@Dan Strandberg I'm not 100% sure how it works in SK, but in Ontario when a property is located on Septic, it's often required by the lender to get a water sample for testing.

Or go directly to the tax assessors office and have them filter out a list of multis in the area, then skiptrace the owners personal information to cold call or direct mail. 

@Andrew ReidOne of the main filter systems I used when starting out is to go to a landlord friendly state.  

Slate roof (insurance company hated that, I've posted on here before), old galvanized steel or cast iron pipes that were failing piece-by-piece, old electrical with tenants complaining about tripping circuits, cracked foundations and water in the basement, and on and on. 

check that nothing is blocking water shut off valve in garage and water heater too.We check there are no extra pets

You might take over furnace filters if you plan to supply those. 

Fixed some cosmetic issues and replaced some water damaged wood on the front port.

The biggest concern is the water line is not split.
