I know you want a number but it's near impossible to give you one. Here's why.
Prices depend upon a number of things with location traditionally being a huge factor. Other considerations are regions within the country, counties in a state etc. And then there is always the condition of the house and any environmental issues that exist. Being a 1955 house one of the first things one would look at is lead paint and/or asbestos, and the potential remediation cost.
If you have specifics on the more major factors your agent should at least be able to get you a range of prices.... and the caveat is it will be an estimate without a visit or some previous knowledge on the property. Sorry I couldn't be more exact for you.
