I am sure most of you are aware of the method I am referring to.

This is your market for lease option sellers and there are thousands of them in every city in the US, you just have to know how to market for them.It would seem to me that the benefits of getting paid 3 times (option deposit, monthly cashflow and back end payout)  on a house through sandwich lease optioning is much better than just getting paid just monthly cash flow by using the method you are describing.

My main concern is the cash flow for the first scenario, but the BRRRR equity looks great.  

One way to do this, which is the method I currently use, is through "House Hacking" and AirBnB. 

From the owner directly with a copy of their statement or from their credit report (Assuming it's not charged off or subject to BK) and both methods require cooperation from the borrower and, at least one method puts you into tremendous legal trouble if you obtain their credit information without permissible use to do so (Like buying someone's credit report on line)?

Its the Brrrr strategy as they lovingly dubbed here on BP.

I took a deeper dive, and listened to may of the podcast episodes that Sean had put out, as well as the BP podcast episodes where the various methods of wholesalers were revealed in interview after interview.I found many similarities among what I'd read and heard on the podcasts:Direct Mail is a very popular way to goYou'll likely need to spend thousands in marketing dollars (most likely using yellow letters and postcards) to get the deals coming in to youOnce you get one deal, the rest snowballCommit to one marketing strategy, bandit signs may work but they tend to be the least favored here on BP (due to their "uglying up a neighborhood" and the fact that many times they are illegal and get removed)So I get the general gist of this but the questions I still have unanswered are:How does one know what is the right legal language to put on contracts?  

We got our first duplex using this method.

There is no secret method to finding deal in TX.

Again, i used the percentage method as a first go round.  80x12x10 = $9,600So to sum up, my GSI calculation for the deal So based on my new #s, it looks like the purchase price should be around the $400k mark, not the $650k mark based on the provide cap rate.Now reviewing the pro forma #s in a rental calculator, this deal does cash flow (assuming 20%down and financing).
