This is driving down the rental apartment/flat market in the urban areas where I have properties too and effecting my cash flow.

On average, the annual rental increase has been 0.87% (since 2009) and is going to be flat for the next 5 years.Is this typical for a NNN lease (i.e. do the renewal negotiations skew so far in favor of the tenant that they can get the landlord to pay for major repairs etc. and the annual rent increase is quite small)?

By being about 75% (2019) to 88% (last quarterly call report to stock owners) refi, where you can just bake the unusually high junk fees into the loan balance (unlike purchase mortgages), that's exactly where they are at in the market.

I traced it to her toilet, which had been running for at least 3 days based on the water rushing down the drain pipe in basement (which at the time I thought was rain draining from the flat roof).

You should be able to buy a 3 flat for that all day long all your numbers will be better. 

Ultimately, He would like to stay and live in the “granny flat” or Ohana unit and be a “house manager” for the property.Are there any creative suggestions people might have in how I can help him and seize on an opportunity?

As far as I know, there are flat fees, and percentage fees for them.

I'm the Chicago suburbs, but a downtown 3-flat (Chicago is weird and calls 3 units a 3flat instead of a triplex) in an A+ neighborhood like Lincoln Park or Wrigleyville will never cashflowMy wife and I even looked at a couple that could be used as an owner-occupant and the rent from the other units don't offset the mortgage.

In our market the property prices rose significantly in 2020, but rents were flat. 

@Aj Parikh but shouldn’t I use this time to maybe reposition the portfolio toward newer and higher growth neighborhoods while the market is hot given the flat rent growth and other tenant quality aspects?
