@Maria Luna: I also live here in Metro Detroit. I don't know the area as well as some of the other folks but I'm afraid I'd have to agree with them. All of my properties I own are in Indianapolis. Great market, low taxes, and very landlord and real estate investment friendly city. I would STRONGLY encourage you to move there rather than Detroit.
Michigan is a great place to live and Detroit is on the up-swing. As others have mentioned - investing in Detroit will probably be the biggest challenge of your life. There is nothing that will be easy or glamorous.
Here is my advice to you to try and be "positive" about this move since you are "all-in."
Network, network, network. Attend every single REI meetup, local mastermind, and renegade you can. Give what knowledge you do have out for free. Help others as much as you can. Build a strong network of like-minded individuals whom you trust and rely on.
I'd like to be one of the first people on that list. I have a small network of my own I'd be happy to share. Just send me a PM. August is a great time to arrive in Detroit. If there is anything I can do please call!
Paul
