This is a brave thread to start on LL-hating guardian reading MN....BTL is a crime here because it involves making money out of a human need. It is ok to sell food, get paid to nurse and so on though. Go read landlordzone for advice and the horror stories. They will hand bad landlords their arse on a plate.
yes, you can make a profit - no point otherwise. MN oversensitivity disclaimer - most tenants are normal human beings and all goes well. But if you get one that isn't you are in for big big bills.
not easy money, but with inflation double and more savings rates you have no alternative if you don't want the money you worked for to vanish. I would LOVE to know of investments (not savings) that make 4% or more.
Be aware:
being a landlord is the ONLY service where you are compelled to keep providing it if the customer stops paying, and have to pay further to be able to stop providing the service. Get any paperwork wrong and no eviction.
a tenant can commit no crime related to the tenancy. Even dealing drugs in the property is not a reason for a speedy eviction. Landlords can commit lots of crimes, including harrassment. Oh, and if your tenant is imprisoned for something else you still have to go through the legals!
Tenant can smash the place to pieces, if you forgot to get malicious damage insurance there is no cover.
most policies exclude damage from illegal activity. Cannabis farm...
if your tenant wants a council house, they will be told to stay until evicted. They will be told to keep paying rent until that day. They will be liable for the eviction costs (£1k - £2k) but the LL will never see that. Most legal expenses policies do not cover this situation. The tenant does nothing wrong in not leaving until eviction. There are also lots of ways to delay the bailiff. Shelter will advise your tenant.
ditto if your tenant just doesn't want to go and stops paying. Don't chance it in London where it is a year's wait for the bailiffs. That said, in London any tatty mouldy dump will rent for a fortune. This is NOT the case elsewhere but no-one can see that because UK = London.
Government policies mean that BTL with a mortgage is probably not worth it now. Screwing down on nasty private landlords (while letting housing agents rent out shitholes, ditto for large corporates) is also great for hiding bad news; witness Hammond's IPT increase hidden in the autumn statement below the babble about agent fees. Great move, no-one noticed.
