Is it to early to inquire about a specific house 7 months out?

[Phil Kagebein]

Like the description says, I want to purchase a duplex as my first property. I've been browsing houses on the market currently just out of curiosity and to practice analyzing them. During this I found one house which I really like and think will cash flow well. However, I can't leave my current lease until May 1st. There's obviously no guarantee it's still on the market come ~February. Since I haven't gone through the home buying process before, I'm just wondering if it's even common/heard for sellers to even consider offers which close over half a year away. Appreciate any thoughts you have. Thanks!
