We have had buy to let for a decade now, one in Sheffield before, one in Scotland now.
It can make a return, but it is more work than a bank. We have made a return despite the massive downturn.
Currently our flat has made 11% return give or take (before the iffy tenant below), about to drop to a more normal 7% as we are buying our own house again.
I have just remortgaged as the market is not yet strong enough to make back our capital IMO, so we are going to give it another 2 years.
Currently I would get out if I could. We have had a very awful tenant experience, leaving us £3.5k out of pocket, or 18months gross profit. We also are too far away from the property now (we self manage). On top of that, the Scottish letting laws and paperwork are now crazy complex and loaded against a landlord. I am dreading another iffy tenant, who a council would support and prevent from being evicted and could drag out for months and months of unpaid rent – all backed up by a court. I have had enough. The risk is not worth the return anymore.
