Ok now that you have a good job with a good salary, you finished your studies from years and finally you have took decision to leave the nest, looking for your space to say "welcome to adulthood" there are some questions to do to yourself:
Do you want to buy or rent?
Which is your budget? Be realistic in this point, studying all your financial documents, ask for bank counseling
Where would you like to live? in the centre or in the country?
Honestly everytime Iìve talked with a friend that was looking for an apartment/house I always suggested to go to a real estate agency, because he/she will became a sort of second you, understand your real needs, know accurately market and real worths of houses/apartment and helps you for other things.
When you meet realtor for the first time you need to be absolutely sincere about your budget, because if your budget is X a good realtor will show you good deal also under X budget knowing exactly your real possibility, while if you say that your budget is between X and Y is normal that realtor shows you all places near Y budget- realtor earn a commission on sale/rent- but there is the risk that you will fall in love for a place that you can't afford. Be honest and a good realtor will offer best solution at best price.
Where you would like to live? In the centre or in the country? Ok if you are opting for rent in my personal opinion is better stay in the near or work's place, because it permits you to stay in good location -considering that most offices are in the centre or in a walk -bike distance from it, this coul save you money on trasportation and this isn't a permanent solution.
While if you are opting for buy is better looking for perfect solution, usually it could be your permanet solution and have a backyard worths every cent spent on fuel is your decision. If you find a house that you like but you're unsure if that will be permanent place is better to opt for rent option so you can understand if you can live there forever.
First step after questions is looking on the market and see what it is offering via web, real estate free press, real estate agencies and see if there is something that capture your attention. Then book appointment to visit places, but don't stop never at first place, also if sometimes it wins on alls, but visit at least 5/6 places and then decide your favourite 3, compare everything: location, neighborhood, price, if there are work to do (and there are little difference between buy and rent). Thne when there is a winner book a second/third visit on the "place" and in another time of the day, best solution would be visit it when is raining because if you like a house when sky is grey is sure that with sun it became wonderful.
You could ask why you need a realtor? Nobody is saying that you can't do it alone but is a stressful work, there are several burocracy documents to fill, do burocratric controls before buy/rent/sell and most of time realtor helps you to negotiate price and all saving your time.
