I tried putting in a plugin freshener but the vinyl smell is competing with the freshener now.If I had to describe the smell it would be fresh cotton with a hint of burnt plastic and a dash of grade school eraser.

BAH, by grade is for housing and I did the same thing on active duty and going back to school.

Granted, those numbers are all builder grade low end specs, and I might want to add tile etc.. to increase longevity. 

R803.2.1 Identification and grade.

Carpet may be ok, and you could even use super high grade adhesive to glue down the tack strip or a few inevitable nails into the va tile.... 

In the past, when I've had to replace subflooring under showers/tub for this very same reason, I've used pressure treated or marine grade lumber/plywood.  

Hope it dies down as more come.Now, the cabinets in the kitchen and bath are in very god shape but they look a bit too "builder grade" or worn out.

I drew a little picture so it's not too confusing.In the video, it's obvious that the 4 inch line is in pretty bad shape - lots of grading issues and offsets with major healthy root growth.

In high value easy to manage markets... neutral to even cash flow or even negative cash flow on certain properties is fine... let the tenant pay off your A grade property.... what folks usually don't understand until they try to sell .. the lower end rentals have an extremely thin market especially when you own 100 of them or more and want to sell them all at once.. investors back into the numbers and most times what you think thye are worth and what they will actually fetch is two huge different numbers.

Of course they also consider repalcement value.I have worked more on hotels -- then apartments --but basic principal is same.This year I am getting into Apartments and Shopping Centers Financing.Yes --the cap rate is decided buy Lenders and Buyers --based on Supply and Demand-- Large Companies --such as Insurance Companies and Pension Funds buy --large properties and feel comfortable with 5 % Cap rate --on Hospitals , Office Buildings Leased to Large A+ credit corporation or Government -- For hotels we used 12 % cap rate --and apartments --7% to 10% --Yes -- We have to decide our own comfort level and niche --such as Grade A or C apartments --similar to some people likeIndependent Hotels and make good money as well as people who owned Comfort Suites or Holiday Inn Express --make same rate of return.
