If you're young and haven't inherited a property from your ancestors, chances are that you're forced to rent. Personally, I've been renting for over 6 years and have been living with my girlfriend for the last 4, sharing rent and utilities. Overall, we've both spent over €25,000 together, and after spending all this money, you're practically left with nothing and may be subject to looking for a new house at any moment.
The average rent for a one-bedroom apartment is between €300 and €400 at best; thus, I was thinking that taking a loan is as costly as paying rent per month, but after 15-20 years, you end up with a house. My main concerns are the following: First, if you're in a long-term relationship like myself, you can never be 100% sure that you'll be with that person in 20 or 30 years from now, which might prevent you from opting for a loan. Secondly, you need to be certain that the location or city of the property to be bought is convenient for future job offers and so on. Thirdly, because a loan is a many-year commitment, there's no guarantee that you'll be able to afford the monthly payment 15 years from now.
On top of that, finding the ideal house as a renter is almost impossible; there's a lack of housing, and rents are extremely expensive and unreasonable at the same time. We had a difficult time finding a house recently, and it's far from ideal. There is now a new government-funded loan program that is about to start, funding up to 75% of the loan interest-free while the rest is funded by private banks and is subject to a relatively low interest rate. This led me to think about taking a loan and purchasing an average two-bedroom apartment, but I have the concerns that I voiced earlier.
If you find the right mix, renting can be a very valuable aid and work out quite well. When you're young it gives you a huge amount of flexibility, which can be very useful as you figure out where your career is going and whether you need to be in a certain location to maximize your salary potential. If you're jumping around every 2-3 years making your way up the ladder, being tied to a geographical location while you pay it off could actually reduce your lifetime earning potential. You can also use that flexibility to increase the gap between your bills and the eventual deposit that you might accrue towards a house purchase in the long run, if you commute into New York from the suburbs and earn a mega salary - it opens up huge possibilities for relocation in future.
