Sitting down to make business plan. A question about multiple mortgages.

[Jeff G.]

So I am sitting down to iron out my business plan. Spending time on BP it seems that many people who have 15,20,50 houses hold mortgages on most of them. My wife and I are conservative by nature so the thought of 15-20 mortgages is scary to us. My thought was that in year three when I should have 4-5 duplexes to pay one off prior to moving on then acquire a few more properties then again pay off a mortgage or two. As a 32 year old am I ever going to be able to reach 20-30 properties doing this? The market I will be investing in the properties are only 40-60k for duplexes. With monthly rent per property of $1100-1200 and taxes on average of $1200. Input is appreciated. Jeff
