1. Self Certificate. Getting a self certification mortgage is the most popular option for taking out a mortgage if you on a low income. However in the UK it is worth noting that increasingly mortgage lenders do look into accounts. They may not be as strict as a conventional mortgages; but it will be difficult to justify claiming income far in excess of what you earn. However companies will vary in their strictness in this regard. Some companies actually advertise saying they are not interested in seeing your accounts. However if you do go down the route of self certification there are some things to bear in mind.
