In my experience, most agent will add in language that clarifies things, UNLESS their supervising broker restricts them from doing so.It never hurts to ask, because you just might get what you ask for.

So some banks put extra restrictions on investment property loans.....and some just don't do them at all! 

But there are some restrictions on getting that extra 10% off.

One of the other restrictions is that you can not provide labor, like in the case of doing the work on a flip property yourself. 

I would assume this language is in your docs, otherwise the HOA would not be allowed to restrict it ... obviously.

The exact application can get complicated and there are many exceptions (e.g. restrictive covenants in employment contexts have special rules).

Even the US has imposed restrictions on cash transaction in some locals. 

@Kai Van Leuven Best place to start is talk to the city / county about zoning restrictions.

I think the only restriction on this would be your ability to actually execute the lease.

Basically, there may be limitations or restrictions that result when you separate property ownership from property management.
