Besides the serious infractions, the minor ones can cause you to lose money in fines and the loss of the ability to collect on your loan, fair collections practices alone can deny you the ability to collect in addition to fines.

YOU can't do anything. except write up a unauthorized tenant living in unit as lease infraction. that will either be remedied by adding the new person on or booting everyone in the unit.The police won't force the new roommate out.Check landlord tenant laws for your state and comply with that.As long as current tenant gave access to the unit, it's the tenants problem not yours unless you press the unauthorized tenant issue.. as far as my experiences have shown. 

This is another big infraction with SEC. 

Has anyone invested in fractional equity investments and what was your experience?

If not and you have an infraction they are free to set fines as they see fit and expect enforcement to be uneven.

Any infractions will be addressed, up to & including eviction.

It's easy to get caught up in fractions of a percentage difference between various cities.

I personally no longer buy properties directly, but invest small amounts ($5-10K) in fractional real estate syndications.

Tenants with legal infractions in their past often find barriers to housing and employment.

Just leave a note saying you entered to fix or service what was needed..if they won't let you in I guess you call water dept and have water shut off at the curb if it's water related.. call gas and have gas shut off at outside of bldg if it's gas related, notify police your building is unsecured and you have attempted to secure but have been barred access and need escort.. and you file eviction emergency action for cause I always have phone camera ready..the he said , she said on this will be a ongoing situation.. get them both out.. mutual lease termination if possible.. just document noise infractions,, and damages,, police calls are not infraction if they call themselves.. if neighbor call police get copy of report.. if you call its a unsubstantiated report/ shows bias and cant' be used as reason for eviction. better if tenant or neighbor calls.One way or the other they will get out.. damages will happen and better to safe guard yourself then to get between 2 crazy people.. the cops out there will tell you the most violent unpredictable calls are domestics.. and people get hurt, killed,, don't let it be you.
