@John N Gietzen the primary things you want to look at with list providers is 1) the variety of criteria available (equity, value, vacancy, owner occ, etc), 2) the timeliness and accuracy in YOUR AREA (this is why there is no point in asking anyone which is best unless they are also in your area), 3) what data is included in your list - just a name and address, or complete details on property, phone numbers, transaction history, equity, etc. 4) user interface - you are more likely to use a tool YOU like, and 5) price.

You could be around $2M hopefully less ($1.6M - $1.7M) depending on the accuracy of those repair estimates and expenses.

The more accuracy you get with the known items, the more room you have for imprecision on the lesser known items.  

IMHO, this is impossible to evaluate with any accuracy.
