I own and rent. I own a house worth about £300k with a mortgage of £140k. The mortgage repayments are £500 per month. I wanted to upgrade my house to somewhere larger in a nicer area but didn't want to wipe out my savings to raise a deposit. So I made the decision to rent somewhere instead. It feels like the best of both worlds. I get all the upside of a big house without any liability for something going wrong (boilers, high end kitchen equipment, etc). I've rented the house I own to some tenants and the profit from the rent I make goes towards my rented house. Best case scenario - one day I'll own my old house outright and continue to rent. I might even buy another house to rent out at some point. Worst case - the market goes tits up I stop renting and return to the house I own where my mortgage is very affordable.
