I hope you are staying safe in this difficult time. 

its highly risky for most mom and pops to sell on sub to.. and its simply not a way for those without substantial wherewithal to buy property and keep the seller safe..

Other parks our size have about the same rent but have water included or basic cable, have rec centers or nice playground / pools, have multiple works on site.

It always better to be safe than sorry, but the building dept will let you know what the best course is.

I like to look for locations that are good, and that I’d feel safe and comfortable living in if I was a single woman with a couple of kids.

So, in the end I would caution anyone who wants to try it to hire a real good counsel, a Dodd Frank/Safe Act/TLA and CFPB versed attorney,  and thread the waters accordingly.

We are in a safe community, so tenants can choose to leave the door unlocked or hide a key under the mat.

You can put a mortgage into a "trust: without triggering a due on sale but again contacting your bank/lender is the best route to avoid any issues.Some banks/lenders or servicing companies change guidelines and even a trust may require other paperwork but the attorney usually facilitates that to be safe.  

Hopefully, everyone stays safe and the firefighters can get a handle on it soon.

There really isn't a safe, secure way for someone to protect their interests.
