But we'll have gotten our foot in the door with infinite cash flow for our part.

Further, I bet he had 100% financing and is using the rent to repay the debt, which at $0 invested for him is an infinite return when the debt is paid off in 5 years.  

It is not clear if you even plan to capitalize this transaction, which if you do not, you have an infinite return with no cost basis.

This is someone looking to get into real estate investing that has good credit (can qualify for their own 5 mortgages), but no cash...and most likely no time to be an investor.5 - Repeat steps #2 & 3 with them...with you providing the "Entrance Strategy" (the cash IN), and you new Credit Partner providing the "Exit Strategy" (the refinancing to get the cash out to re-use)6 - Split the cash flow and any future profits if house is sold.7 - Repeat step #4 - 6 as many times as you can find Credit Partners.8 - After the last refi, whenever that would be, you refi you (original) cash out, never really ever "spending it"...just using/moving it strategically.The answer to your original question of "How many homes can I purchase", is an infinite amount with limits based on available homes and available Credit Partners.Joe VilleneuveREcapSystemA2REIC 

@David Oxandale, with "0 down", of course ANY positive return can be classed as "infinite" CoC!

Hey, I can buy the six pack :groovy: Your "infinite wisodom" will be more then appreciated!

Less than one year all money out and CoC return infinite.  

I'm learning that knowledge about real estate is infinite and no one man can know it all or do it all. 

question: how can i make an infinite return with this property in 2-5 years ?

It takes a considerable amount of time to find them though, as competition from other investors is very high at the moment.5)  I typically try to invest with infinite return.
