what credit is needed for piggy back loan? 80-10-10

Ivan, That is a question you would need to ask the lender you would plan on using for the loan. Sayig that not all lenders offer the 80-10-10 option, because of that you want to compare the 80-10-10 loan against just doing a 90% LTV Loan. Depending on your credit scores, you might also want to consider a single payment PMI option. Your lender should be able to discuss this option with you. For every loan there are always pros and cons, you need to carefully evaluate the loan you take.

Depends on the bank the lender will use for the 2nd. I just did one with a 660 middle credit score but banks and credit unions have different requirements. I would speak with a local loan officer and have them give you a couple of options so you can pick a loan that best fits your needs. Best wishes, Sean
