Out of sheer curiosity, where are you getting your facts that benefits drove the prices of rent up? I'm struggling to see the link beyond maybe if it's an area where landlords are heavily relying on councils paying out benefits and they will suddenly be told to take less/lower rent or find a renter who doesn't need the assistance of benefits they might lower rent to accept less money. I would be more inclined to see the cause/effect of rent being raised due to cost of living in particular areas and the amenities a particular area can provide less than just "benefits go up so rent goes up too"....
I've explained about HB and LHA above. It's your choice to read up on all the things that could be relevant to your business, or not to.
Also, I'm personally witnessing a lot of people NOT accepting benefits within my county because they see it as a risk to do so (so I see many people going on local buy/sell pages looking for anybody who will accept benefits for rentals and struggling to do so), so not sure a blanket statement like that can be applied across the board for the country.
As already said above, lots of landlords and tenants are on benefits e.g. Tax Credits. Some landlords are even claiming all sorts of means tested benefits under the old system, including HB/LHA, but will not be allowed to carry on having means tested benefits under the new system.
What if they, or you, go on benefits after the contract is signed by both parties? Two parties sign a contract, later on one party goes on benefits. Do you really think the relevant benefit agencies will tell the other party, that the other is on benefits? Have you heard of the UK's Data Protection Act? That's another REALLY important read for those in the letting business.
If you're speaking in terms of business plans, use a local, small business as an example. When prices for property rental/land taxes/VAT/etc. go up, the prices of good being sold go up. A landlord raising prices - while it CAN just be greed in some cases - is not always due to "not having a business plan for their business" as you often like to claim in our threads.
Not using a business plan for your business, or not reading all the laws that will apply to your business, is your choice entirely.
Using your analogy above, plenty of shop landlords end up with an empty property/shop, often for months or years, when they raise the rent and the tenant then moves out.
Definitely wouldn't disagree with a council telling somebody who's a landlord that they couldn't help while they still held onto a buy-to-rent.
What has a council got to do with benefit money?
This is the one thing I CAN'T get on board with. I don't like the idea that a tenant could just look up where I, as a landlord, lives. I don't have an issue with a letting agent doing so, but I don't like the idea that there could be a crazy tenant out there who decides they want to look at where I live. The fact that when they move out of my property, I won't have any clue where they are but they will know where I am unless I move home myself makes me feel unsettled.
You might be a crazy landllord and you know where they live.
It's the law that the tenant can have your home address if they ask for it. e.g. They might want to sue you and will need your address for the court documents, or they can pass that to a relevant authority to take action against you for failing to comply with the laws.e.g. Councils, Trading Standards (under this new law starting 1 June).
I gave all my tenants my phone number and address, so that they could phone me if a repair needed carrying out and then I would try to get that repair done by the following day at the latest. I can't understand these landlords and their repairs in a "timely manner" - just get it fixed.
A landlord friend of mine still gives his tenants a copy of his passport, as well as showing the deeds to show he owns the property, and his latest mortgage agreement to show it is a Buy to Let and he has the permission to let, and his latest mortgage statement to show he is up to date and not going to have the property repossessed by the lender. In return, he can see their passport/s to show they are a British citizen, or a copy of their BRP or EU RC, and their statement and wage slips, benefit award letter/s. It's a two way street.
