There doesn't appear to be much new information on the subject that is accurate. 

My issue is with the ones who don't do any research beforehand to ask a better question.A new person asking about house hacking a multi vs. a mother-daughter is a great question, and they have narrowed their scope and are doing the work.A new person asking how to get into investing is just being lazy and hoping for a Doug Flutie hail mary to land in their lap.I think of it as, how do you want to show up and appear to other people, in any forum?

I went through your other posts here on biggerpockets, it appears that you have tax related questions throughout the year such as selling a primary residence that you lived in less than 2 years.You may want to see if you are eligible to claim partial exemption.When selecting an accountant, make sure you select someone who will be able to answer your questions.

Today I received the notice to appear for their filings.

Turn Key can mean a lot of things to different people, I've seen "turn-key" with what appears to be the original, 50's era kitchen and bath.

In your case properties appear to be fairly low value already, which suggests low demand and the potential to damage property values by building mfh there.

Not sure what you win by telling them no they can't test except the appearance that you are hiding a meth contaminated house. 

That's how you get the best of both worlds.I will defer to your judgement / answers as you are going to be more of an expert in the area and I am just basing it on spending a few months there and potentially wanting to live there in the future.Maybe I chose a wrong word when I said 'poor'.I stayed in Madrid during my time and I just based my response based on discussions I had with locals and 'high level research' on the internetIt appears that unemployment rate is high in Spain at around 11 percent with a higher rate for those who are younger.A had discussions with many where they are mentioning to go outside of Spain if they want to further their career or get a higher salary.locals have told me that it is difficult to start a business in Spain from getting approval and the taxes are higher for those that are self-employed.My personal assessment, which I think agrees with yours, it will be hard to make a rental work if you target it to locals but if you target it to outsiders, you can make it work.During my stay in Madrid - I stayed in Chamberi, Lavapies, La Latina, Malasana and spend around $60 to $120 a night mostly in airbnb's(basic rooms with basic furniture). 

Aside from hanging your hat (license) with a brokerage, all you need is a laptop ($300 at Walmart), cell phone w/ hotspot, $100 per mo, some business cards (not required), a CRM (the one in your phone works fine when coupled with a task list - both free usually), maybe a web site domain @ $12 from Google, and a simple one-page site as a sales sheet.

This is a huge red flag to me, expecially as it appears the seller is also the property manager.
