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. 

Then after the sale I saw them marketing these deals heavily to potential investors on their websites, making it look like a huge win for them, when that definitely was not reality IMO.

@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. 

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. 

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

Hello Vivian, there are a lot of opportunities to invest in Tulum downtown, the beaches are occupied only by hotels and restaurants, this is the best time to invest in a pre construction unit at lower price than the finished units with a difference of 25 to 30% bellow market price, check this website to view some opportunities www.tulumrealty.net

The problem was completely operator error on my part and website design on theirs.
