Lender to offer low financing for new construction builds?

[Connor Williams]

I saw another builder local to me offering 4.99% financing. 
my question is how or who can offer financing like this on houses I build ? I am guessing there is either a preferred or in house lender with large amounts of credit to get to this? 

I want to learn more. 4.99% for buyers is a game changer selling 6 new construction houses

 You just buy down the rate for the buyer. The cost to do this just comes out of the total profit margin.
