Are you trolling?
If you paid rent you would have a roof over your head for that time. Nothing to show for? You didnβt lose anything. You got exactly what you choose to pay for.
Of course you can borrow money and make a return in 10 years. No one is arguing that. That doesnβt mean making yourself a slave to a bank is a good idea.
Why would you think I donβt own a house? Because I donβt talk like someone who has a regretful mortgage?
