Now, this is not a fool-proof plan; although, I know people in this business for 30 years and have done it the same way I have and have yet to see a claim.

Rents stagnate and do not keep up with inflation, utility companies if landlord pays water etc. can raise water and sewer rates even with no leaks and eat into returns.Again I do not want people thinking multifamily is fool proof and can't lose proposition. 

You're looking for a simple formula that doesn't require a lot of work and is foolproof. 

I am sure it will need tweaking or adjusting as no "plan" is ever fool-proof.

And even that isn't fool proof but hiring someone who has no references is just too risky these days.

Entering the house-flipping business requires having a careful decision and foolproof planning.

This method is a good formula to quickly vet a deal, but not foolproof. 

Because these deals are fool-proof!

Use your retirement savings or get a HELOC on your home.If you have no savings there really is no fool proof method aside from working to save the cash.

I'm confused though because you are saying we will learn how to do it but then you don't have the funding or 50% of a foolproof plan, maybe even less than 10% of a plan?
