The number of 90% loan-to-value 2-year fixed rate products on the market reached a record high of 275 in September, moneyfacts data shows.
Comparatively there were just 196 products in September 2016 and 101 in September 2012.
Charlotte Nelson, finance expert at moneyfacts.co.uk, said: “This is great news for borrowers with small deposits who have felt almost ignored by the market, as not only have rates at 90% LTV fallen to an all-time low, but the number of 2-year fixed rate mortgages available has seen a 29% increase in just one year.
“A lot of the boost in deals could be down to the fact that borrowers may be under the impression that a 95% LTV deal is a rare occurrence, opting to save a little bit extra to put them into the next LTV band instead, and this extra demand is now being catered for.
“With lending at higher LTVs now more the norm, the 90% tier has become a key target for lenders who are looking for a new avenue in which to compete and stand out from the crowd, as other parts of the market start to become saturated.”
