Mortgage rates are forecast to bottom out around June 2009. Short term rates could get as low as 5.50% with longer-term rates getting down to around 6.00%-6.50%. In my opinion that means taking a six month fixed rate now at 6.50%-6.90% is the best option. In six months you can then look to split your mortgage into multiple fixed rates and spread them over 3-5 year fixed terms
