BMR is almost as good as Irvine Ranch when it comes to making money. Lots are sold in small chunks to developers. Developers like it because they don’t have to carry a large loan for 100 lots. They only have to carry one for 15 at a time. BMR likes the strategy because they NEVER have to worry that a builder that just bought 200 lots just went bankrupt and the land will be sold to the next developer NOT by BMR but by the bankruptcy judge and the bank for pennies on the dollar. Thus the new developer reduces the lot price by 1/2..which reduces all of BMR lots! What BMR/Irvine want is total control of the lot price. That’s how they make money.
Even though BMR developed (graded, road, utilities) doesn’t mean the lots are sold yet…only plotted for a certain sized house and whether it’s alley loaded or not.
So yes, ANY builder can buy the remainder of the red lots.
As for why Pasado was placed by the city park all by it’s lonesome is most likely that’s where BMR had the free land that wasn’t reserved AND had the best price. Lots over looking the park is a big bonus…Even though residents will have to walk farther to get to the community pools.
