The Association of Residential Letting Agents (Arla) has revealed that Investors have opted to buy more property over the last year.

The study indicated that the average residential landlord investor has boosted their property portfolio from 6.3 to seven homes in less than 12 months.

According to the survey, buy-to-let investment has almost doubled in the last five years, with the average number of properties per landlord increasing from four in 2004 to its current level.

A representative Arla, said: "Low interest rates and proportionately higher rental yields are making the buy-to-let market attractive again to experienced investors."

The 0.5 per cent Bank of England interest rates referred to are expected to be kept at the same level for the rest of the year and most of 2010.

Indeed, many economists are predicting that the cost of borrowing will stay at this record low throughout next year.

Oh why did I agree to high fixed rates! I have missed out on some juicy profits this year!
