Unable to buy a residential rental lot

I buy it and am taken to the rental property where I can see the lot information in the properties tab, but as soon as I leave the lot the property no longer shows up but the money is still gone and I can't repurchase it as it says the lot is owned. But by all accounts I don't seem to own it.

EDIT: It seems to trigger when I try to move my Sim, who owns the lot, into one of the rental units.

Up until that point it's fine, they're shown as owning the lot, but once I go to rent one of the units I no longer own the lot.

EDIT 2: If I move them back out, they own the property again. But they can't seem to own it and live on the lot at the same time.

(probably last) EDIT: Okay, I was able to fix thing by buying the lot as a residential lot and then converting it to a rental lot and reassigning all the units.
