Hey @Monique Booker I am a wholesaler from St Catharines, Canada and I was in your shoes a few months ago. So I'll lend you my two cents.
1. I do not know the NYC Market so I cannot tell you if it is a good place to start or not. I found that starting in a county that has lower value homes that are surrounded by counties of higher value homes is a good place to start. I found people in areas like this are more experienced with investors and open to the ideas
2. Real estate is a HUGE area of study. I would pick one county so you can learn that county's market as you learn the in's and out's of real estate. For me learning the basics and eventually, the advanced stuff in real estate was made a lot easier by staying in one area where I could apply all the new skills I was learning.
3. In Canada, we have really strict anti-spam laws so I do not have access to that many lists. To avoid being overwhelmed I would start with two different methods of finding houses and base the lists and methods you use to find these houses off of your buyer lists. For example, I look for 2 types of properties; teardowns and turnkey properties. I target these because I have lots of interested buyers for these types of properties. No matter how many amazing deals I have they mean nothing if I don't have a buyer to pick them up.
Buyer specifies what they are looking for -> What lists are those properties usually on? -> Study and learn those lists -> repeat once comfortable
4. Analyzing deals properly, in my opinion, is the most important skill for wholesaling, tied with marketing. If you cannot analyze what is a good deal and what is a bad deal you'll look like a chump when you send it over to your buyers. If you want tips on how to analyze and appraise different types of properties let me know and I can help!
