I agree Jason, I use the 30 day rule and then lower the price unless you have a seasonal market where you are. 

I believe the 90 day rule starts from the date the deed was recorded (Jan 2018).

It may be in your HOA rules or docs what percentage vote is needed to make a new rule or change an old one. 

I will agree as a general rule of thumb.

You'll get to take the 121 primary residence exemption when you sell with some restrictions.1.

(Supreme Court ruling) They are in business to make money.

Signage restrictions would be a good question (color, size, etc). 

The tenant attorney and tenant rep broker of course will try to do the opposite of what the landlord wants in ultimate guaranty security of lease, annual rental increases, and long term primary lease term.If you left it up to a tenant they would try 3 year primary lease, blocked rent increases so not annual, sales clause if not at certain level they can terminate or reduce rent, co-tenant anchor clauses, crazy broad restrictive uses for other units in the center, no personal guarantee, no disclosure of personal or business financials per the lease, set up a single entity remote LLC so they can bankrupt it for one location if things go bad, put a ROFR clause in the lease, incapacity clause where if tenant gets sick or hurt they can cancel lease, construction road widening clause where tenant can pay reduced rent while access is reduced to the center, unreasonable CAM cap clauses, etc.I can go on and on with the crap I have seen in leases for my clients buying retail centers where I am the broker.

The one tenant / one check rule keeps it clean on your end.

With HELOCs, each bank can (and do) make their own rules.
