Others deliberately hide their success so the exaggerators don't pester them!

The first house that I bought was 17 years old, 3 br, 1.5 bath, brick ranch house with hardwood floors, Andersen windows, ceramic tile baths, gas heat and a brand new roof. 

I don't think you are going to be able to get insurance for two separate living units in a single-family when they are both illegal and likely do not have the correct egress windows (basement) for fire safety which could subject you to huge liability if something happens to either party.

Not interested in installing new flooring or new windows.

No window air conditioners or freezers are ever included in the lease. 

@Jay Hinrichs has posted on that in the past.Many people like to try and hide their identity because of the spotlight effect which refers to how people often overestimate how much others notice (or care about) them, effectively inflating their own importance in society. 

It's an A-framed garage with shingles roof, gutters, windows, and a 32" exterior door (in addition to a 16' operating face door). 

Some gurus tell practicioners of sub-to to hide transaction from the lender by saying the lender doesn't care as long as the payments are being made.

It is much more helpful than pictures to see you aren't hiding anything.   

I see investors all over the country making 30%+ cash-on-cash return, BUT there are also people throwing money out of the window.
