Here are a few considerations to help you decide between a 4-plex and a duplex:Cash Flow and Returns: A 4-plex typically generates more rental income compared to a duplex, potentially offering better cash flow and returns.

Since I already have an interested buyer I would like to FSBO. 

Another option that can potentially be free is looking for a mentor who is doing what you aspire to do in real estate and see how you can be of value to them so you can learn while helping their business.

EDUCATE YOURSELF - yes, it will take time, but will lead to a selection that better meets your expectations & avoids potentially costly surprises!

I only heard about Partner Driven last year and so far so good 👍🏼 As a licensed REALTOR and loan officer, I knew the traditional buyer pool was going to shrink due to the looming interest rate hikes.

I would love to receive advice from people about what to look for and not when crunching the numbers on a potential property.

My strategy would be to protect the money optimally from the government and from other potential filters and to optimize my time to do what I enjoy doing instead of worrying about real estate ventures. 

Consider what questions the potential mentor may ask and how you would answer.

“Let the buyer beware” was the underlying viewpoint of the day.  

I'm no expert on the tax point of view for US buyers in Spain, but I would be more than pleased to point you in the right direction with regard to property investment in Spain.
