Plumbing all that to the house is a couple grand more before rough-in.My property is in a very rural area right next to a popular ski resort plus it is elevated on a ridgeline.

They mention termites, signs of water proofing in basement (we didn't waterproof), pluming and electrical repairs not disclosed, not disclosing a new roof, and they were suing for 150K on a 165K house...The truth of it is we didn't know of any leaks in the plumbing or the roof.

the challenges with flips  is that there are so many angles to try and cover / consider that it is somewhat like spokes on a wheel… even if you just take it system by system… roof, plumbing, AC, foundation, subfloors, electrical, appliances, septic, materials expenses, holding costs, taxes, etc.  

If you had to come out of pocket for a water heater for $1,000 in a given month, or a $300 plumbing call, or an AC call, can you comfortably do that type of thing with your finances?  

The major factors like the roof, furnace, plumbing, electrical upgrades, and foundation repairs are all examples of costly expenses you'll want to inspect before closing the deal.

Some common items to note: roof, electrical and plumbing, window updates.

So the house wound up needing the drywall, kitchen, bathroom, roof to the garage, Plumbing, Gas and other stuff done. 

Thanks for responding.I’m comfortable with residential electrical, plumbing and framing.

If you need plumbing replaced does your plumber charge you based on a % of rent?
