Quote from @Michael Smythe: @Don Konipol mostly good stuff!

They must provide quality service, or their clients won't want to pay the price.

A few things that newer investors should note:- it took 13 years to get there, you have to be patient- rents are high at about $1,750, so probably a quality neighborhood- looks like that is after vacancies, probably low turnover?

High end vs mid range?

Its proximity to campus, turnkey condition, and rental history make it particularly appealing to investors seeking high cash flow and low vacancy risks.

Sounds like you need to have a relationship with a couple of good contractors, 40k for vinyl siding sounds high, what was the material cost.  

Could be a business decision based on keeping long-term high quality tenants rather than risk the costs on turnover.
