Research carried out by house-builder Larkfleet Homes and What Mortgage has revealed that many house buyers depend on help from family or other sources to finance their purchase.
A substantial minority (28%) of current house-hunters expect to receive some help with putting together the deposit needed to secure a mortgage - but most (64%) say they will have no assistance.
However, when it comes to the point of purchase it appears that not all the promised assistance materialises. Among those who have actually completed a purchase, only 22% say they received help with the deposit.
Those who did receive help with putting together a deposit usually 58%, obtained it from their parents - and grandparents assisted a further 8% of respondents.
A slight majority (51%) of those who received help are expected to pay the money back - but 46% are not and 3% are unsure.
Once they have a deposit in place, the majority of house-hunters appear to find the process of applying for a mortgage relativley straight-forward - 16% said it was 'very easy' and 41% said it was 'quite easy'. However, there were substantial minorities who had varying degrees of difficulty.
Among those who have actually completed a purchase, the perception of the ease of applying for a mortgage is even higher than among those currently searching for a house. A total of 74% describe it as either 'very easy' or 'quite easy'.
Larkfleet CEO Karl Hick said: "it is important that we understand our customers and the ways in which they finance their purchases so that we can see whether there are ways in which we can assist. One of those is to introduce potential buyers to independent advisors who can help them get the best possible mortgage deal'.
Joanne Atkin, editor of What Mortgage, commented: "With house prices so high in many parts of the country, it can be really difficult to save enough for a deposit on a home. If you do have to rely on outside financial assistance from parents, grandparents, other family or friends, remember that your mortgage lender will want to know where the money has come from".
