how to start sourcing the land and/or connect me to land brokers who can help.Thank you in advance!

When trying to analyse STR I try to use as many data sources as possible, AirDNA, Rabbu, Pricelabs and good old networking, ask around see what other investors are getting for their units. 

The data @Devin Conley posted is pretty solid from my experience (I do not know Devin nor how he sourced the data, just going by my own investing experience).  

For most, this isn't a realistic option so they update some of the most important regions themselves and copy the data from other providers where they don't have coverage.This is a big problem with these big consumer-grade real estate analytics platforms—you don't really know the source of that data, its frequency, etc.

Wholesaling real estate is a great way to start as you must become familiar with deal underwriting and deal sourcing. 

Sometimes it's not the tenant's fault - tree roots, collapsed pipe, old materials from a previous tenant, etc.

HUD.GOV is originating source for FHA loan info.

Using criteria like price-to-rent ratio, pop growth, employment trends, and wage growth, relying on multiple sources (PropStream, Zillow, Rentometer, FRED) to calculate averages. 

Quote from @Sri Reddy: I am a newbie to real estate investing and looking for guidance from the teams here to understand the sources from where we can find any small retail spaces to buy.
