The sellers have not been responsive when asked to provide that information, which is why I was wondering if it's a typical practice prior to submitting an offer. 

Anyone have practical experience with this that we can discuss further?

If you put any information on social media you are practicing real estate without a license.

It can also be probably fight in court if this is a monopolistic practice if you think about it but who will want to fight it :D.  

From talking to locals, there's a couple of issues than need to be addressed, some are the non-ecological practices that some of those developers have, unfortunately, our government profits from this investors and allows them to destroy manglers (which are the natural water purifying system of that area) dismantling hectares of mangroves and degraded the habitat of resident and migratory species burying animals alive.There's proof of fecal material floating beneath the city of Tulum, only 20% of the water is sent to the water treatment plant, there's no infrastructure for the exponential growth.The landfills in the middle of the jungle that is leaking hazardous pollutants into the freshwater system and that something that developers won't tell you.I love my country and it would be a disaster for everybody if this place ends up like some other great beaches around the world, that are completely ruined by greedy investors not following the rules.There's no urban or comprehensive master plan, and one of the risks is that Tulum will be like Playa del Carmen is today, overgrown and with environmental devastation.I will advise doing a lot of research before getting something in Tulum, different country, different rules, and practices.

They were realistic about the outcomes, so we went the practical route.

Quote from @Mike Arias: Quote from @Chizitem Ibeneme: I'm a college student, and I plan to start investing in multifamily homes once I graduate, and I recently started looking at deals on Zillow just so i can practice underwriting.

The resources we had:- a bank (conventional) that lends money up to 35k for 650 credit score- hard money lender with APR 120%- seller/community (who acts like he doesn't want to talk at all)- a real estate mentor that costs $35K to useThe "answer" to this exercise was:Use personal credit to borrow from the bank and spend the $35k on mentor, and then mentor has the "connection" with the community bank to negotiate a deal and brought a 70K property for 40K with FMV of $140K.

I feel like having some good experts helping me clearly identify best practices and targets for success (instead of guessing) to be extremely helpful.
