Locating owner?

[Kevin Jackson]

Ive recently come a across a duplex thats listed as an townhome. One side is for sale for 11k. We havent been able to locate the owner of the other side. I am skeptical of buying it and getting it rent ready and nothings happening with the other side, both sides need reno. My questions are have any you guys done any deals pf this sort, would you move foward with the one side, and do you know of any ways to locate the owner. The taxes are up to date on the side in question but the realtor cant find out who the owner is. Any advice?
