There is a program that allows you to purchase up to 90% with no PMI. Unfortunately, I don't think there is a 95% CLTV program out there for Jumbo mortgages.
If you need further assistance, please feel free to shoot me an email.
Your challenge is finding bank/lender who will do a second at 15% up to 95%. If you can find a bank to do the second to 95% CLTV. BancCorp South can do the first. They may do the second but anyone who does a second to 95% will want a relationship with the customer.
If you are a physician then you can get physician financing up to 100%.
