Not that I know of. I believe the maximum allotted expansions is currently set to 30, but I could be corrected on this.
2.Keep the smaller buildings for now and reorganize your hood to make them fit. If necessary, remove decorations from your hood so that you can pack in more economy buildings. Your IPH is quite low for your level, so you'll want as many money-earning buildings as you can possibly get.
Once you reach a solid IPH, then you can start thinking about removing the lower-leveled buildings to make room for the big-earners if you'd like. But even then, I'd hang on to as many as I could just for the IPH boost. But you've got to understand that this is coming from a dedicated camper - So I'm a bit biased when it comes to maximizing IPH.

4.With Syndicate bonuses in play now, it's trickier to answer that question. Defense wise having 2x your opponents Attack stat with your Defense provides full immunity. My best guess would be that a 100% successful attack would utilize a similar ratio. Keep in mind that there are several other invisible variables involved though, including Skill Points and Modifiers.
5.Keep your EXP gains as absolutely minimal as possible. For now, I would recommend that you completely stop regular PvP, and focus solely on building your IPH and fully equipping your mafia with max cash items. Collect your daily scratchers. Build up on as many defense buildings as you can fit in your hood without hindering your IPH. Don't worry about upgrading them. Alternatively, if you aren't as serious about camping, then focus solely on maximizing your RP:EXP ratio. So only rob high RP buildings, and avoid attacking.
Just my opinion on a few of your questions. Feel free to correct me if I'm wrong on anything![]()
