Private real estate fund managers have more than $250bn (€225bn) in dry powder, or unspent committed capital for investments, according to Preqin.

A buoyant fundraising market has provided managers of closed-end private real estate funds with significant capital, Preqin said. The figure is up 37% on the $185bn at the end of last year.

Opportunistic vehicles have the highest amount of capital available to invest globally at $100bn.

Andrew Moylan, head of real assets products, said the level of uncalled capital available is a reflection of a strong fundraising environment, as institutional investor confidence in real estate continues to increase.

β€œHowever, with increasing valuations and intense competition, finding attractive opportunities to invest this capital in the coming quarters is likely to be a difficult prospect,” he said. β€œFund managers will have to work hard to find value in an increasingly crowded marketplace.”

Moylan said there is a competitive fundraising market, with 416 funds currently being marketed.

β€œThis will make raising capital a challenging prospect for many over the second half of the year,” he said. 

The second quarter of this year saw 47 real estate funds secure $26bn, bringing the 2015 total so far to $60bn. Preqin said the figure is the second highest for a half year since the financial crisis.

The majority of capital is focused on North American real estate, with $133bn focused on the region.

In the second quarter, 22 North America-focused funds raised a combined $10.3bn, while 11 European offerings raised $12.8bn. A total of $2.5bn was raised by Asia-focused funds and $400m by funds investing across other regions.

Preqin said 62% of funds reached or exceeded their target size in Q2 2015.
