Is there demand to fill these 4 units right now? If you aren’t 100% certain, maybe start with 1 or 2. You don’t really want to be stuck for months or even longer paying for unoccupied units. It can sometime be much harder to fill units than some folks think.
I have found that having too many options can slow down sales. Folks weigh which lot they want, which home has the right colors, floorplans, driveways etc.
If you have one that’s ready for sale, guess which option they choose?
