If I were buying a home subject-to and giving the seller some money for their equity, how is the seller protected if I get hit by a bus after recording the deed.

I'm not declining you because of race, sex, religion, sexual orientation etc.....

Because he was rude, talked over my employee, and didn’t listen to anything we said.I will never, for any amount of money, allow my team to take personal abuse.

There is usually no property tax but a Mobile Home is usually Registered with the state and the owner must pay an annual registration fee.Mobile homes are not built as well as stick built homes so do not stand up to tenant abuse as well as stick built.I do not understand some of the monthly numbers you presented, can you calrify

It's difficult because it's next to a bus stop with no fence.

Unfortunately, there is a lot of abuse of THTs.  

After 2 months of living there (I lived above one of the units rented) I would witness the tenant literally screaming, cursing, and being verbally abusive to her two sons (4 years old and 7 years old) - loud noises all day and night, etc.

near a bus stop?

The work turnkey has been used and abused but simply stated all major components have been replaced, the home has been renovated to 2020 standards esthetically and to code, and will attract a highly qualified tenant.

Rental deposits are really the tenant's money that is held by the landlord against damages you may suffer (when the tenant vacates) due to damage due to tenant abuse, unpaid rent, and even for a broken lease.
