Dayton Ohio property tax and realtor recs

[Johnny Weekend]

Hi everyone, 

can anyone comment on their expenses with property taxes in Dayton. Will they get reassessed after the sale? I tried calling the assessors office but it is just a long hold. 

I calculated it as 100k market value then 35% off that then 116.5 mills which can be about 4k on a 100k property. 

Also any recommendations for a realtor and property manager in the city?

thank you
