World's biggest first world problem coming up.
My partner and I own our flat in London outright. Never had a mortgage - we're incredibly lucky, saved super hard and had help. We have one DS (2) and want to try for another. We've outgrown our really lovely home and have found a house we want to buy. We're both self employed and though our earnings can fluctuate a little, we earn enough to take on the smallish mortgage to fill the gap.
However, the mortgage broker, the estate agent and my accountant have all advised us to rent our place out, take on a bigger mortgage (without selling our place we could only afford to put up 10% as profit) and use the rent to pay the new house off. Our flat is valued at 650K, rental value of around £2000 a month. New house is 900K.
We're super risk averse. Having never had a mortgage, this feels like a huge thing to take on. And I thought we'd probably be subject to paying quite a lot of tax on whatever we make from renting. But everyone seems to be advising us to do this.
OR - to mortgage current flat up to hilt, rent it out, buy new place with smaller mortgage - but then that seems confusing?!
Does anyone have any advice? WWYD? TIA.
