I have used Aaron Parks with Century 21 Realty. He is based out of Newark, Oh.
For a mortgage broker, I use Ron Beitel, Red Brick Mortgage, he has an office in Gahanna and one up around Polaris I believe. I have used Ron for 4 loans now, including the one he is doing for me now. He is great, he has been at it a long time, owns the company and you deal direct with him if you ask too.
Tell him Ron sent you!, I meet with him in the morning.
Good luck
