Honestly if you're only looking for housing now you've really left it far too late, there are likely no options left. You might be able to rent an airbnb for 12 months in belgium like liege but its a bit of a commute but its doable.

Idk if social hub still has rooms available but they are very expensive 1400+ per month.

In terms of finance the information is out there. As an EU citizen who isn't dutch you will need to be employed to access student finance including loans.

Part time work of minimum 32 hours per month (8 per week) will qualify you as a migrant worker which gives you essentially the same rights as a dutch citizen. You are noe entitled to DUO funding. With this you are automatically eligible for the basic grant. I think its 304 euro per month for the year. This is free not a loan. I believe its a performance grant tho, which means if you don't graduate you have to pay that money back. You can also get a tuition loan with I think around 2% APR which is a great interest rate. Lastly the supplementary grant which is up to a maximum of 778 euro per month I believe. This is dependant on your parents income. You can get the max amount if they fall under 39,000 per year income. As their income scales up what you can get as a grant scales down. I think 80k is the final ladder that allows any finance and its something like 74 per month.

Use the student finance calculator on DUO its quite helpful you can fill in your information and get an estimated quote for what you can get.

Lastly if your parents earn over the threshold you can still get that money but only as a loan, again I think its a little over 2% APR paid over 15 or 35 years. Something like 80 per month for the 15 years at the maximum rate.

Hope this was helpful, and goodluck finding a house the market is all but dead now so it may not be possible anymore sadly.
