@Alex Saepharn I agree with @Clayton Mobley as there is a vast difference between returns on paper and actual returns. I would focus on investing in less properties but in the best neighborhood possible where the cash flow is large enough to make you sleep at night.
I'd also purchase with your exit strategy in mind. If you focus on lower end properties then you'll only be able to sell to other investors who focus on the returns of the asset. By focusing on homeowner neighborhoods you'll be able to sell the property for top dollar to an emotional owner occupant upon tenant turnover after upgrading the bathrooms and kitchen. Even if you chose not to at least you have the option and in real estate make it a priority to have as many options as possible.
The downside to that method is you could only sell each property one at a time since it is based on when the tenant leaves. This means you wouldn't be able to sell the entire portfolio and 1031 into an apartment building etc.
Happy Investing!
