Though I appreciate the idea of finding online resources and studying them, I find that a curated, tried and true formula (if it works) is much more worth my time than spending time trying to find which resource works best and then spitballing the ideas until something sticks. 

@Dennis GallagherAs for the 50% Rule (where your expenses equal about 50% of your revenue) - I might argue that the flaw in the theory is you will walk away from many great wealth building opportunities just because it doesn’t meet the formula.

But then it was a nightmare of communication, we soon realized that we had to do a bunch of songs and dances to convince them to sponsor our deal, it took 4 or 5 days for them to make time to sit down with us only to tell us that we needed to schedule another meeting in another 4 or 5 days to get Tyler on the phone and let us try and convince them to sponsor us and by that time someone else was awarded the deal and we lost out.

I bet Baby Shark would be an especially annoying song. 

What formula or criteria do you use to decide whether to flip or to hold?

You get into bed with these big lenders and all the fine print its like the Paul Simon song there are 50 ways to default and they will find one.

Knocking off $4k for that additional bathroom let's say it's $170k ARV, looking at this for a flip and using the 75% formula and a $120k buy price that only leaves $7500 for a reno budget - I'm no expert but I'm pretty sure it'll take more than that!

What's the magic formula Bob?

Use the cash-on-cash return formula: (Net Annual Income ÷ Total Cash Invested) × 100.
