I'm working on sifting through tax information now.

Remember: the most important thing for most investors is sifting through potential deals and finding the next good one they can pull the trigger on.People always think that wholesaling is the best way to start.

If you go on E bay you can buy pretty much any name brand guru's written material or tapes that those that pay the big bucks get and then when they never use it they sell it on E bay for 50 to 100 bucks.. its worth buying as many of those as you can from all different guru's then sift through it all and take what you like and implement those strategies.Bottom line the way wholesaling is taught in most course simply is not legal anyway at lesat without a RE license.

I am looking to buy 2-4 unit investment and got a list of about 150 properties.My question is how would I go about crunching the numbers and sifting through all of it, it because I obviously didn't  get any info from the sellers as far as taxes, rent and stuff like that so how can I narrow things down and figure out what to pick as my first property?

Why are you guys sifting through Short Sales...

The common theme here in BP is ... all the info you need is here for free, which it is.For some people who works 40 + hours per week and wants to get out of that  9-5 asap, they may not want to take the time to sift through all threads, pod casts and such, these courses may be a more time efficient way plus from what I seen they off money back Guarantees.
