The best way to find a good Investment Realtor is by word of mouth.  

There was alot of trial anderror which put a bad taste in my mouth.  

This is a good question Me personally I have a small family business and one thing that I find interesting is that if you provide a good quality of work word of mouth is huge!!!

We found a great and affordable 3 bedroom home with tons of potential (unfinished 3rd floor, partly finished walkout basement) and could not be happier (especially at the killer price we get it for after some hard negotiating).

Would you have a mechanic work on your mouth just because he knows how to brush his teeth?

You'll be happier with the quote., again we can always run that, or if you prefer someone on the northside I see if I cannot find a referral.

The most effective advertising is word of mouth.

I have found utilizing the MLS, Craigslist, "Word of Mouth" and tax deed sales to work in rural communities.

Once dried out, they replaced sheetrock and repainted, evaluated the wooden floors and were able to sand and restain them (and are happier with the new color), and of course fixed the pipe/furnace.
