No penalty or tax paid, property purchased, and once the 401k loan is paid back, i can use the exact same method again to purchase a 2nd.My only concern is how the banks/lenders see my 401k loan from myself.

Also, is there a certain method for where to post what once a property is under contract and you are looking for advice or feedback about a rehab? 

( I do plan to do the BRRRR  method but I also want to try and convert a Single family home to a multi family home or convert the  garage to an ADU if the layout makes sense.

The easiest method is obviously using an agent as they have access to this information quickly.

@Elisha ChoHi, one simple method is do Zillow search with keyword filter for "seller financing" or similar.Also podcasts about seller financing:https://pca.st/episode/4195700f-93c1-4a44-875e-93dd43d6868chttps://pca.st/episode/ed8f5283-79fc-4701-89e5-7a9fa915fc6e

As for the 20% down method, you could start using OPM to expand. 

@James Carlson i'm thinking about trying @Craig Curelop's "living room" method too. 

Analyzing the property using the BiggerPockets Four Square Method, I calculated anywhere from a 7%-36% cash on cash return on the property. 

It is added footage that already comes with the board (and sheetrock, trim and flooring later) new so why waste it?

I use the BRRRR method, and this can be done successfully in Durham - even from remote.
