The Online marketplace could be the key to your success.Need out of your lease in as little as 48 hours?

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.

As for laws, well those vary just about everywhere you go, though at least Madrid is working on cohesive federal regulation for short-term rentals (whereas that will never happen in the States), but I completely agree with your point on the good deals in high-crime ghettos angle - the concept of "ghetto" as it is in the States just does NOT exist in Spain, and personally I find that a much easier thing to work with in terms of identifying path-of-progress opportunities.Our company offers a few different things, but right now we're working on rebuilding our property management division on the Costa del Sol, targeting purely vacation and short-term rentals (we sold this division last year when we got a tempting offer and knew that pending regulation was going to greatly shift the marketplace).

FB market place is second to none.

You can have it take still pictures every X seconds, and some of them can take a picture when they detect motion. 

You are not the tenant's friend, counselor, priest, sounding board, shoulder to cry on, private detective, police officer or anything of that nature.

Well you may have to deal with this Harboring -- Subsection 1324(a)(1)(A)(iii) makes it an offense for any person who -- knowing or in reckless disregard of the fact that an alien has come to, entered, or remains in the United States in violation of law, conceals harbors, or shields from detection, or attempts to conceal, harbor, or shield from detection, such alien in any place, including any building or any means of transportation.Encouraging/Inducing -- Subsection 1324(a)(1)(A)(iv) makes it an offense for any person who -- encourages or induces an alien to come to, enter, or reside in the United States, knowing or in reckless disregard of the fact that such coming to, entry, or residence is or will be in violation of law.Conspiracy/Aiding or Abetting -- Subsection 1324(a)(1)(A)(v) expressly makes it an offense to engage in a conspiracy to commit or aid or abet the commission of the foregoing offenses.Ask yourself of you want to take the risk 

Now you may be wondering how we ended up with Engelo as a guest - and it's an interesting story and shows that you can't let 'distance' or other obstacles stand in the way of opportunity.It started because Engelo advertised in the BP Marketplace for someone to join his Ohio Cashflow team.

While there may be other surrounding rentals that are just at $1200 without/with maintenance.You still must be competitively priced in your market place.  

If you do self hosted, typically you will go to either the free repo (http://wordpress.org/themes/)  or to a commercial marketplace (http://themeforest.net/category/wordpress or https://creativemarket.com/themes/wordpress) and pick a visual layout you like.
