First-time buyers accounted for 47% of all house purchase activity with home movers making up the remaining 53%.
Remortgage lending went up a year-on-year in amount borrowed, and increases in number of loans mean quarterly remortgage activity is at its highest level since Q4 2013.
First-time buyers in Wales typically borrowed 3.18 times their gross income, up from 3.13 the previous quarter but less than the UK average of 3.38.
The typical loan size for first-time buyers was £102,207 in the second quarter, up from £101,150 in the first quarter. The typical gross income of a first-time buyer household was £32,526 also up compared to £32,320 in the first quarter.
First-time buyers' payment burden in the second quarter was 17.7% of gross income being spent to cover capital and interest payments, down on the first quarter's 18.0%, and lower than the 18.4% UK average.
Home movers went up in volume and value quarter-on-quarter, and while number of loans remained unchanged year-on-year the amount borrowed by home movers increased to 2.77 times gross income, up from 2.75 the previous quarter.
The typical loan size for home movers was £126,000 in Q2 - substantially lower than the £160,994 UK average.
Home movers' payment burden in the second quarter saw them spend 17.0% of their gross household income being spent to cover capital and interest payments, a slight change from 17.1% in the first quarter, but lower than the 18% UK average.
Julie-Ann Haines, CML chair for Wales, commented:
"House purchase activity appears to have woken up in Wales after traditionally slower levels in the winter months. The uptick in remortgage is, in particular, striking as levels had remained relatively identical over the previous four quarters. With the current low rates of interest unlikely to continue, it seems that borrowers are now taking advantage of competitive mortgage rates before a rise."
