When I pay down the loan faster than 30 years, the way I look at it is my principal payment is basically saving me interest expense. 

It it is just a straight loan (not fix and flip etc) then it boils down to underwriting and application time whereas a private/HML can close in 7-14 days or faster and a traditional bank will take up to 45 days.

Highest ROI, especially in markets that appreciate faster than inflation, is achieved at highest leverage.  

In my opinion, paying for a coach is going to help get you to where you want to go faster especially if you are brand new to wholesaling.

I can't find any evidence that would save money or pay off your loan faster. 

In certain parts of Texas the property taxes are raising faster than rents can keep up.It’s not talked about much, but rentals are not always a moneymaker, especially the first number of years.

Yes, with this comes more risk, but also more reward and ability to scale faster.

If you’re able to find properties that are under market value, then you can build wealth faster through forced appreciation that happens when you fix up the property at the beginning.

I would think you would need a pretty large bankroll to start with this as presumably you would take over any mortgage payments and maintenance and have no income coming in from it. 

Try to put as much value as possible away from the house and the storage buildings, to get faster write off.
