This starts with establishing your Why and deciding which side of the cash flow quadrant you want to be one, the left side as a employee or self employed individual still in the rat race, or the right side as an investor and business owner with systemic passive cash flow.

Has anyone offered all cash then immediately refinanced to get the cash out? 

There are conventional loans as well with low down payments and the PMI falls off once you reach 20% equity.In this higher interest rate environment, lower down payments does make it harder to cash flow, so just keep that in mind.

Also, my first house hack was a bad buy imo, but now with both units rented - my cash flow is 400 bucks per door, which is sweet. 

Cash flow is beyond exception from medium term rentals.

I do not have that much cash sadly, but I was curious what your guy's thoughts are on financing that amount. could I get a decent loan for it?

Hey guys, Ofcourse I know you all have the capital to buy properties for cash, but what about the after sale?

if you don't, you could be way over and that will mess up your whole strategy of a positive cash flowing unit.

It has been a mix of 1 Conventional, 2 DSCR, 1 Seller Finance, 1 Cash out Refi and 1 Fix and hold.
