Can't get house in Nulb

Getting a bug (?) with the conversation with Preston, the Mona's Orb lines are in a loop and I can't seem to get him to say anything about the house or make the option for it to come up.

* Yes I have done the quest for Mona, but she isn't there anymore ever since I bought Selena(?) off her.

* I talked to Ots and he does mention of said house being for sale by Preston, but that doesn't help either.

Anyone got any ideas, if this is a dead end caused by a bug, anyone got the console command to force it?

 

Did you go fishing?

 

Were you able to talk to Preston about his tooth again?

Sometimes you have to go through the whole tooth fixing dialog again just to let him know you have solved Mona's cash flow concerns.

 

I have, and that's where the loop keeps going.

 

I would load a save just before solving Mona's problem and try it again.

 

A little late for saves now :B. Ah well.

Anyone know the console command for it?

 

I realize this is an old thread, but I came here looking for an answer to Dankiller's final question (I think maybe my party couldn't buy the house because we killed the dentist), so in case anyone else does too:
