was able because it was only about 50thousand in 2003 yet i had two jobs,
That was in 2003 before many poles started sending GBP back home. You'll be lucky to pick up a bedsit (just below 40m2)for a 100 000zł. Try going to PKO or BZ WBK with a minimum salary job plus a part time and apply for a mortgage to buy a flat and see if they will approve. How in the world will you pay back the mortgage, fees and intrests if you're being paid 984zł NET. The only loans that all the banks are quick to approve nowadays are the ones for buying used cars +/-20 000zł.
It's never easy to get a mortgage in any country mate, especially these days. If you're still in the UK and you wanna come back and buy property someday just make sure you have a deposit of at least 40 000zł.
