I am currently in a project making my fathers house ready to sell , 2000 sq ft house , 14 replacement windows , paint . 10 pre hung 6 panel doors , some framing lumber , 10 sheets of drywall some plumbing supplies and misc things and I am in close to $10K . ( NO LABOR MATERIALS ONLY )I havent done Kitchen , flooring , 2 bathrooms , or exterior needs paint and touch ups . .  

What if this rental rests on an Indian burial ground and the ghosts come out and slay my tenants...then for good measure poke holes in my plumbing while they're at it!"

There's no plumbing or HVAC up there.

I also own a plumbing and a construction company, so if you have any questions please fill to ask.  

This can tell me a lot about the age of the plumbing, roof, HVAC, etc before actually walking it. 

Plumbing looks good as well.

But we're definitely see a lot more folks come into the market domestically whereas before it was much more international. 

Buying this kind of real estate avoids going into CAP EX improvements too much, as most plumbing and electrical is still good and close to todays codes, and you are not dealing with plaster walls.

There will be no power for a day or two depending on your licensed contractor.Plank or batten box house is same as a log house (can't conceal electric or plumbing well), I would make them safer.  

For a mid-efficiency gas furnace, expect costs between $2,500 and $6,000, while high-efficiency models can range from $3,500 to $10,000.Plumbing and Asbestos: Plumbing costs can vary widely, from minor repairs in the hundreds to extensive replacements running into thousands.
