I'm in this strange position of being out of state and unfortunatley not having the time to visit or gain personal expertise.

Each brokerage has their own website that hosts listings.  3.

@Michelle Fenn  We had properties listed for sale, posted on local MLS, propagated to Realtor and maybe 100 other websites including zillow, trulia etc. 

There are a plethora of websites where homes can be listed - not just the ones dedicated to home sales, too.4.

@Sushil IyerWith my experience, to analyze properties effectively, you can start with resources like MLS listings, Crexi/Loopnet, tax assessor websites, or paid tools like Costar and Reonomy.

@Liam Alvarez  I've never seen an app or a website that analyzes all markets and spits out the top 3 you should invest in for the highest returns. 

Does anyone have some really good websites for accurate up to date data for vacancy rates, median rents, average household income, etc? 

I know nothing about the above firm you mention, but a quick look on their website shows they are likely offering you DSCR, so just general things to look out for in that world. 

Lexington is good if it's over 275K they go much easier on you but I personally do the surrounding areas such as the Red River Gorge which has over 600million visitors a year and no issues with STR

No app or website or discount brokerage or whatever can replace the value that a good, experienced agent brings to the table for the average consumer home buyer.
