Why do you have to meet with them at all?
It's your home isn't it?
Try telling them that you appreciate their concern but you're not interested in meeting with them now and that if you change your mind at any point you'll be happy to contact them. Smile politely as you say it.
If they ask you why you don't want to meet with them, remember that you don't have to answer their questions.
Just smile politely and repeat your statement that you appreciate their concern but you're not interested in meeting with them now and that if you change your mind at any point you will be happy to contact them.
If they ask if you have something to hide, smile politely and tell them that you appreciate their concern but... (see above).
Keep up the broken record as long as it takes for them to realize that you're sticking by what you said.
