If you're not sure of you preferred direction with your next property I would invest in understanding investing more thoroughly and read 5-10 books as well as speak to other experienced investors.

So if I understand, you would get a loan the normal way and then the bank trust is an extra fee that comes along with owning the property in Mexico?

I could take look at it for you, and help you understand it if it's a standard lease, no need to pay me, although I am not a lawyer.  

I understand where you are coming from as we always did our taxes on turbo tax as well until we purchased rental properties. 

You don't need to know everything to get started; you need a foundation to build on, and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

It’s understandable.

Its my understanding through my reading/research that 35% is the typical number.

You will want to fully understand the tax reporting burden you will face. 

From my understanding, I need a Proof of Funds in order to get under contract.
