It depends on the value of the home, but it’s often around 50% ltv for anything over 350k. Of course, a rate refi is different than a cash out or equity loan.
If you’d like more specifics I’d be happy to talk to you about it. Just send a pm.
Fannie Mae will go to 85% on single family non-owner occupied. The loan size can have some adjustments to that number a bit, but for the most part, you should be able to get 85%. PM me if you want to talk more about specific details.
