The state had 207 new home loan commitments by first home buyers during the month in original terms, the Australian Bureau of Statistics estimated.

First home buyers' share of the market in Tasmania was slightly lower than their share nationally, according to two new measures published by the ABS.

Overall, the state was estimated to have had 765 new housing finance commitments for owner occupation, excluding refinancing loans, during the month.

That was down by seven from the previous month.

The total included 79 loans for the construction of dwellings and 40 for buying newly erected housing.

Nationally, the number of loan commitments to owner occupier first home buyers decreased by 0.9 per cent in November in seasonally adjusted terms.

That followed a 0.4 per cent drop in October.

It was the first time numbers had fallen in consecutive months since January 2019.

Australians tightened up on personal finance in November, with the value of fixed term loan commitments down by 1.4 per cent.
