Owner financing, from a newbie here.

[Phillip Synenberg]

My father bought a single wide trailer back in 2008, lived there for 4 years and decided to move across town, from Grovetown to Augusta Georgia. 

In doing so, he advertised his trailer for rent and decided ultimately that he didn't want to be a landlord forever and met a suitable tenant that he was willing to take $2,500 down and let her make payments on the trailer until it is paid for (about 8 more years). At which point he would sign the title over. For what it's worth, he cash flows about $200 monthly from it. 

I know, it's not ideal, and all of this took place before I had an interest in RE, much less ever learned about BP.

He had a contract written up and notarized stating that he will keep his insurance on the trailer, but should there be any issues she is ultimately responsible for the $500 deductible and should something go awry, and she cannot afford it, it's considered defaulted and she must move.

He called me tonight in kind of a panic that she had called and said that the roof is leaking, and she has no money for a deductible. She had the gutters cleaned "when she first noticed it" so who knows how long it has been going on. 

He is going to look at it tomorrow and make sure its not something as simple as a loose shingle, but my question for you all is as follows:

Although shes "purchasing" the home. He is still ultimately responsible for the fix according to Georgia landlord laws, although they have a notarized agreement stating otherwise, correct?

Should it be a bigger issue and the deductible need paid, and she cannot, is this legal terms for defaulting? 

Shes been a pretty okay tenant otherwise for the better part of 3 year, ie; her rent was late twice over said time period. Can he just make an addendum to the end of the contracting stating about an extra payment to cover the costs?

 How would you handle this situation? 

What can we do to ensure we stand on the legal side of the law?

Thanks in advance for your advice/input. 

Magically yours,
