Investors signed contract, 2 weeks later want to reduce price

[Vanessa Perez]

What could possibly be going on? We were in the process of selling our M-Street home in Dallas, Tx and contacted a group of investors beforehand to see if they were interested. Right away they responded and came out right away and had an offer ready and everything. We negotiated on the price and 2 weeks later they say they are looking into how much everything is going to cost and they want to go even lower than the original offer.

Of course we aren't budging a dime. 

What could possibly be going on? They signed the contract already and we were already looking into purchasing another property  but luckily haven't made any offers. 

It's a difference of 24k, I have a feeling they're trying to cut costs everywhere, starting with us. Right now they have us waiting to see if they will be able to "come up with the money".

What do you guys think?
