They'll flunk you on all sorts of silly things and simultaneously turn a blind eye to significant infractions at your next door neighbor's house because he's a local and in tight with the committee. 

I read 80% of license pulling infractions involved "Dual Agency".

Each of these cases support a discount applied to fractional interest.It may be difficult to find an appraiser experienced in fractional interest in your market but if you make enough phone calls you will find one.

Still screen as you would anyone else though and communicate with the housing authority so you can report any infractions if needed. 

As long as you don't have glaring safety infractions; missing hand rails, broken windows, no CO2 detector etc. you will be fine.

Detail every infraction of the lease over his tenancy.

From my reading you are only prohibited from evicting due to non payment but other lease infractions are allowed.

An investor who derives all or most of their income from activities is viewed by the amount of income in relation to their net worth and such activities being customary for someone at that level.RE investors who don't address the "being in the business of" aspect really opens themselves up to other issues, business license infractions, insurance issues, local and state tax matters and perhaps IRS issues as well as professional license issues.Regulators with the dept of finance here in Mo. take the position of "if it quacks like a duck and walks like a duck, it's a duck".

I have no idea as each violation will likely be viewed on its own merits or infraction of a regulation or law.
