For personal loan you should show a greater salary to get huge amount of money as the loan. For car loan, you would only be given certain percentage of the car cost. For the house loan you would get more loan but you should buy the house without spending them on your personal expenses. Since the banks would not ask for any sort of security deposit for the personal loans the amount would be less. Since the property itself is the security for the mortgage loans there are chances that you could get these loans at a fast pace than the personal loans. However, like with any other loans you should undergo lot of verification process only after which the Rivingtons Mortgages would approve the loans.
You could first check if the property you are planning to put for mortgage is within the coverage area of this lender. When you have the property under the coverage terms, then you could also check what sort of credit score you have so that you could still maintain good credit score by taking the mortgage loan. Though you have the good credit score, one other risk you could have is with being self-employed. Soon after buying the house if you have left the job for self-employment then getting the mortgage loan would be tough. Also, when taken the mortgage loan but want to go for the remortgage to get more money than before or to take advantage of the interest rates you should be very much cautious about the pros and cons of the expenses that you would have to bear with for getting the house refinanced or remortgaged.
Though you may be worried about the lengthy process like evaluation of property value, legal opinion etc, the loan amount would be high and the interest rates on mortgage loans would be less than other type of loans.
