I have three options:I can sell to my tenant - most of my tenants are interested in home ownership, eventually.I can sell to an investor - I only rent M2M so I can offer a home that produces income or can be vacant in 30 days notice.I can sell to the open market - most of what I own is SFH, so I have a broad market to advertise my house...I can also sell my home below market (because my purchase price is right) to get out quickly if I need to and still make a considerable profit.Multiple properties may incur higher PROBABILITY of a bad thing happening, but it will yield you a higher PERCENTAGE of return on your investment IF you stick to your investment rules.My largest "contrary to the popular belief" is that I buy not to generate large amounts of cash flow (although each property does @Justin Fox brings up a good point that it isn't just what you have left after you pay PITI), but to keep my equity safe and building as I own and maintain the property. 

Danny, did you get the tiny home built out yet?

I see tiny houses in your profile so maybe give a few details about what you are looking for.

I have been pre-approved several times and can produce that type of letter, but cannot produce a bank account full of cash letter to go along with my cash offer.

Everyone knows a fight in court only produces the attorneys as the winners and is actually very costly to the parties paying the bills.

As a example  mulyi unit will produce higher more consistent returns than a SFH. 

Instead of mobile home communities, is there a way to develop a Tiny Home community? 

For instance If I know a investor who is looking for funds, backed by income producing property.

Furthermore, not only is the next door neighbor very close to the second bedroom window (bushes could help), but also the backyard is tiny.

I wouldn't sell any piece of real estate unless I have already identify a new asset that produces as much more more income and have potential to create new equity or I desperately needed the capital to pay for a tragedy.
