Dry wells are required to "store" the rain water on your lot from all impervious surfaces for 24 hours, including the driveway! 

A lease longer than 3 years also violates the due on sale but is less likely to surface to the lender's knowledge, but could.Obviously your questions reflect your level of knowledge, not being condescending just sounds like you're really new.

As Nick said, there's more to the deal than what's on the surface.

Previously to this I had replaced carpet with ceramic tile (already a couple of chips through the surface layer), Pergo (still looks like brand new after 3 years but is not waterproof like LVT is) and when I bought my first rental, carpet, which was ruined after 3 years. 

@Matt Holmer, I'm not so hot with numbers either, but on the surface it looks like the Seller would be receiving an average of around 4.5% return per year, with the final balance of $112k being in their pocket at the 10 year mark. 

Once the surface is filled up ... level it off with top soil on top if you like.

I agree - $2k sounds way too high unless they painted every surface of a very large area.

Tenants can paint a room in  2 or 3 hours all 6 surfaces 

I'm only really scratching the surface.

On the surface, there appears to opportunity in Saint John - a larger inventory at better prices - when compared to here in Fredericton ... even when you consider in vacancy rates, rent levels, etc.My first reaction to such a discrepancy is: "There must be something about Saint John, or specifically, Uptown Saint John, I do not know/understand that is responsible for the discrepancy in inventory and prices between there and Fredericton (and Moncton)."
