Potential investment property has below market tenants

[Chris O.]

Looking at a 1960's Duplex on the island - it's been updated inside so no need to renovate. Also won't be living in either unit - I've got one side vacated but the other has tenants that are $400-$500 below market rate. Deal only makes sense at market rates on both sides. Anyone know of any options or is this a dead deal with the new rules passed last year protecting against rate increases
