I am too busy to hear about the latest unit that got broken into and stripped.. or the latest drama of tenant who cant or wont pay either their total rent or their portion of the rent after the section 8 payment. and then the constant turn over and cost associated with turnover.. the Investors buying these are not C and D class folks like the tenants that are going to occupy their props so they really have very little clue about how those folks live their life and on the razor sharp edge they are financially.

I wont answer for  Brian the expert..
