It'll be metallic accent walls and pickled shiplap all over again.We'll have more people wholly ignorant of the nature of DWV plumbing who will insist on moving toilets from one side of the bathroom to another because "the light would be so much better" and so would "the harmonious energy of the room."

I like what @Jaron Walling said above.

Since cabinets, flooring, electrical, plumbing, etc. have to be upgraded anyways, is there a financial payoff for turning the units into 1 bedrooms - e.g. moving the kitchen wall into a bedroom, creating a design that looks and functions better?

Don’t waste a mortgage on a single family.

Nothing gets installed on top of the planking cause they need to expand and retract with temperature changes, plus you need at least 1/4" space between the flooring  plank and baseboards or walls to allow for movement

She also has low credit score of 500 and a collection for medical bill.I totally understand the desire to get the unit filled, it's painful to think about the money wasted when your unit sits vacant.

@Paul VailSomething else to be concerned about Meth houses is; where the occupants were dumping their waste chemicals.

As we removed the 'walls' to the studs the original wall to the house was uneven. 

If you have a nice budget (3k or more in a decent sized market or don't waste your time), definitely get a website and do PPC.
