Manufactured Home Equity

[JD Pierson]

I'm looking for a little beginner advice. I've tried searching some, but haven't found much in this area. My wife and I are trying to cash out some of our home's equity for investment purposes. We both have 780+ credit scores and based on an old appraisal from a couple of years ago look to be at about 50% LTV in our current mortgage (although we are contemplating paying for our own appraisal to see if the value has increased further). The issue we have ran in to is we live in a de-titled, permanently affixed manufactured home on a few acres. I've tried working with a mortgage broker, but the best he could do since it was a manufactured home was a cash out refinance for 60% LTV and almost double my current interest rate. So not a lot of cash out for a lot more money long term. The interest rate didn't surprise me, but the low LTV did. My questions are:

1. Are there any banks/institutions that are more friendly to manufactured homes than 60% LTV?

2. Is a cash out refinance the best product in this situation? I was thinking a home equity loan might be better, but again I'm still looking for a lender. 

I appreciate any help here.
