I went to the Public Records for you & took a quick look at some Conrad Weiser homes in your price point, and as a (VERY GENERAL) ballpark figure (and obviously only knowing the square footage and school district for your house), having looked at other assessments in the area, I think you should probably be looking at taxes between $3,000 and $4,000, depending on the condition, age, style, & acreage of your home. (New construction in Berks Co. is being assessed at 65% of sale price, so if you can find good comparables that hold up the $160,000 sale price of your house, you stand a good chance of getting an assessment around $110,000. Then depending on whichever part of Conrad Weiser you are in - i.e. South Heidelberg, Heidelberg, Womelsdorf, Marion, North Heidelberg or Robesonia - your taxes will vary due to the different rates for each district.)
I hope this info helps you out - I know it's a lot, the agent who helped you buy your house certainly ought to be able to help you with good comparables, but if you have any problems, please feel free to contact me and I'll help you as much as I can!
