Kicking myself for not growing our portfolio sooner but better late than never I guess.Here's the thing - We don't live in the US, my husband is a US citizen but since he hasn't lived in the US for many years he has no credit history.Now comes the fun part - we are in a lot of debt where we live (like $115k in loans).
