DinoRealty – real estate – land – lots- acreages

Hi my downstairs neighbors are under contract to buy my condo.
They first agreed back in May on a June 30th settlement date.
Before the June 30th settlement they & their lawyer went on vacation alledgedly and they asked to switch the date until August 3rd. They signed the contract and put 10% of purchase price in Escrow.
I was looking forward to this deal finally closing until my lawyer called and gave me bad news.
My neighbors are now saying they need an extension until the middle of August.
Im really frustrated, anxious and don’t feel trusting of them to finally see this deal through.
I need some advice. Shall I tell them no more extension and risk having to list my place for sale ?
And if they don’t perform, how can I keep any of the desposit they have in escrow with my lawyer ?
Im so mad because when I agreed to sell to the housing market was in better shape and now I may lose a lot if I have to sell in late Summer. If it helps with advice, I m in New Jersey. Thanks all
My lawyer isn’t being any help to me.
He says that I should give them yet another extension because I’ll probably lose money if I try and start selling it now to new people.
Very frustrating.
Also my lawyer has not reassured me that I can even keep the 10% deposit if my buyers don’t perform.
He told me something like in NJ it’s hard to hold onto the deposits even when the deal falls through.
