Most portfolios are not planned; they accumulate. A first buy-to-let becomes three, then eight, each on whatever mortgage looked best at the time. At some point the structure itself, how the properties are owned and how the borrowing is arranged, starts to matter as much as the assets.
Personal name or limited company
The choice affects how rental income is taxed, how mortgage interest is treated, and which lenders will consider you. Neither route is automatically better; it depends on your other income, your plans for the portfolio, and how you intend to draw profit. This is a decision to take with an accountant and a broker together, before the next purchase rather than after it.
Why lenders look at the whole picture
Once you hold several properties, specialist lenders assess the portfolio as a single balance sheet, total borrowing, aggregate rental cover, and how concentrated the risk is, rather than each flat in isolation. Structured well, that can mean a single facility, one set of terms, and capital released to keep growing.
