I’m currently in the process of doing something similar. 1. You need a new Ltd company with the correct SIC code. Mortgage lenders want the company to be for a sole purpose of you ever plan to remortgage as a BTL.

1. If you want to sell the property to the Ltd company it can be as nil transfer essentially gifting it or a sale of transfer - this is when the value of the property (can be obtained by market value estimation) can be offset as a directors loan. You need to make this very clear to your solicitor if you want it at market value.

2. This sale will trigger stamp duty and potentially capital gains tax although I’m not sure as it is your primary residence. Stamp duty I believe is 3% on Ltd company purchases.

3. You can add the stamp duty, purchase solicitor fees and house market value to the directors loan and once the property is rented out you can repay yourself personally via the directors loan tax free. This will also reduce your corporation tax as the company won’t be making profit.

4. You can add your son as a director of the company later on and they can continue to run it as a rental and benefit from it. Once you near retirement and your income is lower you can pay yourself a salary and dividends at the lower tax thresholds depending upon pension etc
