Best options to refi a fourplex in Portland

[Finley Miller]

We have a fourplex in Portland that has a seller-financed mortgage on it. Its worth maybe $900-$950k and is at about 40% LTV. We hadn't refinanced because of the prepayment penalty on the note, even though the rate is not good compared to what's available now. Now the rates are low enough that it is probably worth it to eat the prepayment penalty and refinance. We'd like to do cash-out and it is currently owned in an LLC, in which it is the sole asset. I assume it may have to be converted to a TIC. The LLC has three members. My questions are:

1) Can we continue to hold in an LLC or would we be better off as TIC?

2) What type of rates/origination costs should we expect?

3) Any recommendations for lenders?  Some don't seem to have a big appetite for cash-out refi on investment property based on a few initial calls.
