Numbers look good.. If your all in cost is $130K the value of the duplex needs to be above $150k.
I wouldn't spend $130k to build something that is worth say $140k.. cause you might be better off gutting an existing duplex that will take less time..
That’s a really good point! Thanks for the perspective, I’ll definitely have to consider that angle
You may want to check into the parking requirements. We see a lot of smaller lots that, even though the zoning allows multiple units, the parking requirements make it unrealistic. In other words, you may have to build multi-story to allow for parking and the shape of the lot may not allow for turning radius, etc. Good luck -
