It all depends how the market is in Sweden at the moment. I'm guessing you want a better location, which is very understandable.
Here it's a bit flat. So we're very lucky we decided to do a part-exchange on our property and got given a good price. Like a trade in when you buy a car from the dealership. We would not have managed to sell our flat quickly and buy something else otherwise. (we're moving late April and only decided in February- you really don't get a faster sale than that)
Also, if you rent your home, you have to ensure you have budgeted for things you need, like landlord insurance (imagine you rent to someone that wrecks the place and the insurance refuses to pay) and agency fee, if you go through agency, otherwise it eats into your profits.
at least that's the way it's here.
Edit: There's pros and cons about living in a rented place. The good thing it's that it's not your property- when you want, you can leave, and you are not tied to paying a mortgage. The bad thing is also that it's not your property. So you are paying someone else's mortgage, and whenever they want, they can ask you to leave, to put the flat in the market... and then you are a homeless homeowner. There is such a thing, yes!!!
