It's true that interest rates can and often do vary from day to day which is why it is very important that when you find the lowest rate that you can, that you lock it in, even if you aren't quite ready to buy yet. Interest rates on FHA home mortgage loanswill also vary depending on the type of mortgage that you get. For instance, adjustable rate mortgages (ARM) may have slightly lower interest rates that fixed rate mortgages. What you have to look out for with an ARM is the possibility that the interest rate may increase significantly quite suddenly, leaving you with a much higher monthly payment that when you first started out. With a fixed rate mortgage, your interest rate will remain the same throughout the loan term. Your mortgage rate will also depend on how much of a down payment you are planning on making. With FHA mortgages, it is possible to finance up to 97% of the total loan amount but the more you finance the higher the interest rate will be.
