The UK landlord's average portfolio is now worth £1.52m, according to new research.
The value of the average landlord's portfolio increased by 6.1 per cent in the first three months of 2010, according to Paragon Mortgages.
This is a jump of almost 2 per cent on figures in the same quarter last year, as well as the second quarter in succession to see rising prices.
One of the reasons that there has been an increase in worth may be down to landlords taking advantage of lower prices in the housing market to add higher quality stock to their portfolios, claims the report.
Property investors may be encouraged to invest more by the news.
John Heron, the firm's managing director, commented: "Confidence amongst the landlord community has grown in recent months and that is reflected in portfolio valuations.
"On the whole, house prices have been rising since the middle of last year and we know that landlords have taken advantage of a more fluid housing market to add properties to their portfolios."
The survey also found that almost a fifth (19 per cent) of landlords surveyed were confident that prices would rise.
However, Heron cautioned investors that increasing property prices would be dependent on the availability of finance.
