ARLA has said it is totally opposed to the introduction of rent controls in Scotland.
The body has responded to a consultation on the Fair Rents Bill, which seeks to cap private rents across Scotland so that annually they cannot rise at over 1% above inflation.
ARLA says in its response to the official consultation that rent caps will reduce supply and have a negative effect on housing quality because landlords will have less money to reinvest in their properties.
It said that existing provisions, within the Private Housing (Tenancies) Act 2016, allowing landlords to raise rents once a year, are sufficient.
The response says that ARLA is already seeing fewer landlords entering the market and more leaving.
ARLA also says that tenants will suffer because of less choice in the market and poorer quality of housing.
It calls on Scottish MSPs to consider the historical impact of rent control before making any decision on the proposed Bill.
Rent controls are favoured in England by the Labour party and the Mayor of London.
