Some 74% of landlords agreed that the buy-to-let market needs greater innovation, the research from BDRC Continental revealed.
Three in ten landlords who rely on buy-to-let mortgages said they saw no real difference in the buy-to-let products available on the market currently and 60% said that buy-to-let lenders do not consider their individual circumstances as a landlord.
The study also revealed that the average number of buy-to-let loans a landlord holds is 7.7.
More than one in four landlords, 28%, owned their letting portfolio outright.
A third of landlords have a mixed portfolio and 39% own their portfolio with one or more buy-to-let mortgages.
Of the 28% who own their portfolio outright 41% said they purchased their properties using previously invested funds, a further 23% purchased their properties outright using non-invested funds while 29% had fully paid off past buy-to-let borrowings.
Around 37% of landlords said they make a profitable full-time living from letting although the proportions increase with the number of properties held.
Some 11% of landlords with one property were able to make a profitable living from letting, compared to 38% of those with five to 10 properties and 72% of those with 20+ properties.
Mark Long, director at BDRC Continental, said: “According to our research it is clearly possible to make a full time, profitable living from private letting, and certainly those with larger property portfolios are more likely to be able to do so.
“Buy-to-let mortgage borrowing remains important for the majority of private landlords and our research suggests that there is still room in the market for providers to listen to their customers and provide a product suite better suited to their needs.”
