This emerged in new research from Legal & General mortgage club's smartrcriteria tool, which tracks product searches from more than 8,000 advisers.
Searches for homeowners wanting to remortgage after just six months climbed by 30% in February - suggesting that rises in the Bank of England's base rate to curb inflation could be prompting borrowers to lock into low fixed-rate deals.
While many consumers tried to manage their mortgage repayments, strong demand from buyers also continued despite rising inflation and other costs - particularly in the buy-to-let sector.
Searches for first-time landlords continued to climb, rising by 23%, and searches for those with corporate lets grew by 28%.
As house prices continue to soar and rising energy costs hit affordability, L&G says borrowers are becoming increasingly reliant on financial support from their loved ones to complete their purchase plans.
Searches for those with gifted equity jumped by 119%, and searches from landlords with gifted equity followed this trend - climbing by 15%.
Searches by advisers for borrowers with gifted deposits similarly increased by 6%, perhaps suggesting that the cost-of-living squeeze has resulted in first-time buyers needing a bigger deposit for completion.
L&G's data also suggests that families could be looking to alternative options to either minimise their monthly outgoings or free up cash to help their loved ones with a deposit as house prices rise.
Searches for interest-only mortgages grew by 33%.
Kevin Roberts, director of L&G mortgage club said:
"The cost-of-living squeeze and rising interest rates are clearly driving borrowers to remortgage and lock into low fixed-rate products that are still available on the market.
"Others are exploring alternative means of managing their finances, perhaps by taking out interest-only mortgages.
"Whether borrowers are looking for alternative solutions or simply want to lock into a fixed-rate mortgage for the future, advisers have a critical role to find products for these borrowers that can help them keep their monthly repayments low, while ensuring they have a mortgage that continues to meet their needs."
Meanwhile, other new data shows that average interest rates on mortgages are at a five-year high.
The Moneyfacts UK Mortgage Trends Treasury Report found that the average rate on a two-year fixed-rate mortgage is now 2.86%, the highest level seen since 2015.
This is an increase from 2.58% this time last year.
Meanwhile, at 3.01%, the five-year equivalent is at its highest level since 2016.
This is the sixth consecutive month that these two fixed-rate deals have seen their average rates increase.
