HELOC on 4-unit Investment Property

[Kyle McCorkel]

I'm in the Hershey / Harrisburg / Lancaster area and have a 4 unit property in Elizabethtown purchased about 1 year ago. Based on recent comps, I suspect I might have some appreciation in the property already. The property could appraise as high as $275K, and my current loan is about $174K (current LTV of about 63% if my calculations are correct).

My primary mortgage on the property has great terms (4.5%, 30 year) and I'd prefer to keep it in place.

Based on this information, and the fact that I would like to pull as much equity out as possible to reinvest, what steps would you recommend I take? Does anybody know of any local banks that might be willing to give me a line of credit based on the equity in the property? Can you give me an idea of what terms they offer (interest rate, but more importantly, LTV %)?
