I'm getting into rental arbitrage, and I'd like to have an addendum I can offer to landlords to be added to their existing lease. The idea is to cross out the "No subletting" clause from the lease and replace it with "See addendum." The addendum should at least specify that I'm allowed to do short-term sublets through AirBnb, etc. Perhaps there are also other clauses it would be helpful to include for my arbitrage business.
Does anyone have an addendum for this purpose that they'd be willing to share? Or even a set of points that should definitely be covered somehow in an addendum? I'm a newbie and would certainly be grateful.
