Yes, you can “save” interest by paying off a loan faster - SO WHAT?  

Loan Origination Systems (LOS): What works best for mortgage and private lending?

Please, no solicitations.Use the renovation/acquisition loan products that require 10% down on the purchase and you should be able to get a few going at a time.

I'm curious why you want a HELOC instead of a conventional loan in the first position.

@Jake Baker  You should think about a rehab loan if you are going to buy and hold.

@Peter Tverdov it depends on going wages in your marketplace.I would imagine labor costs are much higher in NJ than in MI.

Also there is no restriction on acquiring conventional loan on primary residence even if you have maxed out on conventional loan for rentals.

Many banks securitize their loans (bundle them together) and sell the loans to Fannie Mae or Freddie Mac, while continuing to service the loans, that is collect your payment.

My duplex - built 1989, 2,060 sf, 2 bed/bath, 1 year old roof, value if I subdivide (county already approved) and sell each separately $150k each ($300k total)Investor duplex - built 1995, 2,300 sf, 2 bed/bath, 5 year old roof, value around $310kThe investors initial request was for an equal trade and they would pay realtor fees, which I replied wouldn't be equal due to buying/selling costs (recording fees, title insurance, closing fee, survey, inspections, loan fees, 1031 fees, accountant fees, repairs), taxes would increase due to new sale price, I'd trade a 3.75% mortgage for a higher one, and I'm on the 10th year of a 30 year loan so resetting that to a new loan would restart amortization and pay more towards interest.

@Brian Rocha It’s clear why most lenders insist on including rehab funds in the loan, and all of our partner banks follow this practice for fix-and-flip loans to minimize risk and meet securitization standards.
