@Brett Johnston To be honest with you, I use to do a lot of construction and flipping homes in the past and then I stopped because of the market.
Now that I am in New York, NY, I am getting back into it , but I am doing it slowly as I set up a real estate and property management company.
Its like I am getting everything ready before I start , in a few months. Believe me you don't want to set things up after the headaches begin. I don't want to make the same mistakes I made before, so I am going to do it right this time, from the lesson I have learned in the pass.
I believe the right way of doing it, is to learn from others (as from a Mentor), either through doing your own research (Books and CD's) learning from the accomplishment or failures of others. This comes from history and others experience.
Secondly, set up a budget(s) and a plan or goal to where you want to go, and everyday work on the goal(s) when you have the time.
Third, set up connection through Bigger Pockets and else where such as a local REIA in your area. Talking with them, you will find out what your market should be and they might even help you fund your next project.
As for your questions: small family resident in major NY,NY is far and fair between, most of the families have the property all bought up unless you have a lot of money to invest in the beginning. Where I live, there is just multifamily dwelling available. However, the farther away you get from the major city, there are great opportunities available to look at.
Do your self a favor, stay small and local until you can really get a handle on what you are getting into. There is a lot of investor con-games out there. I like to be able to get into properties that I have control over even if it is run by a management company. (hiring / firing) I don't prefer to drive 200 miles to solve a problem that can only take 5 - 15 minutes to fix.
Best wishes for you and what ever you decide.
