Kielce is a beautiful city, but one of worse in terms of jobs. Graduates usually move to Warszawa, Kraków and even £ódź fast after getting their diploma. The prospects for the city are that it will shrink from 200 000 to 150 000 in next decades. So if you want to invest your money into apartments, then better choose other city. But if you want to simply live there in your own flat and low salaries are not a problem for you, then check for example this website:
Swietokrzyskie Province is one of the smallest surface regions. The site has to many large cities (only the capital gained the status of county borough). Therefore, Swietokrzyskie report low rate of urbanization. The economy, which only to a small extent contributes to a total national GDP is mainly based on the steel industry, metal, machine. A definite advantage is its natural Swietokrzyskie attractions - including Holy Cross Mountains.
The average apartment price per square meter on the secondary market in Kielce at the end of September 2013 totaled 4399 zł. This is the lowest value among the four cities of the eastern provinces (Bialystok, Kielce, Lublin and Rzeszów were analyzed). Over the last year the average price of housing in the checked categories rarely exceed the threshold of 5000 zł / sqm and it was most often related to large units. In the third quarter of this year only 5-room flats exceeded this price.
As you see for 160 000PLN you can only buy studio. Perhaps 2 rooms 2nd hand apartment. Since it will be long term bad investment anyway, buy what you like. I think that 2 rooms is better than 1, but location counts too.
