Playing around with filters should help me narrow down rather quickly till city level, after that would be more local resource based play and leveraging ones network.Keen to read more on this.

Myself I had my title company pull every NOD in the MSA which was 4 counties 2.5 mil people. create a spread sheet and they would up date it daily as new NOD's came in.they would give me address  lien position  tax information and lien judgment search.. having our title plants digitized and off shore allows for this data to be gotten in a few clicks.. then when I got my short list I would give them that list about 48 hours before the sale and they would do a date down for me on those..

You are looking to create the biggest spread possible so shopping around for the best rate and terms should be a priority.

Typically, Wholesalers get a property under contract and then remarket the property while it's under control to investors looking to make their spread and then assign the contract and get out of the way.   

This would be even more true of a house where the tenants really live in the property and spread-out big time.

There are 30 million people in Texas spread across a huge landmass.

This will narrow your shopping area then you can hunt for the deals. 

Diversifying can spread risk and offer multiple income streams.I once worked with a friend who was in a similar boat.

Hey everybody anybody know of a free spread sheet for numbers(apple) or open office?

I can literally arbitrage the spread between my existing mortgages and my Ally bank savings account.
