But I do work in a finance department in the auto industry and far to many times I see young adults your age come into my office with below average credit due to bad financial decisions.

I'm sure there is a fine line between being persistent and being harassing, how do I determine that?

OH treats failure to register as a “deceptive business practice” and levies a fine, often of circa $10k.

No lists, no driving for dollars, no facebook no whatever will EVER beat a top ranking website with a fine tuned credibility score and SEO second to none!

Neighbors explained their experience to the new owners.I would hate for the new owners to get a fine and possibly affecting their ability to make their monthly note payments.Should I do something, what would you do?

If it is really a good deal look for a finance partner. 

We ultimately came up with a finance and investment strategy for the area to secure property and develop a track record. 

You also might want to get a 'ghost' number through something like Google voice to use on those signs to make it difficult for code enforcers to deliver a fine. 

The house that got me to reach out to the owner is in a fine neighborhood, split level ranch in a mid to upper class area. 

You must then occupy the property for a minimum of 12 months.If you go ahead and rent it out a month later and the previous tenant sees the listing or realizes it's been rented again, you have to pay their rent difference for the year, moving costs, and possibly a fine to the LTB.
