I am in my 40s and have a long way to go before I can actually retire from my high stress job (although I dream of it every day).

When I have a vacancy I am not as stressed because I am not making a mortgage payment.

There is a ton of competition, but with preparation, you can jump on the offer before others do.I strongly believe networking is key is real estate (I do sales for a living and absolutely can't stress enough how important building contact lists are).

It is hard to ask other people what is and is not a good deal when you are not clear what your end goal is.I fell victim to this and now when I help fellow investors I really stress that having the right mindset is the most important thing.
