Buying tru a Bank Trust is the safest way to invest, many Mexican citizens also prefer to use a Fideicomiso because no one can seize their property, The Government  can seize your property only by Eminent Domain, same as the US and other countries, and if you pass the property is transfered to your beneficiaries without having to present a Will. 

I have several bank accounts currently for different purposes but they are all tied together so I can transfer from one to another.

Unless the eviction can be transferred.

Maybe if I give some real numbers it’ll help.The building I leased for $107k, and will own at the end of the term.I currently owe around $65k.I want to use the equity in the building as the down payment and transfer the title into ABC, LLC.I want to rent the building to XYZ, LLC (which is the current business in the building and has been for 5 years, and is a real business) for $2600/month.

What if I contribute to my HSA with my current employer, then leave the job in 5 years, but leave the money in the HSA account, or transfer it to Ameritrade and buy a REIT stock with it and leave it in the stock until I am 65.

Doing proper due diligence will definitely help find some issues that may have been unforeseen, but I don't think there is a way to uncover every little thing and do a full transfer of knowledge from the seller to the buyer (especially if it's been with the seller for a while).

Transferring loads is not as simple as adding a header.

My title company said that title insurance would not be affected by the quit claim deed transfer to my single-member LLC (and this is who I used to complete this transaction - no charge).  

Venmo is another mobile optIon but they have a maximum transfer to your bank account.

As if we are still in the magnet tape world when it comes to data transfers.
