Limit of number of mortgages?

[Account Closed]

I get the concept of finding rental property, getting a mortgage, and renting it out obtaining positive cash flow while soaking up the equity. However, is there a limit to the number of mortgages one can receive? Will lenders start to decline my request for a mortgage due to me already having too many on my credit? If the answer is yes, then how do I overcome this hurdle to create a snowball effect (keep obtaining financing over and over for renting out more properties)?
