Ltd or Spouse for next purchase

Property Investment

Hi all, I'm looking to buy my next property. I've setup a ltd as so far I've only invested in my sole name, and jointly with my wife. Going forwards I had planned to purchase through my ltd, although I was concerned if I'd be easily able to get a morgage with a new ltd, possibly they'd want some assurance from me, fine.

My question is, should I buy in a ltd or should my wife buy the next one. Reason being, I'm a 40% tax payer, so no brainer that I use a ltd, but my wife is only part time paying hardly any tax, so well within the 20% range. Also as we've had a baby in the past 5 months, she may not go back to work at all....

I'm also looking into a form 17 to put the profits of what we have now into my wifes name, for her future as while we're both keen property investors, albeit small time, this could be a great career change for her. I'll be sticking with IT for a long time I think

Thanks
James
