buy to let to new house advice needed please

Grimbo82

Hi,

I was wondering if anyone could answer some questions for me on the mortgage process. My and my wife currently hold 2 properties, one a flat which we currently rent out and another flat (solely in my name) which is on 75% shared ownership which we live in. We have currently just started the legal process of buying the remaining shares in the flat and plan to convert this to buy to let with another lender or get consent to lease if current lender (halifax) will allow. Flat is worth around 80k and i would have 57k left on mortgage with halifax but would own 100%. Our plan is to remortgage my wife's property to another BTL and then buy a house ourselves. (we would have 10% deposit). We have spoken to an IFA and he says our plans are feasible but I would like to know:

How long does remortgage process take?
When should myself and my wife apply for our mortgage to buy our house?

we expect buying the remaining shares to take another 3-4 weeks to finalise.

Any advice much appreciated.
