Interest OnlyLet me know if this is this loan is doable and if you can help:Home value per Zillow $1,125,000 (10 Rodrigues Lane, Walnut Creek, CA) (My credit score is about 790)First loan $355,000 (3.25%)Heloc $451,000 (int only until 2016 – currently just 2.75%, then I must pay principal also)My concern is that if I leave the HELOC in place, I could be faced with a MUCH higher payment when I must start paying principal on it in 2016 or faced with much higher rates in the future. My goal is to lock in the lowest rates I can for as long as possible with interest only payments.I DO understand that the lending establishment considers it a REFI WITH CASH OUT if new loan proceeds go to pay off a HELOC so what I would like to do is the following:1. I will pay off the HELOC just before new first loan closes (so that this is not "cash out")2. Get a new first for 70% of value ($787,500), interest only, is this doable at 3%?email is the fastest and best way to contact me. I never answer the phone unless we have a pre-set call as I am always involved in a project. Those who use email will get my maximum attention, response and action. email@example.comNovember 15 2012 - US00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
