Another common one is that if you declare that you will be an owner occupant of a property to live there for a year that you don't sell the property before that. Banks favor accepting owner occupied offers. They are trying to discourage buyers from lying to them about this.
Some are added previously that continue with the property, such as a life/lease or a restriction to build certain types of businesses on the property.
Most Deed Restrictions nowadays are put there by HOAs who limit you on the color you paint the exterior or the type of roof you use.

It sounds like you are trying to buy without the guidance of a Realtor.
Good luck and may God bless
