Putting money to make it positive cashflow

Hi,

I’m a cashflow property investor. I have been focusing acquiring cashflow positive properties (from day one) with no money down and has been successful acquiring a few. I have noticed that the properties have went up significantly therefore I feel that it is getting really difficult to find properties with positive cashflow with no money down.

Should I start putting some money out of my pocket on the deals to make the properties positive or should I still go with 100% financing even though for the first couple of years the property would have negative cashflow but internal rate of return of would be higher with 100% financing? Also, what is the maximum amount of money should I put on the deal to make it positive (I feel that 50% of the purchase price is too much as the return would not be that great)?

Thanks.

Kind regards,
Allan
