Moved into Budget Homes: Infra impact on prices

Moved to my flat in Budget Homes last month, and seeing 15-20% price hike near the new road. Honestly, infra improvements are crazy. Metro project aur new road se prices kitne badhe hain overall? Mera wala flat toh theek hai, but kaun se specific pockets ko zyada benefit mila hai yaar? Matlab, will this growth sustain? Should I consider another small investment there, ya ab already too late hai? Kya kisi ko pata hai.
