So I am thinking if I can put on a used mobile/manufactured home on the lot for rental because it should be much cheaper.

People say it's slower to scale but I've been able to scale fairly well because of how easy they are to manage.

So an asset with a higher risk profile should receive a higher potential return.Given that multifamily is less risky than SFH (the scale of MFH evens out returns) you would expect SFH homes to require a higher ROI.Is that what you're seeing, or are you saying the opposite?

Even then, several businesses will be seeing over seas demand dry up.The only things we know for sure right now are that nothing like this has never happened before, our institutions (financial, business, political) were not prepared for anything on this scale, a lot of investors and consumers are carrying high levels of debt, and the short and long term implications of our crisis management efforts on the economy are not understood yet.Hopefully it works out and everything goes totally back to normal in a month as if nothing ever happened.

Any suggestions for finding passive investors on a small scale?

As you scale up, leverage software to help you automate and grow. 

I am also exploring investment opportunities (SFH, small MFH) in both Chattanooga and Huntsville.Healthcare and logistics/manufacturing are some anchor industries.  

I want to maximize my time by focusing on developing the necessary skills to scale as fast as possible (ex. learning, bringing in income, better understanding the market I'm in, etc.)I am interested primarily in residential real estate (long-term hold multifamilies) and was wondering if you knew of any top firms specializing in this area of real estate?

Over 6% of all homes in the US are manufactured homes.
