Hello Hello , I am really eager to start my first deal within Wholesaling, however there are a couple questions i need answered before i can take action such as

- Is the contract and laws the same in the Uk as US

- Say the property has an existing mortgage or other things attached to the property how do you sort that?

- 

As a disclaimer: I have no idea about contract laws in the UK. In the US, when mortgages and other things are attached to a property, it will be found out by the title company when they do their research. The mortgage gets paid by the title company when funds are dispersed at closing because the mortgage company has told them the payoff amount. Same thing goes for other liens or encumbrances on the property. 

You should talk to a UK attorney about how it works over there. 

Good luck!
