Different investors have different strategies on buying properties and there's probably someone offering some sort of $1000 training course on each one. The idea is to get really good at one strategy and look for properties that fit your niche. As you get more comfortable, you'll learn new strategies and evolve your strategies to fit the properties that you are working with.
A lot of people use the 100-10-1 mentality for looking at properties. The idea is to analyze/look at 100 properties. Of those, choose 10 that you would like to do further analysis of and/or make offers on. Finally, of those 10, you'll probably end up buying one. Don't get frustrated or overwhelmed with this process. In real estate, you make your money when you BUY!!! You realize your return when you sell or rent it, but buying the right property is key!
In my next post, I'll discuss where to start looking for properties!
