As far as gambling goes, I'd like to put myself in position to benefit from continually increasing rents, and not put myself on the other side of the table.

So was also looking for another solution like buying a list but not sure how accurate that info is and if it's worth it or already to late at that point. 

Nobody here is going to be able to give you an accurate answer...

Even if you could, it's a big gamble.

Also, I find Zillow to be much more accurate and one of the best online social sites to get some correct facts and specs.

This seems to be more accurate and typically increases the count.The criteria I search for most often looks like this:AbsenteeOwner OccupiedNo Corp/ Trust1-3 bedrooms30%-100% Equity4 yrs ownership (Last Sales Date)Median Price (for your area)SFRThis has shown great results and pretty high motivation.

skip tracing is what PI's use.. there is an accurant product and a bunch of free on line stuff no big mystery..

Be as accurate as possible with your CMA.  

I'm going to use fake, arbitrary numbers here that are NOT accurate, but they will allow you to get an idea of how powerful KPIs are when you track them religiously.Response rate: 5%Appointment rate: 25% (when someone responds, you book an appointment to see their home)Offer made rate: 50% (when you show up to someone's home, you actually make an offer)Property under contract rate: 25% (Your offer is accepted)Deals closed rate: 75% (Your active contract is sold either to yourself to flip or to another investor)Using this structure, we can find out what to expect for every campaign we put together:2,000 mailers -> 5% response rate: 2,000 x 0.05 = 100 phone calls100 phone calls -> 25% appointment rate: 100 x 0.25 = 25 appointments25 appointments -> 50% offer made rate: 25 x 0.5 = 12.5 offers12.5 offers -> 25% contract rate: 12.5 x 0.25 = 3.125 contracts3.125 contracts -> 75% deal close rate: 3.125 x 0.75 = 2.34 dealsSo to sum it all up, every 2,000 mailers you send, you can expect to close a little more than 2 deals.  

So getting to an accurate quoting is a key that we both want to accomplish.Anthony - thanks for the suggestion.
