Net proceeds - Is the amount of cash that goes into your exchange account.

I recommend reviewing your local laws to understand the requirements involved.

Also helping was a relationship with that bank (deposit accounts) and good credit. 

2) Accountant - Has anyone found a decent accountant with knowledge of REI here in Portugal?

From day one I treated my involvement in real estate as a real business.This means, I had an advertising budget, a lead generating and follow up process, a back end process and money source and above all an experienced mentor.  

In this manual (which I assume could be modified to provide to tenants) I include all the financing information (which you would not include for tenants) bank accounts, mortgage accounts, payment information, and mortgage payoff), a list of the contractors, what each contractor does, a list of upcoming planned or necessary repairs, and a copy of all leases associated with the property.

How much upfront costs are typically involved in a project before you know if it's a viable project to pursue?

But they auto-deposited $50 into my "marketing account."
