BEFORE my safety net of 10% income, it looks like I should get a ROI of 15% which I really liked but now after the safety net it is closer to 3% and no longer looks like a good deal.

This would make you liable for fire safety, since you can't (at least in Texas) have a double keyed-deadbolt on an exit door. 

Where this also helps compared with mobile homes is most of our homes need to be 15' apart for fire safety, whereas I would imagine these could have a 0' offset.  

Seller financing usually comes into play because of three situations1- Property is not financable (construction defect, hazard, uninsurable, needs extensive rehab, etc.)                                                  

This issue has effected me widely and created a major safety concern if I want to drive for dollars  and look for properties . 

If there are safety issues or any defective systems, it is likely that they will not lend to you to BUY the distressed property TO renovate.

It would be a wonderful world if everyone could afford every safety device and had time to research them, but the truth is that sometimes you have to wait until time and money permit you to set up things for a large company. 

People feel safety in doing what everyone else is.I talk to everyone about it, I get negativity, but I don't take it personally.

A flat roof can be just as durable as a normal roof sloped if it is installed correctly and I don't see how it can be more of a fire hazard since it is wood like the rest of the roof.  

Clear title means that there no other claims upon the title interests of record owners, such as mortgages, tax liens, judgments and defects in the recorded chain of ownership.It make look like a little thing to you but may mean your title includes lots of attached baggage, like undisclosed debts, liens, lawsuits and even brownfield issues (hazardous substances).I hated title research when I started many years ago but came to learn how to make money from the mistakes and oversights  by others.
