Why do you need to use an IFA? From a very jaded perspective they will only sell you a product that you could have found yourself and I think I’m right in saying that your first few payments will go straight into the IFA’s pocket.
If it’s a financial “product” you need, why not just trawl the internet?
(Last week our neighbour moved out to a big apartment, mortgage-free, in a swanky gated estate having made a small fortune helping people to reclaim the PPI insurance they were mis-sold…. by him and his mates in the 90s! About five years ago this neighbour was bankrupt but thanks to the commissions on reclaims he now owns outright apartments in Florida, Budapest and now Lancashire as well as two small houses he rents out in the area.)
