This is a win, and just like anything else in life random things happen and you have to deal with them. 

I am interested in having a long term investment, I may be breaking even or have a slight loss depending on the rent but I consider having an asset paid off a win.

Win-win.

If they give you a lower number than you are willing to pay then it's a win for you!

Know your area extremely well from a rental law/registration situation, know the players (PMs, contractors, inspectors, suppliers, etc), attend meetups or start one if there is not one in your area. 

You said it could break even, that’s a win. 

It's easier to use these terms off-market but I use them on market all the time as well unless it's very competitive and an inspection or walk-through needs to be done prior to going into contract to waive the inspection to win. 

I would recommend looking up local real estate meet ups in your area and attending as many as you can - this will be a great way to network with lots of players in the industry including real estate agents, investors, wholesalers, lenders, etc

Sounds like a win win win! 

My advice would be to create relationships and go for a win-win approach.
