Rentometer.com hit the crap because they're requiring you have membership to make more than 10 rent rates...It used to be a free platform and now they converted to a subscription that I'm not willing to pay- anybody know any other sites that portray somewhat accuracy such as rentometer?

Spotcrime can give you email updates at weekly or daily frequency I believe.Id also add, but I have not verified accuracy of the following:http://data.baltimoresun.com/news/police/homicides...Although I haven't analyzed the accuracy of Baltimoresun.com Baltimroe city homicide map with Livebaltimore.com map, which I believe is done in junction with the city of Baltimore, it loads well and has the info in straightforward manner. http://data.baltimoresun.com/crime/baltimore-count...  

was not berating you ,,, you asked what questions to ask.. those are the questions I ask.. as 95% of wholesalers you will run into ( and you will find this out for yourself) are new  have never done a deal.. have no clue as to what they are doing and are not capable of answering your 12 questions with any accuracy  they just want to pimp deals and be done..   

It will also outlined the effort required to evict (remove) a tenant if it becomes necessary.In addition to validating the accuracy of your analysis, you should compare the return to that available to you through other vehicles of investment (stocks, bonds, etc) to determine if the added workload and risk associated with being a landlord is sufficiently rewarded.

So many variables most of which you just can not predict with accuracy.

I've found the accuracy to be very good for not paying a dime. 

With 75% accuracy means I have a demand of 200-250 units.

But, if you're analyzing lots of deals, 9% of ARV is probably going to be a lot quicker to compute than 10% of total costs (as adding up total buying, holding and selling costs typically takes a bit more time).Sorry to be pedantic, but the engineer/mathematician likes both accuracy and precision...  :-)

With that kind of basis of knowledge and networking, the material that you read here or elsewhere is more easily analyzed for accuracy.  

My criteria you ask: cost (Monthly or per lead) and accuracy of phone numbers mainly.
