Amanda,
Your goal of $10,000/month in passive income is very achievable. As you start to build your portfolio, consider the risks (controlled and uncontrolled factors) that will cause variances in achieving this goal. You really want $10,000 per month every month not $12k, 9k, 10K, 8K, 10K....
The most important factors you can control include 1) whether the property cash-flows, 2) how you finance the purchase, 3) the type of property (SF vs MF), 4) the type of tenant and 5) whether you accept deferred maintenance, 6) the your ability to offer (or hire someone who offers) world-class property management service to the tenants (and you as the owner).
Everyone spends a lot of time on the first 2 items and possibly number 3, but few think through the last 3 well enough. This is a long-term investment as such we must think about years 10-30 as much as we think about year 1. If one invests in a market with a declining population, one must expect minimal rent and value appreciation if not depreciation over time. If one invests in a 'hot' market with proven wild swings in growth/decline, one must expect wide variance in their month-to-month performance over the years. Neither of these are risks you should accept for a long-term buy-and-hold investment. The securities market offers plenty of opportunities for this type of investing.
Landlord laws are what they are. If you do this long enough and have enough homes, you will have an eviction. If it takes 6 weeks rather than 2, that certainly affects your vacancy rate. However, minimizing turnovers will have a much bigger impact. Providing great homes and great service to great people is the best way to get consistent returns. If tenants are proud to live in your house and you are responsive when things happen, they will not want to leave voluntarily or otherwise. This will not only make your returns more consistent, but also more profitable.
I wish you the best of luck as you get started!
