2) Are there any other free online sources where I can post my ads or contact motivated sellers other than Craigslist?

The seller lives and a different state, so I believed she was motivated to sell.

Motivated buyers are looking to shorter term adjustable-rate loans, buy-downs, and closing cost allowances to offset the high rates.

Motivated sellers only?

Those of us who carry a full time job still have a lot we can dedicate towards other interests (such as real estate investing), so long as we have the motivation to get through it.

I say go for it. if your a go getter and motivated and a person that is not afraid of work, you can succeed at a part timer. anyways with modern technology, no one will know your a part-timer. you can call buyers, agents, brokers, anytime of day and they will not know that your doing it while working another job at the same time.

negotiate, are they motivated?  

There are resources you can find that lay out different methods for building up your sphere of influence, but I personally like catching up via phone, meeting up for coffee, or doing something fun as a touch point.  

Everyone has a quote or motto that keeps them motivated and moving forward.

Driving for dollars, motivated seller.How did you finance this deal?
