In my area of California, properties that have been rezoned to fewer units are like gold mines. Let me clarify, we have multiple properties that are zoned for 2 units or less, but ours are 3 or 4 units. Now I'll list the bonuses:
1. Extra doors, means extra money. We definitely earn 2x to 1.5x what we would be earning with the extra units.
2. Tenants don't care as long as it's nice. They will pay market for the unit, not the zoning issues.
3. DO NOT TELL THE CITY OR TRY TO RE ZONE. My city in particular is not about to allow rezoning. As far as the city is concerned, we have "legal non conforming properties". They are legal, but they cannot be recreated as they are today as they don't comply with zoning. If we were to tell them, the city would make us remove a unit or two.
4. Only bummer is that you can't recreate it in case something were to happen. Have a client who is always concerned about whether not you could recreate the property because he has had a property burn down. Ultimately, his bigger concern is making sure that he could generate the same kind of income. That's somewhat of a toss up sometimes, but they're still my favorite properties.
Consider it a slam dunk!!! Congratulations!!!
