@Anthony Bonafide - to be clear. The builder is not charging you more than what was agreed upon. The lender for the acquisition has been arranged by the builder. The lender hired an appraiser to obtain the appraisal for the loan. The loan is for "X%" of the contract price or appraised value. The agreed upon price is $572,000 and you have $44,000 in deposit and expected to pay another $5,000 for closing costs. So, if I understand this correctly, you assumed a loan of 92%. But because the appraisal came in $50,000 lower ($522k) you have to close the gap. Is this correct?
A few thoughts if those assumptions above are correct. There is $102,000 in upgrades. The builder would not have promoted the lender if they couldn't finance the "basic" package. The lender would not have selected appraisers who would not support the "basic" package. A loan of 92% is a high debt to loan value.
Options after requesting to see the appraisal:
1. new lender new appraiser
2. contest the appraisal by reviewing the comps and seeing if there are better ones, or if the assumptions the appraiser made are correct.
3. ask the lender to compare the appraisal to other homes in the subdivision
4. contest the upgrades with the seller based upon the fact they appraised at 50% of the amount charged.
5. Pay the $50,000 at closing, move in and enjoy the home.
What are they saying about the appraisal is true: Only can be determined if they show you the appraisal. See if the comps are accurate.
What does this mean for the property value: Maybe nothing. When a bank (NOT THE BUILDER) requests more equity it is because they don't feel secure, and they are "hedging their bet". The bet is if they have to foreclose will they be able to sell it at or above the loan value. The lower the loan, the more security they have. It is strange for the builder/agent for the builder to be communicating to you what the lender requires rather than you talking directly to the bank. I would call the lender directly and ask for the appraisal, then base my decision upon that.
