People would find renters via local advertising to rent Christmas Week and make enough money to pay for a vacation to Hawaii and a month or two of mortgage payments. 

So far, they have all worked as advertised. 

I’m thinking about running an AdWords campaign for my website to try and generate more off market leads but I’m not sure what key words or phrases have turned out to be successfulAny input you’ve had from personal experience would be awesome!

My partner and I would like to ensure we are not advertising the property specifically but rather the contract.

With any type of mailing "campaign" you're going to want to plan  how long are you willing to continue to pay for mailers until you get a lead that you're able to covert.  

I am getting ready to start my first marketing campaign to go directly to the seller and buy properties and was wondering what your preferred avenue of marketing and budget is.

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.One thing to note when looking at the individual markets, you can make or loose money in any market.

What people are advertising as "Temple" seems to be rather loose nowadays, branching generously west, north, and east of Broad.

For example, my local REIA group is always advertising workshops on different strategies that Elite offers, as well as being part of the "fast-track/success" group so you can learn more, have more support, and really be successful in Real Estate.

Just a few of the many things to consider when optimizing keywords/ad words campaigns.
