Eventually the oil dries up and far too many investors have never experienced that and it shows 

tl;dr - I am looking at an attractive deal and wondering why, after nearly 3 months on the market, the house hasn't sold.

Are you thinking wash/dry combo or separate appliances? 

My property had a water damage because of the air conditioner pipe of the above unit.The water leaked from the ceiling, carpet all wet, so I called the construction company and the dried the wall, floor and need to get replaced the carpet.I claimed to the insurance company so they will handle it, but it looks like the insurance company don't claim to the owner of the above unit and I need to pay the deductible.What the insurance company says is the water damage is an accident, it is not the owner's fault. 

@Jessica Mowery while this is theoretically possible and perfectly legal, virtually all lenders want you to have cash "Skin in the game"  Both of the above posters are experts in this area.

@Tyler Warner we have had a severe drought this summer which is causing the ground to dry up and shrink.

In Wisconsin, it's not a cut-and-dry matter of abandonment because they are in prison. 

If you want to watch the full presentation you can do so on my company webpage, but the highlights are this:RE Lenders require collateralRE Lenders require "Skin-in-the-game"RE Lenders ALWAYS mitigate risks, the primary way they do this, require more "skin-in-the-game" from the borrowerIf you ever find a "lender" that uses a "free" email service this should be a huge red flag. 

It's unfortunate, but if the tenant doesn't have any skin in the game on utilities, it's easy for them to ignore things like running toilets and leaving lights and heat on.

I think 50k$ is low depending on the grade of the lean. if its bad then you're talking flooring issues such as tile cracking and what not and like @Eliott Elias said doing dry-wall work too.I don't want to sound like a debbie downer, but if unless you have deep pockets or you know how to do the work yourself I might look elsewhere.
