Jason, I was in the same situation. Cash is King, right?
I now have a credit card with the credit limit equalling that amount in the savings account though a credit union. Since you've been disiplined in the past (cash), pay it off as soon as it's due. It's easy to pay with internet banking capabilities.
NoSoup is THE MAN when it comes to
advice on credit and lending. There are many good folks here in tilted finace. I've learned a lot. Keep on learning.
