@Eric Meyer And to answer your question about returns on any particular property, I prefer to think about returns as a percentage of my investment. So, instead of looking for a flat dollar amount, I look for a 12% COC return. Unfortunately, it's hard to compare returns with other investors because everyone uses slightly different numbers in their analyses. A property that provides a 12% return to one investor might be a 10% return to another. Or a 14% return. It's hard to get good apples-to-apples comparisons.
So, for your question about whether $200/door is reasonable, it's hard to know without more information. Are you buying $40K properties or $120K properties? Are you considering SFHs or just duplexes? You might want to calculate your return as a percentage of your investment to better compare different properties - $200/door could be a great deal or it could be a bust but if it's a 15% return on my calculator, that would be pretty sweet. But you need to know that I prefer SFHs, I buy with 30 yr mortgages, I'm conservative in calculating my expenses and I aim for properties between 70-100K in B-ish neighborhoods. Oh, and I generally buy them off the MLS or from a turnkey provider because I'm an out-of-state investor. You have a huge advantage being local and can likely get better deals.
Forgive me if I've just told you a lot of stuff you already know. It's just that $200/door is a hard thing to compare without some context.
