What is builder's turf? How many levels are there? How many XP does it take to get to level 3? Do I get charisma buffs to my stats at level 5? 
Srsly, tell me of builder's turf.
Builder's turf is the crap the builder throws down so that when you look at the place it has a lush, deep, green lawn. Which dies in about 60 days. Level 1 is annual rye - sprouts like crazy and looks wonderful in 7 days or so. Great for patching bald spots just before the big outdoor wedding, or for hiding dog-pee dead zones until after the house closes.
Unless you have had a soil analysis and prepped with truckloads of chemicals and conditioners, any of the fescuesand perennial ryes are level 2 builder's turf. Throw it down, watch the birds eat most of it, and see the rest wash downhill in spite of the straw or special mats you put on top of the seeds.
The reason those old geezers who putter about all day working on their lawns is because it takes that much effort to maintain most home meadows because they are based on a grass type that is not properly suited to the soil. Laying locally grown turf may give you better results than seed if the underlayment is properly prepped, as you have a good root system already in place.
Go look at your local golf courses and find out what they are growing and what fertilizers they are using, as well as their schedules for areating and dethatching.
Personally, if I ever had to do a lawn again I'd pay someone to plug zoisa every 3 inches. Two tears tops to fill in, and it reaches max height and density by then too. Green if you put water on it, a nice kakhi if you don't. Can stay dormant for years and needs mowing maybe once a year if you are actually watering it instead of waiting for the rain. (Just watch out for neighbors who complain that it is encroaching on their lawns - or who are cutting plugs from yours.)
stay safe.
