Purchase BTL in Personal Name or LTD?

Tax Planning and Financial

Should a new property be purchased in personal name or in LTD name like a Special Purpose Vehicle company?

I'm looking to purchase a new property, extend it for a year then later either renting out or sell it. like converting a 2 bed property to a 5 bed.

I understand when purchasing personally, we pay less tax on the overall gains however there are costs related to mortgage interests that are not wholly deductible from income. I'm a higher tax paer.

Is there any tool where I can clearly compare which route I pay lex tax for both scenarios of keeping the property and let it out OR just selling it.

Corporation Tax

Income Tax

Capital Gains Tax

Dividend Tax

Deductibles

etc.
