A lease can be either for a set period of time, which means it ends on a given date, or it can be periodic, meaning it runs from week to week or month to month. If you intend to use the agreement, also check out the rental guide. Under the Renting Homes (Wales) Act 2016 (which is not yet in force for most), standard use agreements replace short-term leases guaranteed in Wales. We will prepare further documents as soon as this law is in force. If you do not have a secure short-term rental agreement that you currently use for your real estate, you can download the template provided by Farillio. Here you can download openRents AST Template for free. This is the lease we use with our Rent Now landlords.
