Investing your finances in short term things is one of the concepts you have to think through. It's another thing to set it for bigger ventures like properties. When putting money in purchasing properties for lease in the future, you should acquire a tenancy agreement template to model your contract from. The tenancy agreement is a signed contract between the landlord and the tenant. Accelerated possession procedures require a rightly drawn agreement. For claims on housing benefit, the tenancy agreement is essential to the tenant as it will be proof of their tenancy so the contract is beneficial not only to the landlord but for both parties.
When you find yourself considering going into business together you might want to consider how you are going to protect yourself in the event of a disagreement. If you are not planning to form a partnership you can always use a joint venture template to draw up an agreement that will protect all those involved in the venture. Considered a legally binding contract, you will find that when properly filled out this document will leave little for any errors or the type of misunderstandings that can cause what is otherwise a good, solid working partnership.
