I feel bad for you. Keep in mind you don’t have a very good pool of buyers, be assertive but carefully.If you want to get tough you could demand an increased deposit and actually anything reasonable that you want. If you don’t need to make too many demands It might be better just to chalk it up to experience and go on assuming that your deal is going to close.You should at the very least get it back on the market if the buyer is holding things up but then just continue to be nice and patient. Demanding occupancy after the sale could kill the deal if the buyer is as weak as the one SD Realtor is describing above.I don’t recommend calling the Mortgage people unless both agents seem completely incompetent and then you should go your agents broker and ask that person to work with the buyer’s agents broker.Your remedy after that and you absloutely don’t need to worry about it yet, is to go to the local Realtors Board. Best wishes.
