Refinancing (without pulling out equity/changing your rate) does nothing to help you pay it off quicker. 

Use the LOC to move quicker but you still need to refinance to pull equity out of all your properties.

Focus on building relationships with people on here first, then eventually you'll get your answers quicker.

It's a lot quicker and cheeper than doing it yourself!

@Nick Versetto Would you say that if a property didnt need rehabbing that the turn around could be quicker ?

Sounds like the wholesaler didnt need to wait on any paperwork and submitted a better offer quicker.

We both own a couple 3 family houses, but want to try our hand at flipping to gain wealth and begin scaling at a slightly quicker level.Thank you,-Ben

If you are able to pay it off right away and start throwing money in your savings account for the flip project in the near future, you will be able to build cash that much quicker to put that money down and it will free up cash to help you pay for holding costs of the flip if you need it. 

Based on your argument for "quicker" money what would be the reason investors buy $100,000,000 office buildings in San Francisco at 5% cap rates (where there are actually analyzed cap rate comps)? 

The 3 bdr will likely be the cheapest rehab for you, initially I'd lean that direction due to costs and the payback will be quicker.
