Dean said that is too many.I see that not only as a good thing but a GREAT thing. 1 - it's good for the community. 2- It will force the bad landlords that give the business a bad name hopefully out.

How will this impact your potential buyers? 

If push comes to shove you can force his hand and he will have to allow for the repairs.For the record his parking on the yard is probably against local codes (that's a very common code in all areas), and you could attempt to hold him liable for the repair cost associated with his "damage" to the lateral.

I am unable to get a loan as we were forced to foreclose on our first condo (bought in 2004 and foreclosed in 2012 after a job relocation).  

Plant a few pansies and your done.Buyers are going to be in full force this spring and you might create a bidding war! 

So, if there is no way to force appreciation, how are you planning on making money with this?  

It's essentially a forced savings plan. 

I had also prepared to offer the occupant cash after moving out rather than have to go through the eviction process to create a sort of win-win, rather than a loose-loose (where the angry occupant is forced out and destroys the house along the way).  

Its more impact resistant, cheaper, less time involved in install and can easily be replaced.  

I include the following: Tenant understands that any judgment or collection activity concerning Tenant’s default on rent payment could adversely impact Tenant’s credit rating.As someone else recommended, be sure to familiarize yourself with your state's landlord/tenant laws.
