How many mortgages can I can I have?

[Andrew Adam]

I live in Sioux Falls, SD and am not sure how to find out how many mortgages I can have here in my name. I heard on on early podcast that it was 8, but then I also heard that it was ten. Does it vary by state?

 I have one mortgage on my duplex, and in 6 months plan on getting another for our single family home, then over the years getting another 5-20 rentals. Long term what should my plan be as far as how many mortgages I can carry before I have to start doing 100% down or contract for deed?
