jbatzmaru,
Sorry if I was a bit too sarcastic before. I tend to be that way, in case you haven't noticed.
In your purchase contract, it will state something along the lines of: If you do not have loan approval, at any time during the escrow, and/or prior to close, then this contract becomes null and void. Lennar will not be responsible for loan approval or guarantee of any loan approval. Lennar also, will not be responsible for any changes in lending guidelines/rates/job changes/or any changes in your loan application, and/or any ridiculous statements made by Gary Watts. Please ignore him, because we supplied him with the kool aid, so we know.
So.... since the lending guidelines changed, i.e. Fannie will no longer approve a loan where the seller (Lennar) is paying for HOA dues, then they are no longer responsible, and your contract could be and/or will be considered null and void. The idea that the HOA dues being paid may be part of <em>your</em> contract, but the loan approval part of the contract super cedes it. Ask a judge, I am sure he/she will say, sorry... but your contract states all parts of your contract were/are contingent of loan approval, and <em>you</em> no longer have a loan approval as the contract was written. This isn't Lennar's fault, it is the fault of the idiots who ruined lending, and now it is <em>you </em>who doesn't qualify.
What do you do now? Ask yourself how long you will really live there on a monthly basis, then calculate what that $7800 is on a monthly basis to recover it. Get Lennar to drop your payment, so that the difference is what it takes to recover the $7800 on a monthly basis by how long you plan on keeping the loan.
It can be done, but you need to be smooth about it. If you start to mention the contract, that <em>you</em> no longer qualify for, then you will get no where. I look forward to hearing what you were able to do.
