Just pay the 30 year like a 15 to pay the principal down faster. 

Just pay down the loan faster. 

I would want to keep it, but we will be able to accelerate faster by selling it and taking the cash.

Your information will be setup in their system so that a new offer can be prepared, signed and submitted much faster than starting all over each time. 

The other thing to consider is that the city I live in is really incentivizing people to buy and renovate the old houses so even though it is in a historical district you cant go a block without seeing another renovation happening- the city is really pushing permits through faster than one would expect. 

Perhaps pay down your principal faster by adding an extra mortgage payment or two each year.

@Brian Garrett I see I've been looking at it totally wrong, I thought focusing on one could help us scale faster and ultimately grow that portfolio quicker.

I received a referral credit towards my rehabs, and then quickly realized I could wholesale and flip to create cash quicker to then purchase buy and holds faster.  

If the property is cash-flowing (however you account for your own unit) then I personally wouldn't pay down the debt faster than scheduled since right now as that takes away from your savings rate and next deal (potentially).

I want to buy and hold properties for long-term/passive income but he wants the two of us to flip a property so I can start my own bankroll and have cash to invest in future properties.
