Hi Lizzie,
You will be fine. You have identifyed the problem and are now working on the solution. Even if that means selling all, you'll still walk away well ahead of the masses, and be in a position to set yourself up for the next upswing.
You know, that is exactly what my hubby and I have done over the last 6 months. On a lot smaller scale than you, but we are glad we did. We are hopeless at making decisions, but sometimes the status quo is just not going to cut it.
Last year, we took quite a few profits from the sharemarket (and with what it is doing now, thank goodness!), used it to go on our Big Trip and to pay off our mortgage. While we were in Queensland, we started the process of developing the property we bought there 3 years ago. At the time we bought, we were confident of walking away with $200k profit. The thing is, there was a small but vital problem that we, the buying agent, or the council, didn't notice when we bought - which to cut a long story short, meant we couldn't develop the block as planned. It was a horrid situation to find ourselves in, and we had to admit it as a HUGE learning experience and cut our losses. Though we sold the property for $50k more than we bought it, because of negative gearing etc, we still made a loss. That hurt, but there was no point holding it anymore.
Other big changes followed. We came home to discover our dream home for sale. We bought it, and sold down the remainder of our Victorian IP for a large profit to enable us to buy the (upgraded) PPOR mortgage free. We shift next week, and have the money to do the place up to our liking, and with no debt, other than a margin loan on our remaining share portfolio.
The way we see it, we have a house that we never want to shift from, debt free, that we can leverage when the time is right. We sold our Vic IP for a good price, at what we think is a good time, the market possibly set to fall. We plan to gear up into IP again when the signs are right.
It wasn't easy for us to make such major changes, but I don't regret selling IPs like I once thought I would. We kind of feel like we are starting again, but from a much stronger position.
Anyway, just wanted to say Lizzie, that if you do end up sellling all, it is not as scary a position as it may feel right now. Sometimes plans have to be changed, for the greater long term good.
Good luck with whatever you do.
Lily
