I think Shaun Weeks response was very informative, insightful and great advice.
Me myself, I am pro heloc. It can simply be used as your new checking account to pay off the monthly interest payment and to pay down the prinicipal all at the same time without having to come up with any extra money.
What I mean by that is... With the heloc option you and your wife can take all of the money that you earn every two weeks or every month, however often you both get paid, and put it all in to your heloc account. The first 200 (as the example given) will go towards paying off the interest for that month, then the other monies that you both deposited will be a principal payment. It goes directly towards paying down the principal balance. That money sits there, working for you by paying down that principal and it works for you by lowering the principal, therefore lowering your next month's interest payment simply because you now have a lower principal balance on the heloc. This happens every month might I add. Another thing I enjoy about a heloc is, if you need the money again for any reason at all in life, it's there for you to utilize. With a cash out refi you have to go through all of the paperwork again to apply for another loan and pay closing cost fees all over again and start all over from scratch on your 30 year mortgage getting you nowhere close to ever paying off your house and owning this asset. Well, no closing cost fees for you to pay on a heloc with most financial institutions.
If it's sounding a little weird over the text I'd be happy to break it down for you over a phone call if you'd like. Just reach out to me through a pm and we can chat. I'd like to add value to your situation if I can. That's what bp is all about right...
I hope this made sense.
Happy Investing...
P.S.- I forgot to mention... That the draw period is 10 years in most cases meaning you have 10 years to draw from this account and utilize the money any way you choose and you have that long to pay back the 50k with the terms of interest only before the pay back period hits with interest and principal payments, but you can refi the heloc at any point before that, just as you would a loan. Simply do the heloc process over again and your 10 year draw period is renewed where you can pull from your heloc and utilize the money at your discretion with interest only payments.
But the way that I'll show you to utilize your heloc account you're simply leveraging your paycheck to be the monthly interest and principal payment without having to come up with any extra money. The account should come with checks and a bank card so you can also pay all of your bills directly from this account. The interest accumulated on a heloc is based on the daily balance. So the longer your money sits in there without having to be disturbed, the less interest you pay when the bill is constructed.
Once again I hope this made sense. If not, just pm me.
