Thanks for responding Chris. I guess I should've gave more details, so Here it goes.
I have three Rentals that I had bought in 2007 before the crash. I refied them in 2013 with a lower interest rate of 4.25% on all three with a 30 yr fix. For the passed 10 years I have been paying the mortgages and having a positive cash flow on all of them. I'm wanting to find a way to pay them off more quickly so I can use the equity to purchase more houses. I'm looking to retire from the Fire Dept in about 6 years. I was thinking of using my 457K to payoff all three houses so I could buy more real estate. By doing that I will take a 25% hit in taxes by withdrawing that money(Ouch).
Doing some research I've discovered HELOC's. With my research there are some things I don't like about HELOC's. Some people would say to use it like a checking account and deposit your paycheck in it to pay bills. I'm not sure I like that idea. I keep my business(rentals) in a separate checking account from my personnel checking. That is how I like things. Once I payoff a mortgage with the HELOC, can't I just use the HELOC like a credit card to payoff it off out of my business account? I've talked to my accountant and she would rather I do it that way instead.
I hope this gives you guys a better understanding. Any input on HELOC's would be helpful. Pat
