You do realise that tenancy is far more regulated on the continent? Landlords have a considerable number of legal obligations. If they try and weasel their way out of essential maintenance they'll swiftly find themselves explaining themselves to a judge. And there's security of tenure: none of this about being able to give two months notice to quit on a rolling contract. In most cases, the tenant gets to choose when to leave, not the landlord - and it's enshrined in law. Deductions of that deposit must be reasonable - and proven. That's what you want? Fine. Bring it on. That's exactly the sort of thing I'd like to see.
Insurance will protect your investment - and it's even tax deductible! You do have insurance, I trust? Otherwise, perhaps you should sell and allow someone else the opportunity to actually own their own home. Because, when we get right down to it, that's what you're doing - depriving someone else of the security of owning their own home in order that you can speculate on the housing market.
I rented a flat in Germany for a while, and shared another. I'd have no problems operating under their rules as a landlord or as a tenant.
I think this would get rid of many of the more shady landlords and agents and some of the sharp practice in the industry.
However I think many tenants would have serious problems with this regime, as we found for example when the cleaner came in weekly (all flats have cleaners, they are the landlords eyes and ears) We would get calls about the mess the flat was in, shirts not ironed, milk not in the fridge, clothes not folded, top not on toothpaste.
As for insurance, I have building insurance but not rental insurance as the rates are excessive
As for speculation on the housing market, if I sold the houses I'd then have to invest in something else. What would your prefer I invested in, Arms companies, very profitable at the moment ? Oil companies, nice bit of shaleoil in Canada at the moment ? Fruit companies employing workers for a dollar a day ? Clothing companies employing children ?
You have to put your money somewhere, you can no longer leave it in the bank (who will be investing in all the above), at least with housing I'm providing a service, I can touch my investment, and bar mass emigration from the UK, it will have some sort of value.
