There are two main types of Property Trusts available.
Property Securities Trusts invest in property trusts and property companies listed on the stock market. The returns are in the form of income from rental of the properties and capital growth if the trust/share price increases. This type of Property Trust is highly liquid as the investments can be bought and sold like shares.
The other type of Property Trust invests directly in a range of properties and can provide returns in the form of rental income and capital growth of the properties. Regular valuations are undertaken to establish the current market value and therefore any capital growth. This type of trust is not as liquid and usually has a minimum withdrawal period of 6-12 months.
