Congrats! I bought my first house a year ago, and have been working non-stop to try and have it finished and landscaped, etc.... I'm almost done! Going from living in an apartment and having annual inspections where I would cover my old Vision racks with fabric and then lean surfboards on them, hang wetsuits, hang paintball guns, throw extra bike parts, have some apehangars jutting out of one of the racks, etc... Tried to make the second bedroom look like a storage room, which bugged the hell out of me since I am a neat freak! Instead of covering racks, now I tore down a wall and made one big snake room! I love owning!
As far as coming off as bragging... Buying a house has to be the one of the most, if not the most stressful/exciting purchase in your life. You cant help be excited and want to share! If that is too much for others to handle, then that is on them!
