Maybe purchase and no renovations (that are unnecessary) until units are vacant.

Here's what I found...BatchSkipTracing.com...PROS... provided 4-8 numbers per property... included "Preferred Mailing Address" columns which gave an alternate mailing address for the owner (which could be useful for mailing campaigns)... each number was given a "Phone Score" of 0-100 (which presumably is a measure of the accuracy or their confidence in the number provided.)... provided email addressesCONS... did not note which numbers were/are part of litigator lists (which I hear can be costly if you call someone on this list)REISkip.com...PROS... provides email addresses... gives up to 3 numbers/property (less can be better)... provides info on which numbers are part of a litigator list... provides property data (info gathered from public records/census data)CONS... some of the data seems unnecessary With that said, it's difficult to say which is "most accurate".
