This is up from the 1,455 buy-to-let products available in May, data from Moneyfacts showed.
However, the overall market choice is still far lower than the 2,538 products that were available in January, and the 2,897 in March just before the coronavirus pandemic hit the property market.
The number of two-year fixed buy to let mortgages across all loan to value (LTV) tiers increased to 625 in July, up from 496 in May.
In contrast, there were 823 two-year fixes across all buy to let LTV tiers in January and 914 in March.
Among five-year fixed buy to let mortgages, there were 644 in July, an increase from 480 in May. In comparison to before the pandemic affected the market, there were 879 in January and 1,000 in March.
When it comes to those with smaller deposits, there were only 31 two-year fixed options at 80 per cent LTV and 19 five-year fixed alternatives available to landlords in July.
These are significantly higher than the nine two-year fixes at 80 per cent LTV which were available in May, and the six deals available for five-year fixes.
However, the deals on the market are limited in comparison to the 141 two-year fixed buy to let deals and the 150 five-year fixed deals in March.
On average, two- and five-year fixed buy to let rates have dropped over the first half of the year.
In January, the average rate of a two-year fixed at all LTVs was 2.82 per cent. In July, the average was recorded at 2.61 per cent.
The average five-year fixed rate was 2.61 per cent in July, down from 3.19 per cent at the start of the year.
Eleanor Williams, spokesperson at Moneyfacts, said: “The shock of the coronavirus pandemic and its resultant effects has been the latest event to impact the beleaguered buy-to-let mortgage market, following on from a number of changes over recent years that affected stamp duty, interest relief and capital gains tax.
“The mortgage market as a whole remains an evolving and complicated landscape, as the ongoing impact of the recent lockdown has affected product choice and rates.
“The increase in overall product choice and the fact that average rates remain competitive when compared to where we began this year may be early indications that this sector is starting to recover,” she added.
