There are no laws, rules or regulations preventing any foreigner, American or otherwise, to buy property in CDMX or Mexico for that matter.If, by having success, you mean getting a profitable investment, I'm sure many American and other investors got that over the last few years (I personally haven't since I've focused my efforts on Mexico's beach markets, which are far better in my opinion.

it is not under a normal use when the appliances break down.it comes from neglect, especially when they are new.I have already made a decision.If I get a pushback they can rent a crappy place, not my place..there are always options...Appliances are provided for a convenience and not a part of rent.Tenants will be responsible and I do not have to suck anything up.Now I think we all know why you wanted to prevent your tenants from talking about you.

Some say it’s possible to implement this strategy in Germany, while others claim you can't, due to regulations preventing the sale of mortgaged property before 10 years.There's a lot of confusion and misinformation, and no one seems to have solid information.This strategy is well-documented in the USA, with numerous videos on YouTube.

How can you prevent them from DIY?

What prevents someone which this type of experience creating a Youtube channel or writing a book to share their wealth of knowledge?  

I am getting a really sneaky suspicion that they are stealing money and finding ways to charge unnecessary fees and want honest feedback from anyone who has recently dealt with them.

I think screening will be your best friend if you go this route to prevent the most headaches. 2) I'd say the biggest problem renting by room is potentially laws about unrelated persons living in same household.

It's possible that this increase can prevent a lot of people from buying and might even force others to sell.Do not wait for your taxes to increase.

This will allow me to have better deals and can profit on the work as a contractor.Are their any clause which prevent this?

Thank you for sharing your story here to help prevent other new investors from falling into the same trap.
