I personally try to automate as much as possible and rely on great/trusted handymen, cleaners, etc. on the ground that can take care of anything that comes up and let me know about the state of the property.

Thank you,Phil Don’t have any experience with the mentioned mentors, but I do have 45 years experience in commercial real estate investing.Flipping (wholesaling) commercial properties require the same base of knowledge (real estate principles, real estate law and real estate finance) that is a foundational requirement for flipping residential properties; PLUS, extensive knowledge of the commercial property TYPE one is trying to engage with, and extensive knowledge of the local real estate market for the subject property type. 

We have a decent amount of cash to be able to invest so I'm trying to figure out what kinds of investment strategies local RE experts in Spain are doing.

I see some listings trying to do that, but they're pretty recently listed so it's unclear at how successful they'll be.All that said, I'd run your numbers at $1,200/mo and if that works for you and your goals, great.

You must be licensed in the state you want to buy/sell.

If I stick with my numbers and I'm trying to buy a duplex that rents for $3000 in today's 7.25% interest scenario, I'd have to not exceed $154,000 of debt at that interest rate in order to hit my numbers.

If one of you does not have an FHA loan, what is it you are trying to accomplish?

However, Amendment 1 introduces a new layer of complexity by trying property tax increases to the inflation rate.

If you are going to sell then you must understand the tax implications. 

A lot of real estate contracts include due diligence periods for exactly this reason.If there are no contingencies, you could still try negotiating with the seller.
