The problem here is that the 2% rule is simplistic. It makes assumptions about what operating expenses will be that are, more often than not, inaccurate.
You need to learn Capitalization rates if you are going to get a little more sophisticated. 2% ROI per month would work out to be a 24% cap rate if there were no expenses-- but some operating expenses are inevitable. The problem is, of course that those operating expenses can run up to 50% of the gross income which brings your cap rate down to 12% which is good, but not great. If the properties are truly without operating expenses (again, unlikely) a 24% cap rate is fantastic.
Cap rate= Annual NOI/purchase price. 10% is good, higher is better. If you are not finding properties in this range you are either not looking hard enough (don't do bad deals just because you cannot find good ones) or you are in an over-heated market where fix-and-flips might work but buy and rent probably will not. That said, in the most over-heated market there are good rental deals out there but you may need to reconfigure the property in some way.
That said I just bought a 2/1 condo with a 42% cap rate. Even after I split with my investor partner he will get 21% ROI (no debt) and I will make $4,200 per year. All in all not too bad. Beautiful apt. in good neighborhood. REO not long on market.
Lots of those deals out there in my area.
Oh, by the way, one last thing. Whenever the newbie says "there is absolutely no way to get a deal that . . . . " it is not true. While I am encouraging you to get a little more sophisticated in your analysis I would bet that there are 2%/month ROI deals out there in your market. They are not going to be easy to find. And when you do find one you may need to move quickly. But just because you looked at 50 and didn't find one doesn't mean they are not there. The good news is as you do this more they somehow become easier to find, mostly because you learn how to reject the duds more quickly.
