I recommend you DO NOT finance through NVR Mortgage. They have been known to alter contracts, and give people the option of signing the crap deals point blank at closing or default on their contract and lose tens of thousands on their non-refundable deposit. In one case, NVR/Ryan homes nailed reputable people that had good credit with a 14% APR, more than twice what was agreed long before closing. They signed under threat of losing their deposit and assumed they could just go to another bank to get a fair deal.

But it got worse...the Ryan Homes house was seriously defective, and thus they could not get refinancing, nor would Ryan Homes fix their house. It took these people almost two years to get their life back from Ryan Homes and NVR mortgage. This is just one case. Not all get their life back, once you get mixed up with these people.

Sure things work out in some cases, but do not believe that your contract is binding to NVR. The rule of law is designed to serve them, not you the buyer. Try to find a mortgage broker or actual bank, that doesn't just use trust as a logo. You can still get your incentives without helping the pres of NVR mortgage department make his $5 mil bonus, on top of his meager $300,000 a year salary.

THE BOTTOM LINE anyway you cut it, the goals of forcing NVR financing on buyers is to extract back any benefits you think you're getting through incentives. People have successfully gone through a different broker or realtor, because of the bad terms NVR tried to stick them with. They still got the buyer incentives without tipping NVR, which is nothing more than a broker anyway.

Info based on this victims letter and other exchange I had with them.

I am sorry about your problems. 
We have been fighting Ryan Homes for almost 3 years now.  $15,000 in attorney fees, we are no closer then the day we started.  I am really disgusted by the morals and ethics of Ryan Homes.
NVR Mortgage sold us up the river with our mortgage.  We were paying about 15% interest.  We were not able to refinance with another bank or mortgage company because of the damage to the house.  We were paying about $1,700/month for a mortgage the should be about $950/month.  This has about bankrupted us.  My uncle saw our problem and helped us out.  He loaned us the money to pay off our current mortgage.  Now we make payments to him of $900/month.  Once the house is fixed, we will refinance at a bank and pay my uncle back in full.  I trust the Lord will take care of us through all of this.  In the Bible it says all things work for the good.  This is rough to go through, but we will be better people in the end

Kind of amusing. This is Ryan Homes/ NVR Mortgage promo (linked below) on why NVR Mortgage is better than your bank for buying Ryan Homes. Both sides of the story so to speak. A page on why to finance through NVR accuses most all other banks of abusive practices which have been reported to me by people who dealt with NVR mortgage.  Either their customers are lying to me or NVR is lying here. People are not always ripped by NVR, but in my informed opinion, they're fully willing and able. According to their customer complaints, almost all the schemes they warn that only other banks do, NVR Mortgage has actually done. It would seem truth in lending is hype, not enforced law.
