The amount of downpayment requirement insures buyers having "skin in the game". 

You will need to have the full amount you’re willing to pay.

I can pay for all my problems using the cash flow from my current rentals.

Even introducing a moderate amount of debt and purchasing another, OR exchanging out of the existing into a larger higher yielding property type with some debt.

And right now, homeowners across the country are sitting on record amounts of it.Here’s a look at how that equity could be a game changer for you, and why it’ll flip your perspective from “Why would I move right now?”

Pay cash.  

I'm hesitant to give up my conventional loans on the next cash out refinance for DSCR loans.

It costs the same amount to replace a roof or furnace whether the house is worth $300k or $30k (assuming a similar size).

While I’ve flipped a fair amount of houses, Iv never done one one while living in it.

The structure will depend on the down payment, quality of borrower, terms of note, your cash out of the note sale needs, and other factors.
