...been there, done that ...you're not the first and certainly not the last so don't go kicking yourself too hard
...long and short is yes and no ...it all depends on what you haven't told us
...you can get a mortgage with as low as a 580 Fico if there is no recent negative on your reports and the rest of your credit profile meets the lender requirements
...but you will certainly pay a higher interest rate and the choice of lenders and programs will be greatly restricted
...thing is, you've learned a lesson the hard way ...don't do ANYTHING with your credit, other than repairs and paydowns, for a year before applying for a mortgage
...suggest you jump over to the gardening thread and read up on how others are managing that discipline
...then take a deep breath and start contacting mortgage brokers ...there are several who frequent this forum ...and let them find a lender who will work with you
...or put the mortgage on hold until you're back above 640
...hth
