At some point a question was raised on condo converting these things, as based on the description, there seemed to be no reason why they couldn't be broken up.

You'll be paying for everything from cable TV to broken dishes.

The $13,000 includes:Replacing one entire gable, repairing another gable, tearing out all bathroom tile and old vanities, new flooring (vinyl plank), 4 new ceiling fans, 2 new toilets, 2 new bathroom vanities with new countertops, sinks and faucets, new kitchen counter with new kitchen sink and faucet, paint on all surfaces inside and out (except brick), new doors, new hinges, new cabinet hardware, new bathtub surround, minor carpentry repairs, all new light fixtures, all new switches and outlets throughout, some minor electrician work, minor plumbing work, various minor drywall repairs, gutter repairs, painted concrete porch, new pillar for front porch, doorway thresholds, all new blinds, replacement of a broken window pane, all the appliances, and all the labor.

It is generally broken down as maintenance, CapEx, taxes, insurance, property management, and vacancy.Depending on your local taxes, vacancy, etc, you might find yourself above or below the 50% rule.As far as splitting out $250 per door, this would depend on the individual property.

I've done a fair share of research but I could use the collective experience of BP.They guy is paying far under market rent, he has 10 broken lawn mowers in the back yard, one disabled car in the front yard, has let the bathroom floor rot, and the siding partially fall off....

I once had to cap off a broken water line where the valve had broken off. 

To top thing off, within a week of the repairs being done, the house had been broken into again, the new pipes and water heater stolen.

there is one who did a pod cast on BP and has gotten a lot of traction.. not that they are or are not scam artist but they are recommending buying 30 to 40k turn keys IE homes that all in cost 30 to 40k.. and we all know that pretty much in ANY major metro those are squarely in the hood.. war zones etc etc.. lots of hearts are going to be broken with that company in Indy... it will take some time but it will happen

I have done work with tenants in place that is cosmetic, broken up floors, bathroom tiling and such. 

Cosmetically I would change the carpet upstairs, fix some broken windows, and some paint.
