I was there last week doing some work and I did notice some dark colored dog hair along with the yellow lab hair on the white tile. 

However, the annual rate of increase halved in the last year, as shown in the first chart.

It ended up being just a hair below our purchase price.  

Does anyone supply their rentals with shower stall drain hair catchers (such as the OXO brands)?

Denver was always my first consideration but the market there is off the charts right now.

@Ben Leybovich My hair is turning gray, hence the updated photo. 

the only bummer is I can't get any bank there to loan me spec money so we had to do it out of pocket.. if I had bank money my COC returns would be off the charts.. regardless we pushed on.. and now we have almost 10 new constructions built and sold.. 6 rehabs we did in the last year all bought rehabbed and sold with very nice margins..

It sounds like cashflow but I can't understand what sort of cashflow you're going to be pulling in by bringing on a partner at this stage...you'll be splitting hairs.  

If your one lender bets wrong on the direction of rates or underwrites a large non-performing portfolio they could get a hair and start doing weird things.  

If your bad almost-tenant had a poodle breed and the former tenant had a breed on the bad end of the allergic scale, it's possible that what she said about being affected by the previous dog's hair has an inkling of truth.Regardless, I would not have wanted to rent to her.
