Either you or a representative you trust with out exception must perform all the necessary due diligence just as you would for a property down the street from you.Turnkey companies want to maximize profit by doing as little work as possible using the cheapest materials.I would have a professional inspector check everything with a fine tooth comb,especially the roof,plumbing,electrical,and HVAC systems.Also make sure you get a repair warranty for when things go to hell in two years or less(and they will).I honestly don't trust any property I don't rebuild myself with my trusted contractor and quality materials that will last at least a decade or more

Here is a part of the letter, I sent to the seller:The home inspection was completed on September 29th (please see attached) and the following issues were pointed out: 1.The wooden floor frame in the middle unit is deteriorating due to either prior water leak in the bathroom or due to moisture infiltration through the walls and foundation.2.There is evidence of significant settlement under the middle unit bathroom and north closet.3.The settlement of the floor and walls has also resulted in settlement of the roof frame above this area, ceiling shows cracks.4.There is an obvious depression on the roof – water is ponding on the roof above the middle unit, which adds excessive weight on the roof and potential for leaks.5.Asbestos containing material has been found.6.The current bedroom heat installations in the north and south units pose a safety hazard from carbon monoxide, fire and oxygen depletion.7.An electrician performing upgrades did not use ‘arc fault breakers’ in the north and south unit breaker panels, which is required by the national electrical code.8.Upgrades to the electrical system, promised by a real estate agent, have not been completed yet.

They've rewired the electrical and installed new smoke and fire detectors.  

You end up buying, new HVAC, paint, drywall (maybe), electrical fixtures, kitchen cabinets (maybe), flooring, and appliances.The law actually protects the person that follows it.

I lease a 2015 hybrid gas/electric plug-in (Ford C-Max) for $234/month.  

The upside if I end up keeping this property is it should be maintenance free for years with new roof, furnace, hot water tank, electrical completely re run, and plumbing.

What is your trade, I would say niche, wood work, electrical etc?

Also if you talk to them they have some plumbing and electrical guys that they know that can even work with you if you want or give you rough estimates.

I'm a contractor here in Indy specializing in plumbing, electrical, tile floors, custom tile walk in showers however I offer full service minus HVAC. 

Contractors licensed for specific skill sets, such as electric or framing, are sometimes used as subcontractors by a general contractor, and will sometimes be used by you for specific sets of small repairs.
