Try Georgia's Own Credit Union. They go up to 95% for fixed and 100% for ELOC.
Here are some of the parameters if my memory serves me right:
Minimum score 700
Maximum loan amount: $250,000
Minimum loan amount: none
Fixed 15 year rate: around 10.99
Fixed 30 year rate: around 12.99
HELOC (ELOC): prime plus 1 for the first 6 months (check that for accuracy - I never sold those as they can be deadly).
You have to make sure that the first mortgage company will accept the second lien. Sometimes, it's better to go with a lender who offers both first and second combined.
They require loan approval on the first mortgage before they start the second loan. It can delay the closing by as much as 2 weeks. DTI max is 40%.
US Bank also offers either 1 loan with lender paid mortgage insurance or split the loan out. OMG!! Make sure your loan officer knows how to read US Bank's guidelines. They are very tricky and can cause you a heart ache.
