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.

for certain data like price per square foot I've found you can tell them to reference websites holding the data.So far ChatGPT seems pretty good for this purpose but I'm curious to see how Elon's superAI pans out.

Hey BP, Im curious on what some of you would say as the better route to go and why.I'm at a crossroads between:Starting and focusing on New construction for single-family houses to eventually get into being able to build small to medium editions as a long-term goal.

I check the SEC, FINRA, ratings websites for inside information on the principals in the company.

BP's website has a plethora of resources for people just starting out on their investment journey.

Just my .02I went to the PropStream website and checked out the features.

If your roofer didn’t provide info on this, I’d ask them or check GAF’s website.
