Financing Rental Properties to Grow

[Christopher Nasca]

Hello,  I am looking to initially purchase 4 single family homes 20% down each on a 30-year mortgage, then use the net cash flow on each property to save up for another 20% to make the next purchase and so on. I'm 52, with a goal to own a minimum 50 houses. Is it reasonable or possible to keep getting 30-year mortgages for the next 10-15 years that I will not be able to pay-off in my lifetime? is there a better strategy? I plan to leave these properties and to my children when I pass. I know this much debt is not the ideal situation, but how else can I do it? Any suggestions, comments, help, etc. would be much appreciated. Thank you.
