Advice needed on land in the Wisla/Ustron corridor

I own a nice parcel of land in Cisownica, about 10-15 kms from the Ustron area. It has all utilities right on the spot, neighbouring houses have been around for 10+ years. It has great views etc...

I'm curious is Poland has an mls (multiple listing service) for homes/land for sale?

Any clue how much a acre/hectare in this areas goes for these days?

Thanks for any help..

I don't think there's a national Polish MLS; there are many private ones though. So it's a farmland or building lot?

It's a building lot for a house. Water electricity etc are all right there. It's the highest plot of land you can buy on the side of a mountain/hill.
