Sorry about the paucity of information but it's been awhile since I read this and my memory isn't what it once was. Young guy but an old fire station and turns it into his home. A woman across the street worked at the realty office for which he bought it. She has a daughter his age. They are both into fast cars. Anyone with a memory better than mine?
Might be "Echo by Reluctant Sir"

It is "Echo". Sorry for not acknowledging it sooner. Old age doesn't just affect the memory; it also affects the time you spend visiting doctors - four appointments in two days. Thanks for jogging my memory with "Echo".
There is another where the guy is a troubleshooter and buys the place on the first ir second chapter, with everything else too
Seems likely that the OP is looking for Echoes since every particular slots in easily. But I would be interested in the one you mentioned. If you recall the name of the story or author let us know.
