The low hanging fruit is gone.

I was networking a great deal when I first started and it has been fruitful to say the least.

The problem with that is that it's easy to blow through your savings sending out all of these letters, and then give up before your efforts starts to bear any fruit.  

If (and most people don't) you do the math for the risk and factor in the cost you should be worth for taking the risk and the number of total number of house you invest including the time it takes to find a property and then factor in flips you don't make a profit on and those you actually lose on there are many more fruitful things you should be doing with your money.Example?

Its a question to get rid of fantasy land sellers and unmotivated sellers as fast as possible without ruining the fruit for a later call. 

This will help you narrow down and analyze properties.Some of these classes are for agents but are open to the public if they pay a fee for the course.

In fact its the low hanging ripe fruit that we are picking.

I just bought and sold one last week that was owner occupied.Think beyond the low-hanging fruit. :)
