What you describe makes perfect sense.

@Jay HinrichsYep, it's a promise to pay and has little to do with settlement, default on the deal, pay the note off or you could be sued.Going a step further, buy the place with 100% seller financing, close the deal, title goes to you as a buyer, then, an hour later, sell it for cash, payoff the note, there is no sneaky settlement statement trying to hid fees, perfectly legal and ethical with an informed seller.

However it I have recently adopted the "imperfect action is better than perfect planning" mindset, so no more lurking.  

It's perfect for Flippers and Multifamily investors.

As of now wholesaling seems to be the perfect route for me be that I am a beginner with little cash-flow and no credit. 

If you do not this is the perfect time to create one for the next lease agreement you use.  

I'm looking for opinions on finding a balance between keeping some money in the bank or paying off personal debt, low interest but freeing a lot of time and working as a safety net or a nest egg for the perfect deal to snap up or investing more aggressively trying to build a bigger portfolio but undoubtedly in my case sacrificing time.

Are they perfect for all the scenarios that investors encounter?

TCs manage the literal paper file.. they follow all the dates and make sure the agent is in compliance ( agents dont get paid if their paper work is not perfect in our area LOL) the TC is just an assistant who specializes in handling real estate paper work..

I think the 4 flex/ house hacking approach you too is perfect.
