Advice Needed - 4 weekly rent (HB) and what scheme for deposit ??

Hi

Not sure where to post this but here covers one area.

I am about to start a new AST, i noticed there was also an advice bit with it about 4 weekly payment...I will be receiving this via HB.

Do i put 'tick the box' for 4 weekly ??

Also regards to the deposit, i understand i have 30 days from start of tenancy to sure it BUT it is asking for details of what type on the AST ?

What is the best scheme, think there are only 3 options and then custodial or insured.

I am also pretty sure there is a discount for one type by being an RLA member ?

Anyone advise.

Thanks
