Pre-Foreclosure Resources

[Nghi Le]

Newbie investor here.  What's the best website/resource to find properties that have an auction date within a month away?  I'm currently using foreclosures.com (not foreclosure.com), but wondering if there was something better out there.

Is it a good strategy to go door knocking on these properties that are close to being auctioned off? Do you think it's a more effective strategy than contacting the homeowners when the NOD is sent out? Is a 1-month time-frame the sweet spot, or something longer/shorter?

Thank you in advance!
