You can drive through neighborhoods and look for these in person.Start a direct mail campaign to let the owners know that you're looking for properties that meet the following criteria (list criteria that matches their property.)

This property came in through our direct mail campaign and it took a bunch of hand holding from @Mark Redmann to get this deal done.

Before you know it you will be able to up your monthly budget.I like to look at the monthly budget as an average since I like to switch up my marketing pieces each time for my direct mail campaign.

(Great for follow ups)Direct mail tends to work best when you send a campaign: 5-7 different pieces, 3-5 weeks apart from each other.

I plan to hire an ad campaign manager to drive leads to my site as well, but out of the box how effective is L.P.?

Most peoples direct mail campaigns arent successful because they give up on them too quickly, marketing for properties isn't quick, easy or cheap (despite what anyone says) but the right actions done consistently will get you to where you're trying to go.

I been running an AdWords Express campaign with a higher end budget.  

Will the economy grow at 3% as promised in the campaign?  

@Alex Deacon I agree but I'm trying to implement a cost effectiveness strategy to find more deals while also running my mail campaign to find deals.Down the road,  I'm looking to have a VA do all the cold calls for me.

The campaign you've set out on now just floats effortlessly in earth's orbit.
