There is nothing stopping you from incorporating and doing this yourself, as you would be subject to the same regulations as we are.
However, although the process of incorporation is not a huge burden, the administrative, accounting and legislative overhead in running a limited company is more than many landlords want, and in many cases takes away the whole reason they chose property as an investment vehicle.
If you have a smaller portfolio (under 5 properties) ARLA found that the added cost of running a limited company (including extra accountancy fees and the extra costs associated with increased administration) can eliminate any benefits of incorporating.
