having a real estate license is very important. When I do a search I check off, Available-Bank Owned-Estates. In my county that I look in there are typically over 160 properties as such always listed. I arrange them by dates and get to know each property. Even in my market one house lets say a 3-2 that is 1400sf can vary in price from 90-150,000 depending on location. So you have to know each community. I also look for price drops.
A house could be on the market for two months and get no action, the price is then dropped by $10,000 and now you have five offers.
But my point is I do this search every day. Most of the properties I bought were sold within one week of being listed. You have to be in the game and aware of what is coming on the market all the time. You snooze you loose . You really can't expect a hired realtor to do this for you unless you have a very special relationship with them. So that it cost be a couple hundred buck a year to be a realtor and have access to MLS is a bargain. I can also analyze the price almost instantly with the CRS tool. (Courthouse retrieval system) so if a home is significantly underpriced I know it and can act fast.
Acting fast is key because he who hesitates is lost!
