As a property manager, creating a standard that establishes the trifecta of benefits and tension is good. 

You can't compete against the all-inclusives unless you offer complimentary food and booze or you're cheap, as you seem to be confirming.This being said:1) Properties in Mexico/Cancun trade in USD so you have no foreign exchange risk in Mexico while properties in Colombia are traded in COP, the Colombian peso, which has been tanking over the years, eliminating any hope for capital gains for American investors.2) You can get a mortgage in Mexico but you can't in Colombia so even with lower revenue, Cancun would likely still be more profitable, even if you don't take capital gains into account.3) The political risk is much higher in Colombia, especially at this present time.Is Cartagena a bad investment?

Maybe they benefit and that's great, but a large part of valuing wealth and what it afford comes in the struggle to obtain it.

That was the biggest benefit that came up time and again was the amount of time that they stay in the property reducing turnover.

It's a great opportunity to be here and one thing that brought me to this community is the idea that we will not swindle grandma but we want everyone to benefit from our deal.

I cannot think of a way that you (the LL who stands to "benefit" by them repairing their own space that they are paying you to use) will come across in a positive way.Plus, the tenant who incurred damage due to the other tenant's leak, may have some legal rights to have the tenant with the leaking pipes pay for the repair in both spaces.Now, beyond the legal side, you also need cognizant that most mom and pop tenants (which I assume these are) are not great with their money.  

Please note, I did not include the tax benefits from deprecation.

Great post it gives insight to how you worked the systems and benefited.

It takes a lot of work to find a tenant, your commision gained from the income should only be for the services rendered while the tenant is in the home ( in my opinion ).Some additional fees I can think off, are maintenances fees, for larger projects that require a lot of management and research.

Even though you feel you don't reach the full cash flow potential, you gain on making the lives of those families more comfortable.
