Should I use an LLP of simplicity of CGT and IHT?

Tax Planning and Financial

I have an inhereted property which I manage for my mother-in-law and currently income and outgoings are mixed with her personal finances so looking at whether we move the beneficial interest to a LLP structure with an initial directors loan of (say) £10k to have a float in the accounts. Income and outgoings would then pass through the LLP whilst my mother-in-law retains ownership (for now although looking at adding her two daughters one being my wife as joint proprietors).

Whilst there is the possibility after 3yrs to incorporate I would gues we would struggle to justify the 19hr/pw requirement being just a single dwelling.

The end goal being we are trying to pass the property to the two daughters on the death of my MiL as a going concern and then further onward to grandchildren on death of daughters and spouses.

What I am trying to work out is:

1) Does the above make sence?

2) Can we run a business account via the LLP for transactions and purchases relating to the property

3) Is the above efficient for CGT and IHT planning?

4) Can the LLP directors (including me) sign leases and legal documents as beneficial recepients?

Any help much apprecited
